What is debt yield, and why did my lender mention it?
Debt yield is your property's net operating income divided by the loan amount, written as a percentage. It answers one question — if the lender foreclosed tomorrow, what cash return would the property give them on the money they lent? Unlike coverage and loan to value, it ignores the interest rate, the amortisation and the appraisal, so it cannot be flattered by cheap debt or a generous valuation.
The calculation
Debt yield = Net operating income ÷ Loan amount
That is the whole formula. A worked example:
| Item | Amount |
|---|---|
| Net operating income | 300,000 |
| Loan amount | 3,000,000 |
| Debt yield | 10.0% |
Turn it around and it sizes a loan directly. If a lender's floor is 10 percent and your net operating income is 300,000, the largest loan that clears the test is 3,000,000. Divide the income by the floor.
Why lenders trust it
The other two tests both depend on something outside the property.
Debt service coverage depends on the loan terms. Take a property with 300,000 of net operating income. At 7 percent over a 25 year amortisation, a 3,000,000 loan produces coverage near 1.18. Drop the rate to 5.5 percent and the same loan on the same property produces coverage near 1.36. Nothing about the building changed. The lender's cushion appears to have grown because debt got cheaper.
Loan to value depends on the appraisal. Value is an opinion supported by comparable sales, and comparable sales lag the market. In a rising market an appraisal validates a price that a forced sale would not recover.
Debt yield depends on neither. Income divided by loan. If the lender took the property back and ran it, that percentage is the unlevered cash return on their exposure. It is deliberately pessimistic, and that is the point.
Where it comes from
Debt yield became a standard test after the 2008 financial crisis, when loans underwritten on coverage and loan to value alone proved to have been sized against cheap debt and optimistic appraisals. A measure that ignored both was the correction.
What moves your number
Only two things, because only two things are in the formula:
- Raise net operating income. Raise rents to market, cut a controllable expense, reduce vacancy, or add an income line. This is the lever that also raises the property's value, so it is worth more than it looks.
- Reduce the loan. More equity, or a smaller purchase price.
Note what is not on that list. Shopping for a lower rate does not change your debt yield. Asking for a longer amortisation does not change it. Those help coverage; they do nothing here.
How it interacts with the other two tests
A lender applies all three and lends the smallest result. So the binding constraint moves with conditions:
- When rates are low, coverage is easy to clear and debt yield usually binds.
- When rates are high, coverage tightens and often binds first.
- When values run ahead of income, debt yield binds, because the appraisal cannot help it.
Our loan sizing tool runs all three against your figures and names the one that limits you. Knowing which test binds tells you what to fix.
What to ask your lender
Three questions, and the answers are more useful than a rate:
- What is your current debt yield floor for this property type?
- When did it last change, and in which direction?
- Which of the three tests is binding on my deal?
A lender who answers the third question clearly is telling you exactly what to work on.
Common questions
How do I calculate debt yield?
Divide the annual net operating income by the loan amount, then read it as a percentage. A property with 300,000 dollars of net operating income and a 3,000,000 dollar loan has a debt yield of 10 percent. Nothing else enters the calculation — not the rate, not the amortisation, not the value.
What debt yield do lenders require?
It varies by lender type, property type and market, and it moves with conditions. As a rule the figure is set as a floor rather than a target, and a lender applies it alongside coverage and loan to value, taking whichever of the three produces the smallest loan. Ask any lender quoting you for their current floor by name, and ask when it last changed.
Why do lenders use debt yield instead of just coverage and loan to value?
Because both of those can be flattered. Debt service coverage improves if the rate falls or the amortisation lengthens, even though the property has not changed. Loan to value depends on an appraisal, and appraisals rise in a hot market. Debt yield uses only the income and the loan, so it measures the property rather than the financing or the valuation.
Is a higher or lower debt yield better for me as a borrower?
A lower required debt yield lets you borrow more against the same income, so a borrower prefers a lender with a lower floor. Your own property's debt yield rises when income rises or when the loan shrinks. If a lender's floor is blocking your loan size, the fixes are to raise net operating income or to put in more equity.
Does debt yield apply to every commercial loan?
It is most associated with CMBS and with debt funds, and it is common at banks and life companies too. Not every lender states it as a formal test, but most look at the income-to-loan relationship in some form. If a lender has never mentioned it to you, ask — it is often the limit that binds without being named.
