FAQ: What Debt Yield Floor Works in Tertiary Markets?
Debt yield is the one lender test that ignores both the interest rate and the appraisal. Why tertiary-market floors sit higher, and what to underwrite to.
Debt yield is the least discussed and most decisive of the three loan-sizing tests. Understanding why lenders lean on it explains most of what happens to proceeds in a small market.
What debt yield is
Debt yield = net operating income ÷ loan amount.
A $900,000 NOI against a $10,000,000 loan is a 9% debt yield. That is the whole formula.
What makes it powerful is what it leaves out. Debt yield contains no interest rate and no appraised value. It answers one question: if the lender took the keys tomorrow, what unlevered return would the property produce on the money lent?
Loan-to-value depends on an appraisal, which is an opinion. DSCR depends on the coupon, which changes. Debt yield depends on the property's income and the loan balance, both of which are facts. That is why it became the binding constraint for most lenders after 2008 and why it does more work than the other two tests in markets where appraisals are unreliable.
Why tertiary floors are higher
Lenders set higher debt yield floors in smaller markets for reasons that are, on the whole, defensible:
Exit uncertainty. The floor is the lender's protection against having to sell the asset. In a market with few buyers, that sale takes longer and clears lower, so the cushion has to be larger.
Appraisal dispersion. With few comparable trades, the range of defensible values widens. A lender that cannot trust the value leans harder on the test that does not use it.
Income volatility. A 200-unit property in a metro with one dominant employer has a different NOI risk profile from the same property in a diversified metro, even at identical current occupancy.
Lender concentration. Fewer lenders means less competitive pressure to loosen terms.
What floors actually look like
Debt yield floors are set lender by lender and move with the credit cycle, so treat any single number as a starting point for a conversation rather than a rule. The pattern that holds across environments is the spread between market tiers, not the absolute level.
As a working frame for underwriting:
| Setting | Typical posture |
|---|---|
| Primary market, stabilised multifamily, agency execution | The most generous floors available |
| Secondary market, stabilised multifamily | Modestly higher |
| Tertiary market, stabilised multifamily | Higher again, often by 100–200 bps over primary |
| Tertiary market, non-multifamily | Highest, and most variable by lender and asset |
| Transitional or lease-up assets, any market | Sized on stabilised NOI with a holdback, or not sized on debt yield at all |
The practical implication: underwrite to a floor above what you have been quoted. If a lender indicates 9%, model your maturity refinance at 10%. The floor that matters is not today's — it is the one in force when you refinance, set by a lender you have not met, in a credit environment you cannot forecast.
How the floor caps your proceeds
Rearranged: maximum loan = NOI ÷ debt yield floor.
At $900,000 of NOI:
- 8% floor → $11.25m
- 9% floor → $10.0m
- 10% floor → $9.0m
- 11% floor → $8.18m
A 200 basis point move in the floor removes roughly a quarter of your proceeds, with no change in the property, the rate, or the appraisal. If your refinance plan needed $10m and the floor moves to 11%, you have an $1.8m gap to fund — see how to underwrite refinance risk in non-core markets.
What this means for how you underwrite
Use in-place NOI, not stabilised. Lenders will trend toward what the property actually produces, especially in markets where they doubt the lease-up assumption. Test your refinance on today's income as well as your projection.
Normalise the expense line honestly. Debt yield is only as good as the NOI beneath it. A seller's operating statement missing management fees, understating insurance, or capitalising what should be repairs will produce a debt yield that no lender will agree with. Insurance in particular has repriced enough to move NOI materially in several states.
Remember it is asymmetric. Rising rates hurt DSCR and leave debt yield untouched. Falling NOI hurts all three tests at once. That is the scenario to reserve against.
Check which test binds. Run all three at several rate and cap-rate combinations, and note which one produces the smallest loan. In tertiary markets it is usually debt yield, which means arguing about the appraisal is wasted effort.
Rules of thumb worth carrying
- Underwrite your exit refinance at a floor 100–200 bps above your acquisition quote.
- If the deal only works at the most generous floor you have ever been quoted, it does not work.
- A deal that clears the floor on in-place income has genuine resilience. One that clears only on stabilised income is a bet on execution.
- Amortisation improves your future debt yield by reducing the loan balance. In thin markets that is worth the cash flow it costs.
What to do next
- Model coverage alongside it with DSCR sensitivity design for smaller lending pools.
- Run the combined test in cap rate, debt yield and exit cap stress test.
- Check the term sheet's stated floors with the debt term sheet checklist for non-core acquisitions.
- Compute coverage with the DSCR calculator.
