Low DSCR Review

When the DSCR is too low, start with the math—not the decline.

A low ratio can come from limited rent, an overstated payment, taxes and insurance, the requested leverage, or the lender’s qualifying rules.

The Core Formula

DSCR compares qualifying rent with the qualifying property obligation.

General illustration

DSCR = qualifying monthly rental income ÷ qualifying monthly housing obligation. The obligation commonly includes principal and interest or the qualifying interest-only payment, property taxes, insurance, HOA dues, and flood insurance when applicable. Each lender’s rules control the final calculation.

Why the ratio may be lower than expected

1

The usable rent was reduced

The lender may use market rent instead of the lease, limit excess lease rent, apply a short-term rental expense factor, or reject unsupported income.

2

The qualifying payment is higher

A different rate, fully amortizing payment, property taxes, insurance, HOA, or flood premium may have been added to the calculation.

3

The requested loan amount is too high

Reducing leverage or cash out can lower the payment and may move the scenario into a workable DSCR tier.

4

The program has a minimum-ratio overlay

Some programs price or restrict ratios below 1.00, while others may permit lower ratios with stronger credit, lower LTV, or additional reserves.

Potential Adjustments

What may improve a low-DSCR transaction.

01

Support more rent

Provide an eligible lease, market-rent form, short-term rental history, or current proof of receipt when the program permits it.

02

Lower the payment

Test available leverage, term, rate, points, or interest-only structures without assuming a program is available.

03

Reduce the request

Lower the loan amount, cash out, or payoff requirement to improve both DSCR and LTV.

04

Use a lower-DSCR program

When available, a program may allow a ratio below the first lender’s minimum with compensating factors.
