DSCR Calculator (Rental and STR Mortgage)

DSCR loans qualify on the property's income instead of your pay stubs. Lenders compare monthly rent with the full payment: principal, interest, taxes, insurance and HOA (PITIA).

Results

How it works

Loan = price x (1 - down payment). PITIA = principal and interest + tax / 12 + insurance / 12 + HOA. DSCR = monthly rental income / PITIA. Rent needed for a target DSCR = PITIA x target.

FAQ

What DSCR do lenders want?

Many look for 1.0 or higher, and better pricing often starts around 1.2 to 1.25. Each lender sets its own rules.

How is STR income counted?

Lenders often use a 12-month booking history or a third-party revenue estimate, sometimes with a haircut. Ask yours which one.

Is this the same as NOI-based DSCR?

Commercial loans divide net operating income by debt service. Residential DSCR loans usually use gross rent over PITIA, which is what this shows.
