What DSCR Ratio Do You Need? (And How to Improve It)

Most DSCR lenders want a ratio of 1.0 or higher, meaning the property's rent covers its full mortgage payment. Some programs allow ratios below 1.0 with a larger down payment or reserves, and the higher your ratio, the better your rate and terms.

How the ratio is calculated

DSCR is the property's monthly rental income divided by its total monthly payment (principal, interest, taxes, insurance, HOA). If a property rents for $2,500 and the full payment is $2,000, the DSCR is 1.25, the rent covers the payment with 25% to spare. If it rents for $1,800 against a $2,000 payment, the DSCR is 0.90, and the rent falls short. You can run these numbers on your own scenario to see where a property lands.

What the numbers mean

A DSCR of 1.0 is break-even, rent exactly equals the payment. Most lenders treat 1.0 as the baseline for standard approval. Ratios of 1.25 and above are strong and typically earn the best pricing. Ratios below 1.0 (the property doesn't fully cover itself) aren't automatically disqualifying, but they require a program that allows it, usually with a larger down payment, stronger credit, or more reserves to offset the gap.

The short-term rental lever

This is where the ratio can transform. A property analyzed at its long-term lease rate might come in at 0.95, just under the line. Analyzed as a short-term rental using AirDNA-supported projected income, that same property might show 1.4, comfortably approvable with better terms. For properties in strong short-term rental markets, using AirDNA data instead of the long-term rent figure is often the single biggest factor in both qualifying and getting a better rate.

How to improve your DSCR

Beyond the short-term rental angle, you can raise your ratio by putting more money down (which lowers the payment and improves the ratio), buying in a market with stronger rent-to-price ratios, or choosing a property that rents well relative to its cost. A larger down payment does double duty: it lowers the payment and often unlocks a better rate tier. The practical goal is simple — structure the deal so the property clears the minimum ratio the program requires.

Why it matters beyond approval

The DSCR ratio doesn't just decide yes or no, it drives your pricing. A property at 1.5 gets better terms than one at 1.0. So it's worth structuring the deal, through down payment and income analysis, to land your ratio as high as practical, not just above the minimum.
