Value-Add Multifamily: Renovation Premium Modeling for the 2026 Vintage

Key Takeaways

Why Renovation Premium Is the 2026 IRR Battleground

A value-add multifamily deal's levered IRR sits on three legs: the renovation premium the sponsor earns on the interior reposition, the market rent growth that compounds on top of it, and the exit cap rate that capitalizes everything into a sale price. The 2021–2022 vintage assumed two of those three legs. Sun Belt rents grew 17.8% in 2021 alone (Apartment List), and cap rates compressed into the high threes and low fours. The premium block was the easy lift; the tailwinds did the heavy work. The 2026 vintage inherits neither tailwind. Yardi Matrix projects asking rents grow just 0.5% nationally in 2026 (Multifamily Dive), and the Sun Belt submarkets that absorbed the most 2021–2022 capital are in contraction — Austin −4.3%, Denver −3.6%, Tampa −3.4%, Phoenix −2.7%, Raleigh −2.0%. Going-in cap rates for value-add multifamily printed 5.32% in Q1 2026 per the CBRE Multifamily Buyer and Seller Sentiment Survey, exit caps 5.42%. The premium block is now the entire return.

This article is the practitioner reference for the renovation-premium underwrite. It walks the cost-per-unit budget by improvement tier in 2026 dollars, the achievable rent premium by tier and submarket against a flat-to-negative rent backdrop, the absorption curve from renovation start to stabilization with the in-arrears realization discipline, the bridge from premium dollars to stabilized NOI, the exit-cap sensitivity that compounds every dollar of premium into capitalized value, and the 2021–2022 vintage IRR reset modeled on the same 200-unit Sun Belt deal in both vintage parameters. The reset is the centerpiece — the same physical asset, the same renovation scope, modeled twice, and the IRR delta tells the entire story of why the 2026 acquirer cannot underwrite the way the 2021 acquirer did.

The audience is value-add multifamily acquisitions teams (REPE associates, VPs, principals) building IC memos against an OM already in hand; sponsor GPs pricing renovation scope against the comp set; LP allocators reading a GP-underwritten premium and deciding whether to fund it; debt brokers underwriting bridge debt against the same renovation premium and absorption curve; asset managers executing against original underwriting; and the workout cohort — the 2021–2022 vintage GPs running maturity playbooks where the underwritten premium did not materialize and the bridge debt has tripled in cost. The math is the same in both directions: forward underwriting for the new acquirer, reverse engineering for the workout.

The Renovation Premium Chain

The renovation-premium block is six linked steps. Each one is a defensible numerical claim; if any one fails, the IRR breaks. Underwrite each independently, then chain them:

1. Renovation cost per unit by tier. What the interior reposition costs in 2026 dollars — light-touch refresh, classic value-add, or heavy-lift unit reposition. Sourced against RS Means construction cost data, current debt-fund construction-loan diligence comps, and verifiable contractor bids.

2. Achievable rent premium by tier. What the comp set will pay for the renovated unit, in absolute dollars per month. The premium has to be defensible against (a) comp rents within a half-mile radius, (b) the submarket's current rent-growth trajectory, and (c) the supply environment. A 12–15% Class B premium is the institutional benchmark (Leni internal data, Multi-Housing News) — tier and market dispersion is wide.

3. Absorption curve. The schedule on which renovated units actually come online and start producing the premium — 10 units/month is the classic pace, 30–60 days of vacancy per turn, 12 to 24 months to stabilization on a 200-unit deal. Tactica RES's framing is correct: premiums are paid in arrears.

4. Stabilized NOI build. Premium dollars × units × occupancy × 12 months, less the OpEx delta from tax reassessment and incremental insurance, plus the R&M tailwind from new finishes. The OpEx delta is where careful underwriters and careless ones diverge by 5–10% of stabilized NOI.

5. Exit cap rate. The single-biggest IRR destroyer. CBRE's Q1 2026 value-add exit cap printed 5.42%; a 50 bps swing changes a 16% underwritten IRR by 400–500 bps. The renovation premium creates the value; the exit cap capitalizes it.

6. Capital stack and bridge cost. Floating-rate bridge debt at SOFR +350–450 in 2026, with rate-cap renewal exposure (see Bridge Loans: Floating-Rate Risk, Rate Caps, and the 2026 Exit Assumption), is the leverage engine that amplifies the renovation premium — or, in the 2021–2022 case, the engine that destroyed the equity when the premium did not materialize on schedule.

The Three Tiers and What They Cost in 2026

Institutional value-add multifamily renovations fall into three operating tiers. The tier is set by the gap between in-place rents and submarket rents, the physical condition of the asset, and the sponsor's hold horizon. The dollar ranges below reflect 2026 institutional construction cost data triangulated from RS Means, current debt-fund construction-loan diligence comps, and published renovation budgets from Smart Build NE, Lloyd Jones, Fincor, and the Lessen 2026 Renovation Forecast. The 2024–2025 inflation overlay pushed budgets 20–30% above 2021–2022 underwriting assumptions; 2026 is forecasting low-single-digit additional growth.

Table 1 — Renovation tier taxonomy. 2026 dollar ranges. Cost-per-unit excludes common-area / exterior capex; add $1,500–$3,000/unit equivalent for amenity package, paint, signage, lighting, and landscaping on a typical garden-style asset.

Tier selection is the first underwriting decision and the most consequential one. A light-touch refresh on an asset that the submarket has already absorbed at the in-place rent will not generate enough premium to clear the bridge debt service; the deal is mispriced. A heavy-lift reposition on an asset where the submarket comp set tops out at $200–$300 above in-place rents will overspend the renovation budget against an unachievable premium. The most disciplined sponsors size the tier to the gap, not the inverse.

Material and labor inflation through 2024–2025 reset the baselines. A "$10K/unit classic value-add" in 2021 underwriting is $12–15K/unit in 2026. The line items that moved most were appliances (refrigerators, in-unit laundry), LVP flooring (post-2022 tariff cycle), and rough plumbing/electrical labor in the Mountain West and Sun Belt where multifamily delivery cycles compressed contractor availability. Heavy-lift scopes that touch electrical panel or HVAC equipment moved the most — mechanical labor in particular has compounded above the construction average. 2026 forecasts low-single-digit additional growth in materials and 3–5% in skilled trades.

Regional cost dispersion matters. The same classic value-add scope runs $9–11K/unit in non-coastal Sun Belt metros, $12–14K/unit in mid-Atlantic and Mountain West, and $14–17K/unit in the Northeast and coastal California. Sun Belt cost advantage was a 2021 underwriting assumption that has narrowed materially — trade availability in Phoenix, Tampa, and Charlotte has tightened against the delivery pipeline. A cost-per-unit input that uses a national average rather than a submarket-specific number is a common error in OM-stage underwriting.

Achievable Premium by Tier and Submarket

The achievable rent premium is the most contested input in the value-add stack. The institutional benchmark cited by Leni is a 12–15% rent premium on Class B renovations in key markets. By tier in absolute dollars: light-touch $50–100/mo, classic value-add $125–225/mo, heavy lift $200–350/mo. The dispersion is submarket-specific and tier-specific, and in 2026 the dispersion is wider than it was in 2021 because the underlying rent-growth environment has bifurcated.

Table 2 — Achievable rent premium by tier and submarket cohort, 2026 underwriting environment. Triangulated against Yardi Matrix submarket rent reports, CoStar Class B/C comp data, and sponsor underwriting comps observed in 2025–2026 OMs. Sun Belt contraction markets reflect Yardi Matrix's negative trailing-twelve rent prints.

The Sun Belt contraction cohort is the underwriting story of 2026. Per Multifamily Dive reporting Yardi Matrix data, asking rents across the highest-supply Sun Belt submarkets are running negative on a trailing-twelve basis — Austin −4.3%, Denver −3.6%, Tampa −3.4%, Phoenix −2.7%, Raleigh −2.0%. National rent growth is forecast at +0.5% in 2026, +1.0% in 2027, +2.3% in 2028. The premium math has to work against a flat-to-negative submarket baseline, not the 5–10% underwritten rent-growth tailwind that animated 2021–2022 deals.

This is the defensibility question. A 2021 underwriting that priced a $200/mo classic value-add premium in Austin was implicitly priced against a 10%+ rent-growth tailwind — the premium plus the market lift together cleared the IRR. In 2026, the same $200/mo premium in Austin has to clear the IRR with the market pulling against it. The premium has to be defensible on renovation merit alone — the renovated unit must rent at $200/mo above the in-place rent because the finishes are demonstrably better than the comp set, not because the market is lifting the comp set on a tide.

A note on the RealPage settlement (November 2025): revenue-management tools that integrate competitor pricing data can no longer use real-time competitor data; pricing recommendations must rely on data at least 12 months old. The operational consequence is that comp-set data is now staler than the deal cycle on which a sponsor is underwriting. The rent-comp defense workflow has gotten harder, not easier — manual comp validation and broker-side rent surveys are recovering relevance.

The Absorption Curve and the In-Arrears Reality

The single most common error in value-add multifamily underwriting is treating the renovation premium as a step function — on Day 1 the asset rents at the in-place rent, on Day 366 it rents at in-place plus the underwritten premium. The actual realization curve is a 12–24 month tail, and the IRR is materially sensitive to the shape of the tail. As Tactica RES frames it: renovation premiums are paid in arrears.

Consider a 200-unit garden-style deal on a classic value-add schedule. The acquisition closes in month 0. The sponsor and construction manager spend months 1–3 on permits, contractor selection, materials sourcing, and a small pilot block (10–20 units) to validate the scope and the achievable premium. Production renovation pace begins month 4 at a typical 10 units/month — faster pace is possible with multiple crews but elevates downtime risk if leasing can't keep up. At 10 units/month, the full 200-unit lift takes 20 months of production, plus the 3-month mobilization, for a 23-month renovation block. Lease-up of the final cohort extends another 4–6 months, putting full stabilization at month 28–30.

Table 3 — Absorption curve for a 200-unit classic value-add at 10 units/month renovation pace. The full stabilized run-rate is achieved in month 29, not month 12. Loss-to-lease during the renovation block and lease-up concessions are real cash drags — underwrite them.

The downtime per unit is the bridge between renovation pace and realized premium. A classic value-add turn that requires the unit to be vacated runs 30–60 days of vacancy from tenant move-out to first day of new lease — tear-out, materials staging, installation, inspection, punch list, marketing, application, lease-up. At 50% occupancy-during-renovation (a common operating assumption) the sponsor loses roughly $700–1,200 of rent per turn at typical in-place rents. On 200 units that is $140–240K of pre-stabilization loss-to-lease that has to be funded out of operating cash or the bridge interest reserve.

Concessions during lease-up are the other in-arrears reality. Per Northmarq's market research, concession use in 2025–2026 lease-up has elevated meaningfully against the 2020–2022 trough. One-month-free is the baseline; two-month-free is observed in supply-heavy Sun Belt submarkets. On a $1,800/mo renovated rent, a one-month concession is a 8.3% net-to-asking discount that the underwriting typically does not headline. The effective realized premium in the first lease cycle is 8–16% below the underwritten asking-rent premium. Burn the concession off in the model over the first 12–18 months of stabilization.

From Premium Dollars to Stabilized NOI

The premium-to-NOI bridge is mechanical but it has three line items underwriters miss. Start with the gross premium contribution at stabilization. A $200/month/unit premium × 200 units × 12 months × 95% economic occupancy = $456,000 of incremental top-line in steady state. From that, three OpEx adjustments:

• Real estate tax reassessment. The property's taxable basis reassesses on the sale and on the post-renovation value uplift. In jurisdictions that reassess on sale (most Sun Belt states), the new basis is the acquisition price; the underwriting needs to size taxes at the new basis from year 1, not at the prior owner's stale assessment. On a typical 200-unit Sun Belt deal acquired at $50M with prior taxes running $400–500K, the post-acquisition tax bill is often $700–900K — a $250–500K/year OpEx step that erodes a measurable portion of the premium contribution.

• R&M trajectory. Renovated units carry lower routine R&M cost for the first 3–5 years post-renovation — new finishes, new appliances, new flooring don't fail at the same rate as the prior condition. The R&M tailwind is often $50–100/unit/year for the first three years before reverting to the new normalized run-rate. The disciplined model captures this but doesn't extrapolate it permanently — underwriting a $100/unit/year R&M savings into the residual cap rate calculation is an aggressive move that exit appraisers will discount.

• Insurance on the uplifted replacement cost. Property insurance has compounded 15–25%/year through 2023–2025 in Sun Belt wind/hail markets and is showing similar 2026 trends. A renovated asset has a higher insurable replacement cost and higher schedule values, marginally raising premium independent of the market trend. Underwrite insurance with the market trend baked in; the 2021 practice of holding insurance flat at the in-place expense ratio was a structural error.

Table 4 — Premium-to-NOI bridge on a 200-unit Sun Belt classic value-add. $200/mo premium × 200 units × 12 × 95% = $456K gross premium contribution. Net NOI lift, after OpEx delta, is $278K — roughly 61% of the gross premium dollars flow to NOI on a typical Sun Belt deal in 2026.

The value-on-cost math is where the premium block pays off — or doesn't. $278K of incremental NOI capitalized at a 5.50% exit cap is $5.05M of incremental capitalized value. Against $12K/unit × 200 units = $2.4M of renovation capex, the premium block is a 2.1x value-on-cost multiple. Above 2.0x, the renovation underwrites cleanly. Below 1.5x, the deal is too thin to absorb any execution variance. A typical institutional threshold is a 1.75x value-on-cost minimum at the underwritten exit cap; at a stressed exit cap (the same deal at 6.00%) the multiple compresses to 1.93x, still cleared.

Cross-link: the IRR machinery that turns this NOI build into a levered return is IRR Sensitivity Analysis and Stress Testing. The exit-cap sensitivity below is the same input that drove the 2021–2022 vintage outcome.

Exit Cap, IRR Sensitivity, and the 2026 Cap Environment

The exit cap rate is the most consequential single input in any value-add multifamily IRR. The renovation premium creates the NOI lift; the exit cap capitalizes that lift into a dollar sale price. A 50 bps swing in exit cap on a 200-unit Sun Belt deal moves levered IRR by 400–500 bps. Per the CBRE Multifamily Buyer and Seller Sentiment Survey Q1 2026, value-add going-in cap rates printed 5.32% (+7 bps QoQ), exit cap rates 5.42% (+3 bps), and the value-add unlevered IRR target 9.81% (+2 bps). The spread between going-in and exit (10 bps) declined for the second consecutive quarter — the institutional view of trough cap rates is firming.

Cross-reference: Cap Rate Calculator and Formula for the underlying mechanics. The IRR-sensitivity table below assumes a 200-unit Sun Belt classic value-add at $50M acquisition, $2.4M renovation capex, $278K stabilized NOI lift, 18-month renovation block, 60% LTC bridge financing at SOFR +350, 5-year hold.

Table 5 — Exit cap sensitivity on the 200-unit Sun Belt deal. A 75 bps swing from 5.25% to 6.00% takes levered IRR from 15.6% to 9.5% — a 610 bps swing on a 50 bps cap-rate move. The 2021–2022 vintage underwrote exit caps in the 4.50–5.00% range; the 2026 actual is 5.42%.

The submarket cap-rate dispersion is wider than the national CBRE print suggests. Per Multi-Housing News quarterly market data, Washington D.C. value-add cap rates are running 5.50–5.75%; Atlanta infill value-add 4.50–5.00%; Phoenix and Austin value-add 5.50–6.25%; secondary Midwest 5.75–6.50%. A national average of 5.42% does not underwrite a Phoenix deal at 6.00%. Sponsor-specific exit-cap reads from the brokerage community on the asset's specific submarket are what should populate the model — not the survey average.

The 2021–2022 Vintage IRR Reset

This is the section. The same physical asset, modeled in 2021–2022 vintage parameters and in 2026 vintage parameters. The IRR delta is the entire story of why the 2026 underwriter cannot use the 2021 playbook — and why the 2021–2022 vintage workout cohort is the largest single source of multifamily distress underway through the 2026 maturity wall. Per the MBA CREF Forecast (February 2026), commercial and multifamily originations are projected to grow 27% to $805B in 2026, with multifamily originations to $399.2B from $330.6B. 17% of CRE and multifamily balances mature in 2026 — the largest maturity year on record. The 2021–2022 vintage is the bulk of that maturing balance.

Take a 200-unit Sun Belt garden-style asset. Built 2002, in-place rents $1,600/unit, in-place NOI roughly $2.30M. The asset is the same in both vintages — same units, same site, same physical condition. What changes is the underwriting environment.

Table 6 — The 2021–2022 vs 2026 vintage IRR reset. Same physical asset, same renovation scope, same underwritten premium. The IRR delta is the combined effect of cap-rate expansion, renovation cost inflation, bridge debt repricing, LTC compression, and the elimination of the rent-growth tailwind.

Five forces compound to produce the 790 bps reset. (1) Acquisition cap-rate expansion of 107 bps means the same in-place NOI buys 20% less basis, but cost inflation has eaten into the discount. (2) Renovation cost inflation of 25% adds $500K of capex on a deal that has less debt capacity. (3) Bridge debt at 8.30% all-in vs 3.30% all-in is roughly $1.2M of additional debt service over a 24-month bridge period — on a deal where the underwritten premium contributes $278K of incremental NOI, that interest delta consumes more than four years of premium contribution. (4) Loan-to-cost compression from 75% to 65% means the sponsor contributes an additional $4–5M of equity, which dilutes the IRR even if the deal otherwise performs. (5) The 2021 underwriting assumed +5%/year market rent growth would compound on top of the renovation premium, a tailwind that produced an additional $80–100/unit/month of organic rent uplift over the hold. The 2026 underwriting assumes the +0.5%/+1.0%/+2.3% Yardi forecast, which is roughly a quarter of the 2021 assumption.

The workout cohort math is the same, in reverse. A 2021 acquirer who bought at 4.25%, financed at SOFR +350 when SOFR was 0.05%, and modeled a 17.4% IRR exit at a 4.75% cap is in 2026 staring at: bridge debt service that has tripled because SOFR moved 450 bps and the rate cap renewal cost 5–10x the original, an exit cap that has expanded 75–100 bps below the underwritten exit, and a premium achievement that is short the rent-growth tailwind. The same deal that underwrote to 17.4% is exiting at a single-digit IRR or worse — and that is before any operating shortfall on the premium itself. Per NCREIF's NFI-CEVA (Closed End Value Add) vintage fund index, the 2021 and 2022 vintage funds are tracking materially below their underwritten returns — the data is subscription-gated, but the directional finding is well-publicized in trade press.

The maturity wall is the forcing function. The MBA CREF Forecast notes 17% of CRE and multifamily balances mature in 2026 — the largest single maturity year on record. The bulk of the multifamily slice is 2021–2022 vintage bridge debt that cannot refinance into permanent debt at clean LTV. See Bridge Loans: Floating-Rate Risk, Rate Caps, and the 2026 Exit Assumption for the debt-side workout mechanics — the four-exit waterfall, the rate-cap renewal economics, and the refinance gap math that determines whether each maturing deal extends, sells, or goes to workout.

Rent-Comp Defense in 2026

The rent-comp defense is the operational expression of the entire underwriting case. With Yardi Matrix forecasting +0.5% national rent growth for 2026 and Sun Belt submarkets in contraction, the underwritten premium has to clear the comp set on renovation merit alone — no tailwind, no benefit of doubt. The practitioner workflow has six steps and they have to be honest:

• Identify the post-2024 renovated comp set within a half-mile radius. The relevant comps are units that have been renovated to a comparable scope in the trailing 18–24 months. Pre-2022 renovated comps are stale because the comp set has had two cycles of new deliveries enter the submarket. Pull from CoStar Class B/C comp data, Yardi Matrix submarket reports, and broker-side rent surveys; the post-RealPage settlement environment has made revenue-management-tool data less actionable.

• Build the trailing 90-day asking-rent trajectory for the comp set. Are the comps flat, contracting, or growing? In Austin, Phoenix, Tampa, Denver, and Raleigh the answer is contracting — and the comp-set trajectory has to be reflected in the underwriting rather than averaged away to a national flat baseline.

• Net concessions against asking. One-month-free is roughly 8% off asking; two-month-free is 16%. The effective realized rent at the comp set is what the renovated asset will compete against, not the gross asking. The Northmarq research on the concessions overlay is the citation.

• Lease velocity and days-on-market. A comp set that prices well but leases slowly is a soft market. Stress the absorption curve longer; budget more concession.

• Pipeline of new deliveries. A submarket with 5,000 units of new supply delivering through the renovation period faces additional pricing pressure. Renovated Class B units compete with new Class A product at the rent strata where the premium lives.

• The retention overlay. Premium underwriting is typically priced on new-lease economics, but on a 200-unit deal the sponsor is not renovating all 200 units at once — some are turning over organically into rented condition. Tenant retention on the non-renovated units during a renovation block often drops 5–10 points because the construction disruption pushes good tenants to leave. The retention drop has to be in the model.

The most disciplined institutional acquirers in 2026 are pricing premium at 70–80% of the comp-set achievable premium on the assumption that 20–30% of underwritten premium does not realize on schedule. A $200/month underwritten premium becomes a $140–160/month base-case in the IC memo, with the upside case at the full $200. The downside case strips the premium further and stresses the absorption curve. The sponsor that gets the deal at the most aggressive premium underwriting in 2026 is, with high probability, the sponsor that will end up in workout in 2029.

From Renovation Pro Forma to Institutional Underwrite

The 2026 vintage discipline is not complicated. It is the 2021 playbook with the rent-growth tailwind removed, the renovation cost inflation baked in, the bridge debt cost priced honestly, and the exit cap stress widened. The same renovation-premium chain that earned a 17.4% IRR in 2021 earns a 13–15% IRR in 2026 if it is underwritten without tailwind assumptions and executed cleanly. That is still a clearing return for most institutional LP minimums — the value-add window did not close, the tailwinds did. The Origin Investments 2026 multifamily outlook argues the window is in fact reopening — supply is declining into 2027, demand is robust, the institutional capital that left the asset class in 2023–2024 is returning.

The institutional underwriting checklist is short. Premium achievement on renovation merit alone, no rent-growth assumption beyond the Yardi Matrix submarket forecast. Stress the premium to 70–80% of underwritten achievement in the IC downside case. Stress the exit cap to +50 bps. Stress the renovation budget to +15%. Stress the absorption curve to a 30-month tail. Build the floor-IRR scenario where all four stresses hit, and check it against the LP minimum. If the floor-IRR clears, the deal is underwritable.

The transition from renovation pro forma to institutional underwrite is two steps. The first is the screening pass — given the OM on the desk, given the comp-set rents, given the asset's submarket and the current cap-rate environment, does this deal plausibly clear the IRR floor? The second is the full pro forma — given the comp set, the absorption schedule, the OpEx delta, the exit-cap sensitivity, the bridge debt sizing, and the LP-level waterfall all wired, what is the underwritten and the stressed IRR? The screening pass takes minutes; the full pro forma takes days. The Apers products are built to compress both.

Six Mistakes Value-Add Underwriters Make

• Treating the renovation premium as a step function. The premium realizes in arrears over a 12–24 month tail, not on Day 1. Modeling the full premium from month 1 overstates the year-1 NOI by $200–400K on a 200-unit deal and inflates the IRR by 100–200 bps. Walk the absorption curve unit-by-unit; model the concession burn-off explicitly.

• Conflating premium achievement with market rent growth. The 2021 underwriting habit of applying a single rent-growth assumption to both the in-place rents and the renovated rents double-counted tailwind. In 2026, the disciplined model holds the renovation premium constant in real dollars and applies the Yardi Matrix submarket-specific rent-growth forecast to both rents separately. The renovation premium does not compound; the market growth does.

• Using a national renovation-cost average. Sun Belt cost advantage has narrowed against the mid-Atlantic and Mountain West; Northeast and coastal California are materially higher than the national midpoint. A national $12K/unit assumption on a Phoenix deal where the actual contractor bid will come in at $11K is conservative; on a D.C. deal where the bid will come in at $14–15K it is structurally wrong. Sourcing 2–3 contractor bids before final OM submission is the institutional standard.

• Not reassessing taxes on the post-sale basis. In jurisdictions that reassess on sale, the new property tax bill steps up materially — often $200–500K/year on a 200-unit deal. The 2021 habit of underwriting taxes off the prior owner's stale assessment was a structural error that compounded with the cap-rate expansion to amplify the IRR reset.

• Modeling the bridge debt cost statically. Bridge debt at SOFR +350 reset against a SOFR forward curve, not a point estimate. Sponsors who held SOFR flat at the acquisition print missed the 500 bps move that defined the 2021–2022 cohort. The model should run SOFR as a forward curve and check the IRR sensitivity to a +/−100 bps shift in the SOFR path.

• Pricing the rate cap as a one-time cost. The cap is required for the initial bridge term and again on extension. The renewal cap at current pricing can cost 5–10x the original cap. A model that does not have an explicit cap-renewal line item is mispricing the all-in debt cost by 25–75 bps. See Bridge Loans for the cap-pricing detail.
