Debt Yield Explained: The Lending Metric That Really Sets Your Loan Size

What it is

Debt yield is simple math: net operating income divided by the loan amount. That's it. No amortization schedule, no interest rate, no term assumptions. If a deal produces $500,000 in NOI and the loan is $6,250,000, the debt yield is 8%.

Lenders like it because it strips away the variables that made debt service coverage ratio (DSCR) less reliable when rates started moving around. DSCR tells a lender how comfortably the property covers its payment. Debt yield tells them something blunter: if they had to foreclose tomorrow and sell the asset at a cap rate equal to that yield, would they get their principal back. It's a floor, not a forecast.

How it plays out in retail net lease

Here's the mistake I see constantly. A buyer runs their numbers off DSCR, sees a comfortable 1.35x coverage at a given rate, and assumes that sets the loan amount. Then the term sheet comes back smaller than expected, and nobody can figure out why.

What happened is the lender ran debt yield as a secondary test and it came in tighter than DSCR did. On single-tenant net lease deals — where cap rates and loan rates can sit close together — that's common. A credit tenant on a long lease with modest rent bumps can produce a DSCR that looks fine, but if the in-place NOI is thin relative to the loan request, debt yield pulls the leverage down regardless of what the coverage ratio says.

This shows up most on lower cap rate deals with investment-grade tenants — the properties that feel like the "safest" buys. The safety is real, but a low cap rate usually means a low NOI relative to price, and that's exactly the ratio debt yield is testing. I've had clients assume a strong tenant automatically means max leverage. It doesn't. The tenant's credit affects the risk lenders will accept; the debt yield affects how much they'll lend against it.

What to watch for

• Ask your lender for the minimum debt yield they're underwriting to before you go under contract, not after you've locked a rate — it varies by lender, property type, and tenant credit.
• Don't assume a strong DSCR protects your loan amount. Get both numbers from your lender in writing.
• Low cap rate deals (sub-6%, common with investment-grade single-tenant retail) are the ones most likely to get capped by debt yield rather than DSCR.
• Rent bumps and lease term matter here too — a flat, long-term lease with no escalations keeps NOI static while your loan request may not be.
• If you're refinancing, run debt yield on current NOI, not projected. Lenders generally do the same.

How to use it to your advantage

Know your number before you shop the loan. Calculate debt yield yourself at a few loan sizes before you talk to a lender, so when the term sheet comes back you know whether it's rate-driven or debt-yield-driven. That changes how you negotiate.

If debt yield is the binding constraint, a lower interest rate won't fix your leverage problem — a bigger down payment, a higher-NOI property, or a different lender's threshold will. I've steered clients toward regional and community banks on deals where the debt yield floor from a CMBS or life-co lender was killing the proceeds they needed. Different lenders set different floors, and shopping that number can be worth more than shopping rate.

Best case, worst case

Best case:

• Your NOI comfortably clears the lender's debt yield floor, so the loan amount is set by DSCR or LTV instead — you get full leverage
• Strong debt yield gives you room to negotiate rate or structure, since the lender's downside is already well covered
• A high debt yield deal tends to be easier to refinance later, even if rates move

Worst case:

• Debt yield caps your loan below what DSCR and LTV would otherwise allow, and you're short on proceeds at closing
• You lock a rate before knowing your debt yield number, then get a smaller term sheet than expected and lose time re-trading the deal
• On a refinance, NOI hasn't grown enough to clear the current debt yield threshold, forcing a paydown you didn't plan for
