What Is Debt Yield in Commercial Real Estate?

You size a commercial real estate loan the way everyone is taught: run the loan-to-value, run the debt service coverage ratio, and arrive at a number you are confident in. Then the term sheet comes back lower — sometimes much lower — and neither of the two metrics you ran explains why.

The culprit is usually debt yield. It is the third constraint most borrowers never model, and on the wrong deal it is the one that quietly sets your proceeds. Worse, it does not move for any of the reasons LTV and DSCR move, so the levers you would normally pull do nothing.

This is especially true on CMBS deals, where debt yield is not a sanity check but the headline test. A borrower who sized a deal on a 75% LTV and a 1.25x coverage ratio can still be told the loan is $4 million short — because the debt yield came in under the lender's floor.

What debt yield actually is

Debt yield is net operating income divided by the loan amount, written as a percentage.

Debt Yield = NOI ÷ Loan Amount

A property generating $1,200,000 of NOI against a $12,000,000 loan has a debt yield of 10.0%. That is it. There is no interest rate in the formula, no amortization schedule, and no appraised value. It answers one blunt question for the lender: if I foreclosed tomorrow and took the building's income, what unlevered return would I earn on the money I lent?

Why it is immune to rate and amortization games

This is the property that makes lenders trust it. Both of the metrics borrowers usually rely on can be flattered without the deal actually getting safer.

Debt service coverage improves if you negotiate a lower rate or stretch amortization from 25 to 30 years, because the annual payment shrinks. Loan-to-value improves if the appraisal comes in high. Neither change puts a single extra dollar of income into the property.

Debt yield refuses to play. Because it only looks at income over loan balance, a lower rate, a longer amortization, and a richer appraisal all leave it untouched. The only two ways to raise debt yield are to increase NOI or to borrow less. That rate-proof quality is exactly why CMBS lenders lean on it: a loan that gets securitized and sold to bond investors needs a measure that cannot be engineered at the closing table. The Commercial Real Estate Finance Council (CREFC) codifies this logic in its CMBS market standards specifically because debt yield survives rate cycles without adjustment.

How it differs from DSCR and LTV

Think of the three as answering different questions. LTV asks how the loan compares to the asset's value. DSCR asks whether this year's income covers this year's payment. Debt yield asks how the loan compares to the income itself, with financing terms stripped out.

That is why two deals with an identical 1.25x DSCR can have wildly different debt yields — one financed at 5% over 30 years, the other at 7% over 25 years. The coverage ratio looks the same; the underlying income cushion does not.

CMBS and the 10% floor

Conventional banks often accept a debt yield of 8–9%. Fannie Mae and Freddie Mac multifamily programs sit in a similar band. CMBS lenders typically draw the line at 10% or higher, because their loans are non-recourse, pooled, and difficult to restructure once sold. The higher floor is the price of that structure — see what is a good debt yield for the full range by lender type.

Office and transitional retail now frequently face floors of 11%–13% or more. This is not arbitrary. Lenders are pricing tenant-rollover risk directly into the income floor so that if a major anchor departs after closing, the remaining NOI still justifies the loan balance.

The deal that looked beautiful until it did not

A Class-A multifamily acquisition in a coastal market: sub-4% cap rate, 65% LTV, DSCR clearing 1.25x with room to spare. The term sheet came back short — nearly $4 million short. The CMBS lender had a hard 8.5% debt yield floor. The property's NOI divided by the requested loan produced 7.2%. The lender did not care about the strong LTV or the pristine coverage; they capped proceeds strictly to hit the floor. The borrower faced an unexpected equity gap days before closing, could not raise the cash, refused preferred equity priced at a punishing rate, and walked — losing hard earnest money.

That is the deal that looked beautiful on every metric that borrowers model and failed on the one they skipped.

What the term sheet does not always tell you

Most write-ups on debt yield treat the loan amount as a single number. On bridge and construction deals, it often is not. A lender may advance $10M upfront and hold back $2M for renovations. The As-Is Debt Yield is calculated on the $10M initial advance against today's NOI. The Stabilized Debt Yield is calculated on the full $12M total commitment against projected stabilized NOI. Both have to clear the lender's floor. A deal that passes As-Is but fails Stabilized — or vice versa — does not close at the requested amount.

Loan sizing uses all three at once

In practice a lender runs LTV, DSCR, and debt yield together and lends the smallest result. The constraint that produces the lowest maximum loan is the binding one — and it is the only limit that actually determines your proceeds. The CRE loan sizing calculator runs all three at once.

Consider a $2,000,000 NOI property worth $25,000,000. At a 70% max LTV the loan caps at $17,500,000. At a 10% debt yield it caps at $20,000,000. At a 1.25x DSCR it might support $21,000,000. The lender funds $17,500,000 — LTV binds here, but flip the appraisal down and debt yield takes over.

How to improve a thin debt yield

There are only two honest moves. Raise NOI — through higher rents, lower expenses, or burning off concessions — or reduce the loan you are asking for and bring more equity. No rate negotiation, amortization tweak, or appraisal will rescue a debt yield that is too low.

Because the metric is unforgiving, the smartest borrowers run it first. Before you submit anything, it is worth a moment to check whether your deal clears lender thresholds across debt yield, DSCR, and LTV together, so the binding constraint is something you chose to live with rather than a surprise on the term sheet.

Frequently asked questions

What is the definition of debt yield? Debt yield is the unlevered return a lender would receive if they foreclosed on a property today: net operating income (NOI) divided by the loan amount, expressed as a percentage. It is sometimes casually called NOI yield or loan yield, but debt yield is the standard underwriting term.

What is real estate debt? Real estate debt is the borrowed capital used to finance a property. A commercial real estate debt fund is a specific type of private lender that pools capital from investors to originate these loans, often using debt yield as their primary risk measure.

What debt yield do CMBS lenders typically require? Most CMBS programs set a hard floor between 8.5% and 10%. Office and unanchored retail regularly face requirements of 11%–13%. The percentage is set by securitization pool rules, not individual underwriter discretion.

Why doesn't a higher appraisal fix a weak debt yield? Debt yield only uses NOI and loan amount. Appraised value does not appear in the formula. A stronger appraisal improves LTV but leaves debt yield completely unchanged.

Can you negotiate a CMBS debt yield floor? The percentage floor is essentially fixed by securitization pool requirements. What you can negotiate is the NOI the lender uses.

What is the difference between As-Is and Stabilized debt yield? As-Is debt yield is calculated on the initial loan advance against current NOI. Stabilized debt yield is calculated on the full loan commitment against projected stabilized NOI. Both numbers appear on bridge and construction term sheets.

What is the fastest way to screen a deal for debt yield before submitting? Use the reverse formula: Max Loan = NOI ÷ Minimum Debt Yield. If your purchase price requires more debt than the result, you already know debt yield is the binding constraint. For step-by-step examples with real numbers, see how to calculate debt yield.

Does debt yield commercial real estate differ from residential? Yes. Debt yield real estate metrics apply exclusively to commercial income-producing properties. Residential lenders look at personal income (DTI), while commercial lenders look at asset income.

Debt yield is not complicated. It is one division. But it is the division that LTV and DSCR cannot stand in for — and the one most likely to decide how much a lender will actually give you.
