NOI: Institutional vs Broker Calculation, and the Definitional Differences That Move Cap Rates 25 BPS

Key Takeaways

A note on the numbers. The ranges in this article for NOI impact, reserves, management fees, vacancy, and time per step are illustrative underwriting assumptions, not survey statistics. "Institutional NOI" here means the underwriting build described in this article, and individual shops differ. The worked example is a hypothetical deal, not a specific transaction.

Why Broker NOI Lies, and Why Institutional Buyers Re-Build It

A broker's offering memorandum is a sales document, not an underwriting document. The NOI on the front page of an OM is computed by people whose compensation is tied to clearing the sale at the seller's asking price, not by people whose mandate is to protect an investment committee from buying at the wrong cap. That is not a moral judgment. It is a structural feature of the brokerage business. The broker's NOI is optimized for the trade. The institutional NOI is the number that survives an IC and reconciles to actuals 24 months later.

The gap between the two numbers is rarely accounting fraud and almost always definitional. A broker NOI uses market rents on the rent roll because the marketing pitch is "below-market in-place," even when the comps supporting the market rent are thin. The broker excludes a management fee because the seller is owner-operated, even though the institutional buyer will hire a third-party manager at 3% of effective gross income on day one. The broker puts replacement reserves below the NOI line if they appear at all, because reserves drag NOI and drag the implied cap rate up. The broker scrubs the T-12 of any expense that looks non-recurring, including some that recur on a five-year cycle the buyer will see in year three. Each adjustment is defensible in isolation. Stacked, they produce an NOI 5–10% above what the institutional buyer will underwrite, and a cap rate 25–60 bps tighter than the buyer's IC will approve.

The institutional discipline is to ignore the broker NOI and rebuild from the rent roll and the T-12. This article walks the rebuild line by line: the five definitional differences that account for nearly the entire broker-vs-institutional gap, the cap-rate impact of each, the asset-class-specific conventions that change the conversation between multifamily and retail and office, and the T-12 normalization workflow that an acquisitions analyst runs on every deal. The pillar at/learn/cap-rate-calculator-and-formulacovers the cap-rate formula in which NOI is the numerator. The cap-rate decomposition article at/learn/cap-rate-decomposition-risk-free-premium-growthcovers the formula's components: risk-free rate, risk premium, growth. This article covers the numerator itself: which NOI is in the formula, and why two analysts citing the same cap rate may be valuing the same building at materially different prices.

NOI Basics: What's Included, What's Not

Net operating income (NOI) is the income a commercial real estate asset generates from operations, after operating expenses but before debt service, depreciation, income taxes, non-recurring capital expenditures, and corporate-level overhead. The short formula is:

NOI = Effective Gross Income − Operating Expenses

Effective gross income (EGI) is gross potential rent less vacancy and credit loss, plus other income (parking, laundry, storage, fees). Operating expenses include real estate taxes, property insurance, utilities not reimbursed by tenants, repairs and maintenance, on-site payroll, and property management. NOI is the property's operating cash flow before financing structure, before income tax structure, before non-cash accounting items like depreciation and amortization, and before non-recurring capital reinvestment. It is the number that goes into the cap-rate formula as the numerator, and it is the number every direct-capitalization valuation depends on.

Three line items are explicitly excluded from NOI by institutional convention. Non-recurring capital expenditures and corporate-level overhead are also outside NOI. The one capex-like item the institutional build deducts is the recurring replacement reserve, covered under difference 3 below.

• Debt service. NOI is unlevered. Mortgage interest and principal are below the NOI line. This is the answer to one of the most common search queries on the topic: "does NOI include debt service?" No. The whole point of NOI is to value the property's operating cash flow independent of how it is financed, so that two buyers proposing different capital structures can compare the same underlying number.
• Depreciation and amortization. NOI is a cash measure, not a GAAP earnings measure. Depreciation is a non-cash accounting entry that doesn't affect the property's operating performance, so it sits below the NOI line. "Does NOI include depreciation?" No.
• Income taxes. NOI is pre-tax. Income tax depends on the owner's structure (REIT, partnership, foreign investor) and is not a property-level cash flow. It sits below the NOI line in every standard institutional model.

The institutional debate is not about whether these items are included (the convention is settled) but about the treatment of the items that are in NOI: the management fee on an owner-operated property, the replacement reserves that some operators put above the line and some below, the non-recurring expenses in the T-12, the choice between in-place and market rents, and the vacancy assumption. These are the five definitional differences between a broker NOI and an institutional NOI, and together they explain nearly the entire gap.

Worth noting briefly: NOI is similar in construction to EBITDA. Both are pre-financing, pre-tax operating cash flow measures, but the two are not interchangeable. EBITDA is computed at the corporate level and includes property-level operating expenses plus corporate G&A; NOI is the property-level cash flow before corporate overhead is allocated. A REIT's portfolio EBITDA approximately equals the sum of its properties' NOIs minus its corporate G&A, before other income and expense items such as fee income and joint-venture results. The cross-walk is clean for single-property entities and gets noisy for diversified operators. For the cap-rate world, NOI is the number; EBITDA is the corporate cousin.

The Broker vs Institutional NOI Gap: Five Definitional Differences

The institutional NOI rebuild differs from the broker NOI in five specific places. Each one matters individually by roughly 0.5–8% of NOI; stacked, they add up to a 5–10% delta on stabilized assets and 10–20% on value-add. Each difference below is a convention choice: the broker isn't wrong, and the institutional isn't right; they are different conventions used by different audiences for different purposes. The institutional buyer needs the institutional convention because the buyer's underwriting, lender's DSCR sizer, and asset manager's monthly variance reporting will all be expressed in that convention. The broker's NOI was built to sell the property; the buyer's NOI will be lived with for the next seven years.

1. T-12 vs Pro Forma

Broker NOI is often "pro forma," the seller's projection of what the property will earn next year under market-rent assumptions, stabilized vacancy, and the seller's view of normalized expenses. Pro forma NOI is forward-looking. It assumes the property has finished its lease-up, that any below-market in-place rents have been marked to market, and that recent expense bumps were anomalous. The pro forma typically prints 2–8% above the T-12 trailing actuals for stabilized assets and 10–25% above for value-add or lease-up situations.

Institutional NOI starts from the T-12 actuals, the trailing twelve months of operator-reported (usually unaudited) income and expenses, exactly as they happened, without adjustment. The T-12 is the audit trail. The pro forma is a forecast. The institutional discipline is: build the underwriting NOI as T-12 actuals plus or minus specific, sourced, defensible adjustments. Mark-to-market rents only where 5+ recent comps support the mark. Strip non-recurring items only where the recurrence frequency is genuinely zero (not "this happened twice in five years, we'll call it non-recurring"). Normalize tax to budgeted reassessment only where the assessor's notice is in hand. The institutional NOI is reconstructable from the T-12 and the property accounting records; the broker pro forma usually isn't.

2. Market Rent vs In-Place

Broker NOI typically uses market rents on the rent roll. The pitch is "below-market in-place rents create immediate upside," and the OM's NOI bakes in the market-rent assumption. The seller's underlying logic may be sound: the property has 18% rent gain to market on lease rollover. But the broker's NOI captures that gain on day one, before the leases have actually rolled, and before the buyer has spent the year of operational work that the rollover requires.

Institutional NOI uses in-place rents from the rent roll, period. Mark-to-market adjustments are made transparently, separately, and only where the buyer has 5+ recent submarket comps within 6 months and 90–110% of the property's unit mix. The mark-to-market upside is then modeled as a Year 1–3 lease-up cash flow, not embedded in Year 0 NOI. The discipline matters because the cap-rate analysis uses Year 0 NOI as the numerator. Embedding mark-to-market upside in that number conflates the "what the asset earns today" with the "what the asset will earn after the buyer executes the rollover," and the two are different valuations.

3. Capex Reserves: Above or Below the NOI Line

Capital expenditures and replacement reserves are a frequent point of disagreement. The broker convention is typically to omit reserves from NOI entirely, or to mention them as a separate footnote below the NOI line. This makes the broker NOI larger and the implied cap rate tighter. The institutional build in this article puts recurring replacement reserves above the NOI line, deducted as an operating expense, so that NOI is a "true" cash flow that reflects the cost of maintaining the asset in its current operating condition.

Illustrative reserve standards: $250–400/unit/year for stabilized multifamily; $0.15–0.30/SF/year for anchored retail (excluding tenant-paid TI/LC); $0.20–0.40/SF/year for industrial; $0.50–1.00/SF/year for office (excluding TI/LC, which is separately below the line). Non-recurring capex (full roof replacements, major HVAC overhauls, renovation programs) sits below the NOI line in both conventions; the dispute is only over the recurring reserve component. A 240-unit multifamily with a $300/unit institutional reserve runs $72K below the broker NOI on this line item alone, about 2.5% of the worked example's $2,912,400 broker NOI.

Shops differ on where the recurring replacement reserve sits. Some report NOI before reserves and deduct reserves in a separate net cash flow line below NOI; others deduct them above NOI. Deducting above NOI produces the lower NOI and the wider cap rate, which is why this article uses it. Whichever convention you choose, apply it consistently across the deal model, the exit cap, and the comp set, and translate explicitly when comparing to outside sources.

4. Management Fee: Included Even When Owner-Operated

The broker OM for an owner-operated property typically excludes any management fee. The argument is that the seller is the manager, so there is no third-party fee to deduct, and the property's "true" NOI is what it produces without that deduction. The institutional convention disagrees on principle: NOI must be comparable across owner-operated and third-party-managed properties, so a market management fee is imputed regardless of the seller's operating structure.

Illustrative management fees by asset class: 2.5–3.5% of EGI for stabilized multifamily; 3.0–4.0% for anchored retail; 3.0–5.0% for office (varies with property complexity). For the 240-unit multifamily in the worked example, the imputed 3.0% management fee on $4,745,640 of institutional EGI is $142,369, a 4.9% NOI haircut relative to the broker's "owner-managed, $0" treatment and the largest single component of the gap.

The reasoning is structural. The institutional buyer is almost always going to engage a third-party manager, either immediately or within the first year. The buyer's underwriting must reflect that cost. Equally important, the buyer's eventual exit will be to another institutional buyer who will impute the same management fee in their underwriting, so the value at exit is the value of NOI net of management fee, not gross. The convention enforces that the NOI seen at acquisition equals the NOI seen at exit, holding management structure constant.

5. Non-Recurring Items: Stripped on Both Sides of the Ledger

The broker convention strips non-recurring expenses (storm damage, one-time legal settlements, deferred-maintenance catch-up) from the T-12 because they "don't reflect ongoing operations." This is correct in principle. The problem is that the broker also typically leaves in non-recurring income (lease termination fees, insurance settlements, retroactive tax abatements) because that income inflates NOI. The institutional convention strips both: non-recurring expenses are added back, non-recurring income is taken out. The expense add-back is common to both conventions, so the gap comes from the income that only the broker leaves in.

Worked example. A 240-unit multifamily in a Florida coastal submarket. T-12 actual operating expenses of $1,930,000 include a $43,000 storm-damage repair. T-12 other income of $285,000 includes a $30,000 lease termination fee from a corporate tenant that vacated three units mid-year. The broker NOI adds back the $43,000 expense ("non-recurring") but leaves the $30,000 fee in income ("part of operations"). The institutional build adds back the same $43,000 and removes the $30,000 fee. Against reported T-12 NOI, the broker NOI is up $43,000 and the institutional NOI is up $13,000 ($43,000 less $30,000). The broker NOI is therefore overstated by $30,000 relative to the institutional build, about 1.0% of broker NOI. The storm add-back explains none of the gap.

Storm damage, lease termination, retroactive tax abatement, a large prior-year invoice booked in the current year, a settlement payment from a defaulted tenant, environmental insurance proceeds: these are the non-recurring items that show up most often. The institutional discipline is to strip them on both sides and document the rationale per line. A spreadsheet trace from T-12 reported NOI to underwritten NOI, with each adjustment named and sourced, is the artifact the IC will require.

The 25-60 BPS Cap-Rate Impact: A $52M Multifamily Worked Example

The NOI gap matters because it moves the cap rate. At a 5% cap, a 5% NOI haircut at the same price is exactly a 5% value haircut, or, equivalently, a 25-bp cap-equivalent move at the original NOI. The math is simple and the institutional-discipline implication is large: two underwriters quoting "the same cap rate" on the same property may be valuing it 5–10% apart because their NOI conventions are different. The convention is the hidden variable that the cap rate alone does not surface.

The worked example: a hypothetical stabilized 240-unit Class B+ garden-style multifamily property in Tampa, marketed at $52.0M. The broker OM prints $2,912,400 of NOI for a 5.60% implied cap. The institutional rebuild produces $2,644,271 of NOI, a 9.2% haircut, and a 5.09% institutional cap on the same $52.0M price. The 52-bps gap comes from four conventions applied to the same T-12 base: vacancy, the lease termination fee, the management fee, and reserves. The example holds in-place rent and the T-12 expense base constant on both sides, so it does not show the T-12-vs-pro-forma or market-rent differences; an OM that uses them would show a wider gap.

Table 1: Hypothetical Tampa 240-unit multifamily, line-by-line broker vs institutional NOI rebuild at a $52.0M ask price. The $268,129 (9.2%) NOI haircut translates to a 51.6-bp cap-rate spread on the same price (5.60% × 9.2%), computed on unrounded caps. Illustrative assumptions, not a specific transaction.

A buyer who sees the broker's 5.60% cap and bids $52M is paying a price the buyer's own IC, applying the institutional convention, would describe as a 5.09% cap deal. The same underwriting team would, after the close, report monthly variances against an institutional-NOI budget that runs $268,129 below the broker's $2.91M number, meaning the deal will appear to be "underperforming pro forma" from month one when in fact the buyer is delivering exactly the operational performance the broker described, just in the buyer's own NOI convention. Misalignment of NOI conventions between the underwriting and the asset management team is a source of "broken" deals that aren't broken in any operational sense.

The discipline is to rebuild before bidding. The pocket model that runs this rebuild for institutional multifamily core is AQ-110; for anchored retail with its different reserve and recovery conventions, AQ-301; for industrial with its lower variability and different reserve standards,AQ-401.

Asset-Class-Specific NOI Conventions

The institutional convention is consistent in spirit across asset classes but differs in operational detail. Five asset classes carry conventions that the multifamily walkthrough above doesn't fully capture; each is worth a paragraph because the convention shapes the comparable cap analysis.

Multifamily

The convention covered in this article's worked example. Key sub-conventions: RUBS (ratio utility billing system) recoveries are typically treated as revenue, not as an offset to the underlying utility expense. This grosses up both EGI and OpEx by the recovery amount and leaves NOI unchanged before any percentage-of-EGI management fee (a 3% fee rises by 3% of the recovery). Concessions are netted against gross rent to arrive at effective rent; never above-the-line. Bad debt is included in vacancy and credit loss, not in OpEx. Illustrative replacement reserve standard: $250–400/unit/year, with the higher end for older Class B and B− properties and the lower end for newer Class A.

Anchored Retail

Retail NOI conventions hinge on the treatment of expense recoveries (CAM, real estate taxes, insurance, collectively "common-area maintenance" or NNN recoveries). The institutional convention is to "gross up" the income statement: include both gross expense reimbursements as revenue and the corresponding gross expenses on the expense side, so the recovery percentage and any leakage (unreimbursed common-area expense, vacant-space recovery shortfall) is visible. The broker convention is sometimes to "net" expense recoveries, which obscures the recovery leakage. NOI is the same either way before any percentage-of-revenue management fee, but the institutional discipline preserves the line-item transparency the asset management team needs for monthly reporting and recovery reconciliations. Illustrative replacement reserve standard: $0.15–0.30/SF/year; TI/LC is separately below the line.

Office

Office carries heavy TI/LC (tenant improvement and leasing commission) costs and the convention around TI/LC is firm: always below the NOI line, never inside operating expenses. This is structural. TI/LC is non-recurring per-lease capex, deployed at lease signing or renewal, with a multi-year amortization profile that doesn't fit the operating-expense rubric. Office NOI also tends to be more sensitive to non-recurring lease termination fees (which are stripped) and to retroactive recovery true-ups (which are stripped). Illustrative replacement reserve standard: $0.50–1.00/SF/year, excluding TI/LC.

Industrial

Industrial NOI is comparatively simple among the four major asset classes. Net lease structures (NNN or NN) shift most operating expense risk to the tenant, so the property-level NOI is closer to the gross rent than in other sectors. Tenant credit becomes a more dominant variable than operating expense management. The institutional convention adds a market management fee even on owner-operated, applies a smaller reserve ($0.20–0.40/SF/year) because the building has fewer wear-prone systems than multifamily or office, and strips non-recurring lease termination payments, which can be larger in industrial because the tenant is often a sole-occupier with higher individual termination economics. Vacancy assumption matters more than for multifamily because a single vacancy is a step function rather than a small percentage move.

Hospitality (briefly)

Hotel financials follow the Uniform System of Accounts for the Lodging Industry (USALI) rather than the cap-rate convention used by the four core CRE asset classes. The management fee, brand fee, and FF&E reserve are large explicit line items rather than the modest adjustments they are in multifamily. Hotel cap rates apply to NOI after the management fee and the FF&E reserve, so an earlier profit line such as "house profit" or GOP (gross operating profit) is not the number to capitalize. The institutional discipline of stripping non-recurring items and rebuilding from operator-reported P&Ls still applies; the line items differ.

T-12 Normalization: The Institutional Walkthrough

The actual workflow an acquisitions analyst runs on a deal, in order. Each of the ten steps takes roughly 3–10 minutes and references a specific source document. The artifact at the end is a one-page spreadsheet with reported T-12 NOI in the leftmost column, each adjustment named and quantified in the middle, and the underwritten NOI on the right. The trace is the audit. An IC submission without it is a submission without underwriting.

1. Pull the rent roll and the T-12 income/expense statement. Both are standard items in the institutional data room. Verify the rent roll's effective date is within 30 days; verify the T-12 covers a full twelve months and is reconcilable to the property accounting system (Yardi, RealPage, MRI). If either is materially older or incomplete, request fresh documents before underwriting further.

2. Build gross potential rent (GPR) from the rent roll. Per-unit, by floor plan, in-place rent on the contract. Total to a 12-month annualized GPR. This is the starting point: not the broker's market-rent GPR, but the in-place number that ties to the rent roll. For commercial leases, GPR is base rent plus contractual escalations applicable to the underwriting period.

3. Apply vacancy and credit loss. Use the conservative max of (a) the T-12 trailing vacancy and credit loss percentage and (b) the submarket average from CBRE, CoStar, or Yardi data. Illustrative ranges for stabilized deals are 5–7% for multifamily, 5–10% for retail, 8–15% for office, 3–7% for industrial. Document the source.

4. Add other income from the T-12. Parking, laundry, storage, application fees, late fees, pet fees, RUBS recoveries (gross). Strip non-recurring items: lease termination fees, insurance settlements, legal recoveries. Subtract the non-recurring income on a separate line so the adjustment is visible.

5. Rebuild operating expenses by line. Real estate taxes (rebuild from the assessor's notice if it is in hand, and from the expected post-sale assessment where a sale resets the assessment; otherwise T-12 actual); insurance (use the most recent renewal quote rather than the T-12 premium); utilities (T-12 actual, less any one-time spike); repairs and maintenance (T-12 actual, less identifiable non-recurring expense like the storm-damage example); on-site payroll (T-12 actual); property management (impute market 3% if owner-operated, otherwise T-12 actual); marketing and administrative (T-12 actual).

6. Strip non-recurring expenses. Storm damage, one-time legal settlements, deferred-maintenance catch-up, prior-year invoices booked in the current year. Each item named, dated, and supported by an invoice or a journal entry from the property accounting system. The "non-recurring" label without supporting documentation is an adjustment IC members will challenge.

7. Apply the management fee at market. Even if the property is owner-operated, and even if the seller insists no management fee should be deducted, impute the market rate (3% of EGI for multifamily, varies by asset class). The institutional comparability discipline requires it.

8. Deduct replacement reserves above NOI. $300/unit/year for multifamily core (use $250 for new Class A, $400 for older Class B−). Note the convention you're using; some shops report NOI before reserves and deduct them in a net cash flow line. Be consistent within the deal model and the exit-cap math.

9. Calculate underwritten NOI. The number after all adjustments above. Compare to the broker NOI. The gap should be 5–10% for stabilized assets, 10–20% for value-add. If the gap is materially smaller or larger, recheck the adjustment list: either the broker NOI is unusually institutional in its build, or your rebuild missed an adjustment.

10. Document the trace. The one-page spreadsheet from reported T-12 NOI to underwritten NOI, with every adjustment named, quantified, and sourced. This is the artifact the IC will review and the artifact the eventual exit broker will see when the asset is sold. The trace is the institutional discipline.

How to Model the Institutional NOI in Excel

The institutional NOI rebuild fits on a single Excel tab with the structure below. Layout matters because the tab will be reviewed by IC members and by the lender's debt analyst; the trace from T-12 reported to underwritten NOI should be readable in 30 seconds.

• Column A: Line-item name, in institutional standard order: gross potential rent, vacancy and credit loss, other income (with sub-rows for each component), effective gross income, operating expenses (sub-rows: taxes, insurance, utilities, R&M, payroll, management, marketing, admin), management fee imputation, replacement reserve, underwritten NOI.

• Column B: T-12 reported value from the property accounting system, exactly as it appears in the data-room T-12 file. This is the audit anchor.

• Column C: Adjustment amount (positive or negative), with the rationale in a comment on the cell. The adjustments are: non-recurring expense add-back, non-recurring income strip, vacancy normalization, tax reassessment normalization, insurance renewal normalization, management fee imputation, replacement reserve.

• Column D: Underwritten value: column B plus column C. This is the institutional NOI line in the cap-rate calculation.

• Column E: Source, meaning the document and page reference for the underlying value or the adjustment rationale. T-12 file page 4 for an expense item, rent roll for a GPR component, recent CBRE report for a submarket vacancy benchmark, county assessor notice for a tax reassessment.

The output cell is the underwritten NOI at the bottom of column D. Divide it by the property's asking price (or the buyer's bid price) to get the implied institutional cap rate. Compare to the broker quote and to recent transaction comps that use the same NOI convention. The pocket models referenced above implement this structure with the line items pre-populated for each asset class.

Common Mistakes

Seven errors that distort NOI rebuilds. At a 5–6% cap rate, every 1% of NOI error is roughly 5–6 bps of cap rate, so a 5% error is 25–30 bps when carried into a bid.

• Trusting the OM NOI without re-building T-12. A costly error in CRE acquisitions. The broker's NOI was built to sell the property, not to underwrite it. Even when the broker is honest about the conventions used, the broker's conventions are not the institutional conventions, and the gap is large enough to move bids by 5–10%. Always rebuild from the T-12 and the rent roll. The 30-to-100-minute discipline on a $52M deal pays for itself many times over.

• Treating "non-recurring" as the analyst's discretion. Strip a non-recurring item only with an invoice, a settlement document, or a journal entry that supports the rationale. "It looks non-recurring" without documentation is an adjustment IC members will challenge. If the item recurred even once in the prior 24 months, it is not non-recurring: it is part of the asset's operating risk and should stay in NOI.

• Marking rent to market on the rent roll without supporting comps. The mark-to-market upside belongs in a Year 1–3 lease-up model, not in Year 0 NOI. If you embed it in Year 0, your direct-cap valuation overstates the asset by the present value of the rollover, which the seller has already priced into the asking price. Pay for the asset twice and you've broken the deal economics.

• Omitting the management fee on an owner-operated property. The buyer will hire a third-party manager on day one or impute one for asset management reporting. The market management fee belongs in NOI, not below it. Owner-operated is an operating-structure choice, not a definitional NOI feature. Treating it as a definitional feature is the largest single component of the broker-vs-institutional NOI gap in the multifamily worked example above ($142,369 of the $268,129).

• Putting replacement reserves below the NOI line on a deal where comps put them above. The convention matters because the cap rate is computed on NOI; if the comp set deducts reserves above NOI, your deal needs to deduct reserves above NOI for the cap to be apples-to-apples. Some shops report NOI before reserves and deduct them below; others deduct above. Be consistent with the comp set you are pricing off.

• Failing to gross up RUBS recoveries on multifamily. The institutional convention is to show the recovery as revenue and the underlying utility expense in OpEx separately. Some operators net the two, which obscures the recovery percentage and any leakage. Net effect on NOI is the same before any percentage-of-EGI management fee, which rises with the grossed-up EGI; the line-item transparency matters for asset management reporting and for the comp analysis with properties that report gross.

• Ignoring the property-tax reset on a sale in Florida and Texas. In Florida, annual changes in assessed value for non-school levies on non-homestead property are capped at 10% (Fla. Stat. 193.1555(3)), but a sale resets the assessment to just value as of January 1 of the following year (193.1555(5) and (5)(b)). A seller who has held the asset for years can be paying tax on an assessed value well below what the buyer will be assessed, so the T-12 tax line understates the buyer's run rate. In Texas, the 20% circuit-breaker limit inTex. Tax Code 23.231applies only to real property appraised at not more than $5 million for the 2024 tax year, adjusted for CPI in later years (subsections (b) and (j)), so a $52M multifamily asset is not covered by that cap. Rebuild the tax line from the assessor's expected post-sale value and the millage rate, not from the seller's bill. Each $26,443 of added annual tax is 1% of the worked example's institutional NOI and about 5 bps of cap rate at the $52.0M price.
