The Debt Yield That Isn't Comparable: Why Lenders Recast In-Place NOI for Free Rent, Abatement Burn-Off, and Below-Market Leases—Before Setting Proceeds

A property with 94% physical occupancy and $2.1 million in trailing twelve-month NOI looks stabilized on the surface. The debt yield math appears straightforward. Then the lender's underwriting team pulls the lease schedule and begins the forensic work: identifying free rent periods that expire, rent abatements burning off, and rents sitting below replacement cost. What emerges is not the property the sponsor is selling, but the property the lender is actually lending against. This is the recast.

The recast is the invisible edit that precedes all debt sizing. It separates the sponsor's story from the lender's thesis. It is where institutional rigor meets sponsor optimism, and optimism loses.

The Free Rent Trap: Income That Isn't There Yet

Free rent is a leasing concession masquerading as occupancy. A tenant signs a three-year lease with months one through three free and months four through thirty-six at market rent. The property reports 100% occupancy. The sponsor's NOI includes the rent from months four onward. But the lender sees the lease differently: the tenant's actual economic commitment is spread across thirty-six months, not thirty-three. The effective rent is lower than the stated rent by the quantum of the free-rent value.

Lenders recast by either (a) amortizing the free rent across the lease term to establish the true economic rent, or (b) underwriting only the rent that is actually being paid in the stabilization period. The first method is mathematically cleaner. The second is psychologically conservative and more common in transitional underwriting.

The difference is material. A property with $2 million in trailing rent, but $200,000 embedded in free-rent concessions, has effective rent of $1.8 million. If the lender is underwriting a five-year hold, and the free rent burns off in year one, the NOI step-down in year two becomes a covenant risk or a refinance wall. The lender accounts for this by reducing the stabilization NOI assumption to reflect the normalized rent, not the headline rent.

Sponsors often resist this. They argue that free rent is temporary, that the tenant is locked in, that rent will be stable thereafter. The lender's response is clinical: "We are not underwriting your lease. We are underwriting our collateral's ability to service debt through a refinance or extension. If your refinance assumption depends on rent that does not yet exist, we reduce our proceeds to you today."

The Abatement Burn-Off: Income Cliffs and Extension Risk

Rent abatement is a landlord's agreement to reduce or suspend rent for a defined period, typically in exchange for tenant capital or as a concession during lease renewal. Unlike free rent, abatement often occurs mid-lease or at renewal, making its burn-off date more visible and its impact on debt service more acute.

A property with an abatement expiring in month eighteen of a five-year hold creates a cliff. The lender must ask: will the tenant renew at market rent when the abatement expires? Or will the tenant vacate, forcing the landlord to re-lease at a concession to fill the space? The lender does not assume the former. The lender assumes the latter or models a range and takes the haircut.

The recast here is twofold. First, the lender adjusts the in-place NOI to exclude the abated rent. Second, the lender models the renewal or re-lease scenario and stress-tests the debt service against the downside case. If the property has multiple abatements staggered across the hold period, the cumulative effect can render a seemingly stabilized asset into a serial refinance risk.

Extension lenders are particularly sensitive to this. A bridge loan maturing in thirty-six months, with abatements expiring in months twenty and thirty-four, leaves little room for tenant turnover, re-leasing, and rent recovery. The lender may impose a reserve or reduce the advance rate to reflect the duration mismatch between the loan term and the lease stability.

Below-Market Rents: The Renewal Penalty

Below-market rent is perhaps the most insidious form of embedded concession. The tenant is paying rent today, occupying space, and showing up in the occupancy number. The rent is real. But it is below what the market would pay for comparable space, and it will be below what the lender assumes the property can achieve at renewal.

Lenders identify below-market rents through rent comps, market surveys, and comparison to the property's in-place rents on other floors or wings. A Class B office building with in-place rent ranging from $28 to $38 per square foot, and a 10,000 square-foot block at $22 per square foot, has a below-market tenant. That tenant's rent will reset at renewal, and the lender must decide whether to assume renewal at market ($32 per square foot, say) or to assume a renewal at a discount to market ($28 to $30 per square foot) to account for tenant stickiness and re-leasing friction.

The recast adjusts the stabilization NOI to reflect the lender's assumption about what rent the property will actually generate at renewal. If the lender assumes $28 per square foot, the in-place NOI is reduced by the gap between the below-market rent and the normalized assumption. This is not a haircut on the sponsor's numbers. It is the lender's forecast of what the property will actually produce.

For sponsors holding through lease expiration, this matters less. For sponsors planning to exit or refinance before renewal, it matters enormously. The lender's debt sizing is based on the lender's rent assumption, not the sponsor's. If the sponsor's exit plan depends on the property achieving market rent at renewal, and the lender has assumed a 300-basis-point discount to market, the proceeds will reflect the lender's assumption, not the sponsor's thesis.

The Recast as Proceeds Discipline

The recast is not a negotiation. It is the lender's translation of the sponsor's income statement into the lender's underwriting language. It reflects the lender's view of what rents will actually be paid, when they will be paid, and what the property will refinance for if the sponsor cannot perform.

Proceeds are set based on the recast NOI, not the as-reported NOI. A $2.1 million in-place NOI that resets to $1.85 million after adjustments for free rent, abatement burn-off, and below-market assumptions produces a different debt service calculation and a different advance rate. The sponsor who did not anticipate this recast arrives at closing expecting $5 million in proceeds and receives $4.2 million instead.

The recast is also where lenders defend their thesis to their credit committees and to their investors. The lender's underwriting memo will detail each adjustment, the rationale for each assumption, and the sensitivity of the debt service calculation to changes in rent assumption. This discipline is what separates institutional lenders from those who chase yield without understanding what yield they are actually getting.

What I'm watching next

• Lease schedules with multiple staggered expirations and abatement burn-offs in 2025 and 2026, particularly in office and retail, where refinance spreads have widened and tenant credit has deteriorated. Lenders will be more conservative in assuming renewal rent.
• Sponsor refinance plans that depend on rent growth or lease-up assumptions that lenders view as optimistic. The gap between sponsor thesis and lender recast will determine whether a refinance happens on time or becomes a painful extension negotiation.
• Transitional deals where the sponsor is marketing "stabilized NOI" but the lender's recast reveals that 25% to 35% of that NOI is dependent on free rent burn-off or lease renewals at aggressive assumptions. These will be the refinance casualties of 2026.
