DSCR measures cash flow; LTV measures leverage. DSCR is the cushion between what the deal earns and what it owes each year. LTV is how much of the asset's value you're financing. Lenders use both as separate gates — passing one doesn't save you from failing the other.
When a lender sizes a loan, they're managing two different risks. The first: can the deal actually make its payments? The second: if it can't, and they have to take the asset back, will it be worth enough to cover the loan? DSCR answers the first question. LTV answers the second. Understanding the split is what stops a deal from dying at underwriting for a reason you didn't see coming.
What DSCR measures
Debt service coverage ratio compares the income a deal produces to the debt it has to service each year. A DSCR of 1.25x means the income is 25% more than the annual loan payments — a cushion before the deal can't cover its debt.
It's a cash-flow test. It protects the lender against the most common failure: a borrower who simply can't make the payments.
What LTV measures
Loan-to-value compares the loan amount to the value (or purchase price) of the asset. An 75% LTV means you're borrowing 75% and bringing 25% as a down payment.
It's a leverage and collateral test. It protects the lender against loss if they have to foreclose and sell — the more equity you put in, the more the asset can drop in value before the lender is underwater.
DSCR vs. LTV, side by side
| DSCR | LTV | |
|---|---|---|
| Question it answers | Can the income cover the debt? | How much is borrowed against the asset? |
| Formula | NOI ÷ Annual Debt Service | Loan Amount ÷ Property Value |
| Measures | Cash flow / affordability | Leverage / collateral |
| Lenders typically want | 1.20x – 1.25x+ | 65% – 80% or lower |
| Protects against | Default — can't make payments | Loss on foreclosure / resale |
| Improve it by | Lower loan, longer amortization, higher NOI | Larger down payment, lower price or loan |
Why lenders use both
Because a deal can look fine on one and fail on the other — and each failure is its own kind of trouble.
Picture a property bought with a big down payment: low LTV, looks safe on leverage. But if the rents barely cover the mortgage, the DSCR comes in at 1.05x and the lender balks — there's no cushion, and a single vacancy tips it into the red. Equity didn't fix a cash-flow problem.
Now the reverse: a property with strong cash flow and a 1.45x DSCR, but financed at 90% LTV. The payments are covered, but the lender is barely protected if values dip and they have to sell. Great cash flow didn't fix a leverage problem.
That's why both gates exist. On income-producing deals, lenders size the loan to the lower of what DSCR supports and what LTV allows — whichever is more conservative wins.

What is the difference between DSCR and LTV?
DSCR measures whether the income covers the loan payments — affordability and cash flow. LTV measures how much you're borrowing against the asset's value — leverage and collateral. One asks "can the deal pay the debt?"; the other asks "how much is at risk against the asset?"
Which matters more, DSCR or LTV?
Neither alone — lenders treat them as two separate gates, and a deal has to clear both. For income-producing property, DSCR often sets the maximum loan the cash flow supports, while LTV caps it from the collateral side. Whichever produces the smaller loan governs.
What is a good LTV?
Lower is safer. Many commercial and multifamily lenders cap LTV around 65–80%, meaning a 20–35% down payment. A lower LTV (more equity) reduces the lender's risk and usually earns better terms.
Can you have good LTV but bad DSCR?
Yes. A large down payment gives a low, attractive LTV, but if income barely covers the payments, DSCR can still fall below the minimum — and the lender will decline or resize the loan even though the LTV looks fine.
