Payroll, Management Fees, and G&A Scaling: How Operating Expenses Change with Property Size

Key Takeaways

What Management Fees Cover

The property management fee is a recurring charge paid to the entity responsible for the day-to-day operations of a commercial property. That entity may be a third-party management company, an in-house management division of the ownership group, or a related-party manager affiliated with the general partner. Regardless of the organizational structure, the fee compensates for a defined scope of services that falls into several categories.

Rent collection and income management. The management company is responsible for billing tenants, collecting rent, processing payments, enforcing late fees, and managing delinquencies. This includes maintaining tenant ledgers, reconciling bank deposits, and reporting income to the owner on a monthly basis. For commercial properties with complex lease structures (NNN, modified gross, percentage rent), this also includes CAM reconciliation, expense pass-through calculations, and annual tenant billing adjustments.

Tenant relations and lease administration. The manager handles tenant communications, maintenance requests, move-in/move-out procedures, lease renewals, and lease enforcement. In multifamily, this includes resident screening, application processing, and compliance with fair housing regulations. In commercial, this includes tenant improvement coordination, rent commencement tracking, and co-tenancy monitoring.

Maintenance coordination and vendor management. The manager oversees routine maintenance, preventive maintenance programs, landscaping, janitorial services, and emergency repairs. This includes soliciting bids from vendors, negotiating service contracts, managing work orders, and conducting property inspections. The manager typically does not perform maintenance directly but coordinates with third-party vendors and on-site maintenance staff.

Financial reporting and budgeting. Monthly financial reporting to the owner, including income statements, balance sheets, variance reports against budget, and capital expenditure tracking. The manager also prepares the annual operating budget, which the owner reviews and approves before the start of each fiscal year. Institutional owners require reporting in a standardized format that feeds directly into their portfolio accounting systems.

Regulatory compliance. The manager ensures the property complies with local, state, and federal regulations, including building codes, fire safety, ADA requirements, environmental regulations, and tenant protection laws. In affordable housing, this extends to income certification, rent restriction compliance, and regulatory agency reporting.

Fee Structure Taxonomy

Management fee structures vary across asset classes, markets, and operator preferences. The five common structures each create different economic incentives and risk-sharing arrangements between the property owner and the management company. Understanding these structures is essential for underwriting the management fee line in a pro forma and for evaluating management proposals during the procurement process.

Percentage of Gross Revenue

A fixed percentage of gross scheduled rent (also called gross potential rent), charged regardless of collections. This basis is less common than a collected-revenue basis, and practitioner guides caution against fee clauses based on rent due rather than rent collected. If the property has 200 units at an average rent of $1,500/month and the management fee is 4% of gross, the monthly fee is $12,000 (200 x $1,500 x 4%), regardless of how many units are actually occupied or how much rent is actually collected.

This structure gives the manager a predictable revenue stream but creates a misalignment: the manager earns the same fee whether occupancy is 95% or 85%. The manager has an incentive to set high asking rents (which increase gross revenue) but no direct penalty for vacancy or collection loss. For this reason, the percentage-of-gross structure is most appropriate for stabilized properties with consistent occupancy, where the manager's primary job is rent optimization rather than lease-up.

Percentage of Collected Revenue

The fee is calculated on actual collected revenue rather than scheduled revenue. This is the more common basis in commercial property management: Piping Rock Partners' guide describes percentage fees tied to rent collections as the most common structure, and Feldman Equities reports that most commercial property management companies charge a percentage of gross rent collected. If the same 200-unit property collects $270,000 in a month where $300,000 was billed (90% collection rate), the 4% fee is $10,800 rather than $12,000. This structure aligns the manager's revenue with the owner's cash flow. The manager bears some of the economic impact of vacancy and bad debt, which incentivizes aggressive collections and occupancy management.

As Feldman Equities' management fee overview notes, it is important to clarify whether a management contract specifies "gross" or "collected" as the fee basis, because the difference can be material, particularly during lease-up, repositioning, or in markets with elevated delinquency. A 4% fee on gross revenue and a 4% fee on collected revenue are not the same number.

Flat Monthly Fee

A fixed dollar amount per month regardless of property revenue or size. This structure is most common in single-tenant NNN properties, small commercial properties, and properties under long-term, low-touch management contracts. A flat fee of $3,000/month for a 20,000 SF single-tenant office building provides cost certainty for the owner and revenue certainty for the manager.

The risk in a flat fee structure is that it does not adjust for inflation, rent growth, or changes in property complexity. A flat fee set at $3,000/month in Year 1 of a 5-year contract may undercompensate the manager by Year 5 if property revenue has grown 15% while the fee has stayed constant. Sophisticated flat fee contracts include annual escalation clauses (for example, 2% to 3% per year) to address this drift.

Per-Unit Fee

A fixed dollar amount per unit per month, common in multifamily properties, particularly in institutional portfolios where standardization across properties simplifies budgeting and comparison. A per-unit fee of $50/unit/month on a 200-unit property produces a $10,000 monthly fee ($120,000 annually). The per-unit structure makes it easy to benchmark management costs across properties of different sizes and to model fee scaling as units are added to the portfolio.

Per-unit fees are particularly common in affordable housing, where regulatory rent restrictions make percentage-of-revenue fees less practical. A property with rents capped at $800/month under a LIHTC restriction cannot support the same percentage-based fee as a market-rate property at $1,800/month, but the management workload per unit is comparable.

Hybrid: Base Plus Incentive

A combination structure with a reduced base fee (for example, 50 to 75 basis points below the standard percentage) plus a performance-based incentive tied to specific operating metrics. Common incentive triggers include NOI exceeding the approved budget, occupancy exceeding a target threshold, or tenant satisfaction scores meeting a benchmark. In an illustrative structure, the incentive portion is 25 to 50 basis points of revenue, paid quarterly or annually upon achievement.

The hybrid structure creates the strongest alignment between the manager and the owner because it directly links a portion of the manager's compensation to the operating outcomes that drive investor returns. An institutional owner running a value-add strategy may structure the fee as 2.5% base plus a 0.5% incentive triggered when NOI exceeds the Year 1 budget by 5% or more. This gives the manager a financial stake in the business plan's success.

Benchmarks by Asset Class

Management fee percentages and total management costs vary significantly by asset class because the operational complexity, tenant interaction frequency, and staffing requirements differ. A 200-unit multifamily property requires daily tenant interaction, 24/7 emergency maintenance, and a full-time leasing operation. A 200,000 SF single-tenant industrial warehouse requires monthly invoice processing and quarterly property inspections. The management workload per dollar of revenue is fundamentally different, and fee structures reflect that difference.

The benchmarks below reflect institutional market conditions. Actual fees vary by market, property quality, manager reputation, and negotiating leverage. For market-level operating expense data, see IREM's Income/Expense IQ National Summary.

The distinction between the management fee percentage and the total management cost percentage is critical. The fee is what the management company charges for its oversight services. The total management cost includes the fee plus all on-site payroll, benefits, and G&A overhead that the property bears. For a multifamily property, the fee might be 3% of EGR, but total management costs (including on-site staff) are roughly 11% to 15% of EGR. An underwriter who models only the management fee and omits on-site payroll will materially understate operating expenses and overstate NOI.

How Asset Complexity Drives Costs

The cost difference between asset classes is driven by three factors: tenant interaction frequency, physical plant complexity, and regulatory burden. Multifamily properties have the highest tenant interaction frequency because residential tenants generate daily maintenance requests, lease inquiries, and community management needs. Office properties have moderate interaction frequency but high physical plant complexity (HVAC systems, elevators, life safety systems). Industrial properties have low interaction frequency and relatively simple physical plants, which is why management fees and total costs are the lowest in the asset class spectrum.

Self-storage is an outlier. While the management fee percentage (5% to 7%) is moderate, total management costs consume a disproportionate share of effective gross revenue because the asset class requires on-site staff, intensive revenue management (daily rate adjustments, promotional pricing), and marketing to maintain occupancy. The revenue per square foot is low relative to other asset classes, so the management cost as a percentage of revenue is disproportionately high even though the absolute dollar amount per facility is modest.

On-Site Staffing Models by Property Size

On-site payroll is typically the largest single component of total management cost, often exceeding the management fee itself. The staffing model varies by property size, asset class, and market. In multifamily, which has the most developed on-site staffing conventions, the standard positions are property manager, assistant property manager, leasing agent, maintenance supervisor, maintenance technician, and janitorial/grounds staff.

The table below shows typical on-site staffing models for multifamily properties at four size tiers, with fully loaded costs (salary plus benefits plus payroll taxes, assumed here at 1.25x to 1.35x base salary). These are illustrative national-average assumptions. Markets with higher cost of living (New York, San Francisco, Boston, DC) run above these figures and secondary markets (Charlotte, Nashville, Phoenix, Tampa) run below them.

Several patterns emerge from the staffing model. First, the property manager role is the fixed cost anchor. A 50-unit property needs a half-time property manager at the same salary rate as a 150-unit property's full-time property manager. The difference is that the 150-unit property spreads that fixed cost across three times as many units. Second, maintenance technicians scale roughly linearly with unit count, at approximately one technician per 125 to 150 units (one maintenance FTE, including the supervisor, per 75 to 100 units), because maintenance workload is proportional to the number of units generating service requests. Third, leasing staff scales with turnover volume, not total unit count. A 300-unit property with 50% annual turnover needs 1.5 leasing agents to handle 150 move-outs and move-ins per year. A 300-unit property with 30% turnover may need only 1.0 leasing agent.

The per-unit payroll cost decline from $2,100 at 50 units to $1,252 at 500 units illustrates the core economy of scale in property management. The fixed-cost roles (property manager, maintenance supervisor) are spread across a larger base, while the variable-cost roles (technicians, leasing agents) scale at a lower ratio than one-to-one with unit count.

The Management Cost Scaling Curve

Total management cost per unit is a function of three components: the management fee, on-site payroll, and G&A overhead. Each component scales differently with property size, producing a total cost curve with distinct inflection points. Understanding the shape of this curve is important for acquisitions underwriting (especially when comparing properties of different sizes), for portfolio construction strategy (where the operator is optimizing total portfolio-level management costs), and for evaluating the self-management decision.

The following figure shows the total management cost per unit for a multifamily property at different size tiers, decomposed into its three components. The data assumes a 3.5% management fee on gross revenue, average monthly rent of $1,600/unit, and national average staffing costs.

The scaling curve reveals several important features. First, the management fee component ($672/unit at 3.5% of $1,600/month average rent) is flat across all property sizes when expressed on a per-unit basis, because the fee is a percentage of revenue and revenue per unit is assumed constant. The fee provides no economies of scale on its own. All of the per-unit cost reduction comes from payroll and G&A spreading.

Second, the steepest cost decline occurs between 50 and 200 units. This is the range where the first property manager and maintenance supervisor positions transition from part-time or shared to dedicated full-time roles, but the unit count grows faster than the staffing requirement. A 50-unit property needs a half-time property manager and a half-time maintenance supervisor, costing roughly $65,000. A 200-unit property needs one full-time property manager and one full-time maintenance supervisor, costing roughly $140,000. The payroll doubled, but the unit count quadrupled, so the per-unit cost fell by half.

Third, the curve flattens above 300 units. Between 300 and 500 units, the staffing table adds about $183,000 of payroll for 200 units, or about $915 per incremental unit (one technician and half a grounds FTE per 100 units, plus a quarter of a leasing agent and pay step-ups). That is still below the $1,252 average at 500 units, so per-unit cost keeps falling, but slowly. Properties above 500 units see diminishing returns on the per-unit scaling because the variable-cost positions (technicians, leasing agents) now dominate the payroll, and these roles scale roughly linearly with unit count.

Inflection Points for Portfolio Strategy

The inflection points on the scaling curve have practical implications for portfolio construction. An operator evaluating two acquisition opportunities of equal total value should consider the management cost differential. Two 150-unit properties will cost approximately $522,000 in combined annual on-site payroll (2 x $261K). A single 300-unit property with the same total unit count will cost approximately $443,000. The $79,000 annual savings flows directly to NOI. At a 5.0% cap rate, $79,000 of annual NOI savings capitalizes to about $1,580,000 of value (more at exit if payroll inflation widens the gap).

This math explains why institutional multifamily investors prefer larger properties. The per-unit management cost advantage of a 300-unit property over two 150-unit properties is not just an operational convenience. It is a value creation lever that compounds through the cap rate multiplier.

Self-Management vs. Third-Party Economics

The decision to self-manage or engage a third-party management company is one of the most consequential operating decisions a property owner makes. Self-management eliminates the management fee (typically 2.5% to 4.5% of gross revenue for institutional multifamily) but requires the owner to build and maintain an internal management infrastructure. Third-party management outsources operational complexity but introduces agency costs, less direct control, and the management fee itself.

Self-Management Cost Structure

Self-management requires the owner to absorb several cost categories that a third-party manager covers through the management fee and their own corporate overhead. These costs include the following (cost ranges are illustrative assumptions):

• Regional management: A regional manager or vice president of operations to oversee multiple properties. Loaded cost: $120,000 to $180,000 annually. A regional manager can typically oversee 1,500 to 2,500 units, depending on geographic density.
• Accounting and reporting: A property accountant or accounting manager to handle financial reporting, accounts payable, bank reconciliation, and owner distributions. Loaded cost: $65,000 to $90,000. One accountant can handle 800 to 1,200 units.
• Human resources and compliance: HR support for on-site employees, including hiring, training, benefits administration, workers' compensation, and employment law compliance. This can be a fractional role or outsourced to a PEO (professional employer organization). Cost: $25,000 to $50,000 annually for a 1,000-to-2,000-unit portfolio.
• Technology and systems: Property management software (Yardi, RealPage, AppFolio, Entrata), accounting systems, work order platforms, resident portals, and data infrastructure. Cost: $8 to $15 per unit per month ($96 to $180 per unit per year), counted here only to the extent it is not already carried in the property-level G&A line.
• Office overhead: Corporate office space, insurance, legal, and general administrative costs attributable to the management function. Cost: $50,000 to $100,000 annually for a small to mid-size portfolio.

Breakeven Analysis

The breakeven point for self-management occurs where the total cost of the internal management infrastructure equals the third-party management fee that would otherwise be paid. Consider a portfolio of multifamily properties at $1,600/month average rent.

The breakeven occurs at approximately 650 to 700 units in this analysis (interpolating between the 500-unit and 1,000-unit rows gives about 670 units). Below that threshold, the fixed infrastructure costs of self-management (regional manager, accountant, HR, technology, office) exceed the third-party fee. Above it, the fee scales linearly with revenue while the infrastructure costs scale sub-linearly, creating a widening savings gap.

However, the raw economics do not capture the full picture. Several qualitative factors shift the breakeven:

• Geographic concentration matters. A portfolio of 1,500 units spread across 15 properties in a single metro area is much more efficient to self-manage than 1,500 units across 5 properties in 5 different states. The multi-state portfolio requires multiple regional managers, state-specific compliance expertise, and travel costs that erode the savings. The single-metro portfolio allows one regional manager to visit all properties weekly.
• Operational expertise is not free. A GP that has never operated properties directly must hire experienced property management professionals, implement systems, and build institutional knowledge. The learning curve has real costs: higher turnover among initial hires, suboptimal vendor contracts negotiated without scale leverage, and NOI underperformance during the transition period.
• Opportunity cost of management attention. Running a management company requires executive bandwidth. For a GP focused on acquisitions and capital raising, the time spent managing a management company is time not spent sourcing deals or maintaining investor relationships. This opportunity cost is real but difficult to quantify.

The practical breakeven is higher than the pure financial breakeven. Operators with 1,500 to 2,500 units in a single market may continue to use third-party management because the operational simplicity, reduced executive distraction, and avoided startup costs outweigh the fee savings. Operators who cross the 3,000-unit threshold in a single market commonly self-manage because the savings are too large to ignore and the portfolio size justifies a dedicated management infrastructure.

Fee Negotiation Dynamics

Management fees are negotiable, and the negotiated rate can differ significantly from the management company's published rate schedule. The factors that create negotiation leverage include portfolio size, contract duration, property quality, geographic density, and the competitive dynamics of the local management market.

Volume Discounts

The most powerful negotiation lever is portfolio size. A management company's marginal cost of adding the 10th property to a client relationship is lower than adding the 1st, because the regional oversight, accounting infrastructure, and client reporting are already in place. This cost structure allows the manager to offer volume discounts without sacrificing margin.

Typical volume discount structures in multifamily management:

The dollar impact of these discounts is significant. On a 2,000-unit portfolio with $1,600/month average rent, the difference between 4.0% and 2.75% is $480,000 per year. At a 5.0% cap rate, that savings represents $9,600,000 in portfolio value. This is why fee negotiation is not an administrative exercise. It is a value creation lever.

Portfolio vs. Property Contracts

An owner with multiple properties can negotiate a single portfolio management agreement (PMA) rather than individual property-by-property contracts. The portfolio PMA creates several advantages. First, it consolidates negotiation leverage into a single contract. Second, it allows the manager to cross-staff properties, moving maintenance technicians or leasing agents between properties based on seasonal demand. Third, it simplifies termination provisions because the owner can restructure or terminate the entire relationship with a single notice, rather than navigating different termination dates across multiple contracts.

The portfolio PMA also creates a retention incentive for the manager. If the manager knows that losing one property means losing the entire portfolio, they are more likely to invest in performance, respond to owner concerns, and proactively address operational issues. This dynamic is particularly valuable in value-add strategies where the manager's operational execution directly drives investor returns.

Performance-Based Renewals

Owners can structure management contracts with performance-based renewal provisions rather than automatic renewals. Under this structure, the initial contract term is 1 to 2 years, with renewal contingent on the property meeting defined operating benchmarks: NOI within a specified range of the approved budget, occupancy above a threshold, tenant satisfaction scores, and completion of capital projects on schedule.

The performance renewal structure gives the owner an annual evaluation mechanism without the disruption of a formal termination. If the manager underperforms, the contract simply does not renew. This is a cleaner exit than invoking a for-cause termination clause, which often requires documentation of specific management failures and can trigger disputes over the definition of "cause."

Transition Costs When Switching Management Companies

Switching management companies is not costless. The transition may take 60 to 90 days and involves several direct and indirect costs that the owner should factor into the switching decision. The dollar and time figures below are illustrative.

• Transition management fees. The outgoing manager may charge a termination fee (often one month's management fee) and the incoming manager may charge a takeover or onboarding fee ($5,000 to $15,000 per property) to cover the cost of learning the property, migrating data, and setting up systems.
• Staff turnover risk. On-site staff may leave during a management transition, particularly if the outgoing manager offers them positions at other properties. Replacing a property manager or maintenance supervisor takes 30 to 60 days and costs $5,000 to $10,000 in recruiting and training expenses. During the vacancy, the property operates with reduced staffing, which can affect maintenance response times and tenant satisfaction.
• System migration. Tenant data, lease documents, vendor contracts, work order history, and financial records must be transferred from the outgoing manager's systems to the incoming manager's platform. This migration typically takes 30 to 45 days and is a common source of errors, lost records, and tenant confusion (especially around rent payment instructions and auto-pay setups).
• Operational disruption. During the transition period, routine operations may slow. Maintenance response times increase, vendor relationships need to be re-established, and tenant communications may be inconsistent. The NOI impact of a poorly managed transition can be $20,000 to $50,000 per property over the transition quarter, depending on property size.

Direct one-time costs run about $20,000 to $40,000 per property, plus an NOI drag of $20,000 to $50,000 over the transition quarter, for an all-in $40,000 to $90,000. This cost sets a threshold for switching: the fee savings or performance improvement from the new manager must exceed the all-in transition cost within a reasonable payback period (for example, 12 to 18 months) to justify the disruption.

The Management Company P&L

Understanding how the management fee flows through the management company's own economics helps owners evaluate whether a quoted fee is reasonable, whether the manager can sustain that fee level without cutting corners, and where the manager's incentives may diverge from the owner's interests.

A typical third-party multifamily management company operates at the following margin structure:

The wide range in operating margin (15% to 42% of base fee revenue) reflects the enormous variation in management company scale. A small management company overseeing 2,000 units operates at the low end of this range because its fixed costs (regional management, technology, corporate overhead) are spread across a small fee revenue base. A large national platform managing 50,000+ units operates at the high end because regional management, accounting, and technology costs scale sub-linearly with portfolio size.

This margin structure has important implications for fee negotiation. A manager operating at a 20% margin on base fee revenue and a 3.5% fee does not have room to cut to 2.5% without either reducing service quality or cross-subsidizing from other revenue sources (leasing commissions, construction management fees). Conversely, a manager operating at a 40% margin on base fee revenue and a 4.0% fee has ample room to discount to 3.0% while remaining profitable. Understanding the manager's scale and cost structure helps the owner calibrate how far to push in negotiations.

Where Manager and Owner Incentives Diverge

The management company P&L creates several points of potential misalignment. First, the manager benefits from maximizing ancillary fee revenue (leasing commissions, construction management fees) that is charged to the property. An aggressive leasing commission schedule or inflated construction management fee can offset a competitive base management fee, making the total cost higher than it appears at first glance.

Second, the manager benefits from vendor markup, where the manager adds a margin on top of vendor invoices before passing the cost to the property. As Piping Rock Partners' guide notes, some managers add 10% to 20% on top of vendor invoices, which can apply to maintenance and repair work. An owner who sees a $5,000 invoice for plumbing work may not realize that roughly $450 to $830 of that cost is the manager's markup. Some management contracts prohibit vendor markup. Others allow it but require disclosure. The owner's management agreement should explicitly address whether vendor markup is permitted and, if so, what percentage.

Third, the manager has a natural incentive to staff conservatively to protect their own margin. Hiring an additional maintenance technician costs the manager nothing (it is charged to the property's payroll line), but it does not increase the manager's fee revenue either. The manager's staff productivity metrics (revenue per regional manager, units per accountant) improve when the portfolio grows faster than the corporate headcount. This can lead to understaffing at the corporate level, which manifests as slow financial reporting, delayed budget preparation, and insufficient regional oversight.

G&A and Overhead Allocation

General and administrative (G&A) expenses represent the property's share of overhead costs that are not directly attributable to a specific operating function (maintenance, leasing, or management) but are necessary for the property to operate. G&A sits between the management fee and on-site payroll in the expense hierarchy: it is not the fee the manager charges, and it is not the cost of on-site staff, but it is a real cost that reduces NOI.

Typical G&A line items include:

• Office supplies and equipment. Computers, printers, office furniture, and consumable supplies for the on-site office. Cost: $1,000 to $3,000 per year for a typical multifamily property.
• Telecommunications. Phone systems, internet service, and cell phone allowances for on-site staff. Cost: $3,000 to $8,000 per year.
• Professional services. Legal fees (lease review, tenant disputes, eviction processing), audit and tax preparation, and consulting. Cost: $5,000 to $20,000 per year, highly variable.
• Licenses and permits. Business licenses, elevator permits, pool permits, and other regulatory compliance costs. Cost: $2,000 to $5,000 per year.
• Travel and training. Travel costs for off-site training, industry conferences, and fair housing certification courses for on-site staff. Cost: $2,000 to $5,000 per year.
• Accounting and data processing. The property's share of centralized accounting services and property management software license fees. Cost: $100 to $180 per unit per year.
• Bank charges. Lockbox fees, ACH processing fees, and wire transfer fees associated with rent collection and vendor payments. Cost: $1,000 to $3,000 per year.

In total, G&A overhead typically runs about $130 to more than $1,000 per unit per year for multifamily properties (at the high end for properties under 100 units), with the per-unit cost declining as property size increases (because many G&A items are fixed costs that spread across more units at larger properties). For office and industrial assets, G&A is commonly expressed as a percentage of gross revenue or on a per-square-foot basis.

G&A in the Pro Forma

Some pro forma templates include G&A as a sub-line within the management fee category. Others break it out as a separate line item. The best practice is to model G&A as a separate line item, distinct from both the management fee and on-site payroll, because the three categories have different growth assumptions and different sensitivity to property performance.

• The management fee grows in proportion to gross revenue (because it is a percentage of revenue).
• On-site payroll grows at an assumed 3% to 4% per year (reflecting annual wage increases and benefits cost inflation), independent of revenue growth.
• G&A grows at an assumed 2% to 3% per year (general inflation), with some components (technology, professional services) potentially growing faster.

Modeling all three as a single line item with a uniform growth rate obscures these differences and can produce materially inaccurate expense projections over a 5-to-10-year hold period. A pro forma that blends management costs into a single 10% of EGR line item in Year 1 and grows it at 3% per year will diverge from reality because the fee component (which is linked to revenue, not inflation) may grow at 4% to 5% in a strong rent growth market.

Common Mistakes Practitioners Make

1. Modeling only the management fee and omitting on-site payroll. The management fee is the most visible management cost, but it is typically less than a third of total management expense. A 3% fee on a 200-unit multifamily property generates $115,200 annually, but on-site payroll adds $310,000 to $440,000. An underwriter who models only the fee understates management costs by roughly 75% to 80%. Always model the full stack: fee plus payroll plus G&A.

2. Using the same management cost percentage for properties of different sizes. Applying a blanket 10% of EGR management cost assumption to every property in a portfolio ignores the scaling curve. A 50-unit property may run at roughly 16% to 17% of revenue for total management costs, while a 400-unit property runs at roughly 11% to 12%. Using 10% for both understates both. The error on the small property (about 6 to 7 points of revenue) is several times the error on the large one (about 1 to 2 points), which produces inaccurate NOI estimates and overstates the small property's value most.

3. Ignoring the fee basis (gross vs. collected). A 4% fee on gross revenue and a 4% fee on collected revenue produce different dollar amounts, particularly during lease-up or in periods of elevated vacancy and bad debt. A property at 90% economic occupancy will pay about an 11% higher fee under a gross basis than under a collected basis (equivalently, the collected-basis fee is 10% lower). The management agreement specifies the fee basis. The pro forma should match.

4. Failing to account for ancillary management fees. The base management fee does not capture leasing commissions, construction management fees, setup/takeover fees, or vendor markups. As Piping Rock Partners' guide tabulates, leasing commissions run 4% to 6% of gross rent on new leases (1% to 3% for renewals) and construction management 5% to 10% of project cost. Commercial Real Estate Loans' fee overview adds that most managers also charge lease-up and renewal fees and a maintenance mark-up, and cites a broader 4% to 12% of rent range for commercial property management fees.

5. Applying residential management benchmarks to commercial properties. Residential property management fees for single-family rental are typically a higher percentage of gross than institutional commercial management fees (1% to 7% depending on asset class) because the workload per dollar of revenue is higher for smaller, dispersed residential portfolios. Using residential benchmarks for a 200-unit multifamily or a 100,000 SF office building will grossly overstate the management cost.

6. Not escalating payroll costs separately from the management fee. The management fee grows with revenue. On-site payroll grows with wage inflation. These growth rates are different. In a flat rent market where revenue grows at 0%, the management fee stays flat, but on-site payroll still increases at an assumed 3% to 4% annually due to wage inflation. A pro forma that ties all management costs to a single revenue-linked growth rate will understate payroll costs in later hold years.
