It calculates the debt-service-coverage ratio on an investment property — rental income divided by the mortgage payment — which DSCR lenders use to qualify the loan instead of your personal income.
The Complete Guide
DSCR loans changed real estate investing by removing personal income from the equation. Instead of tax returns and pay stubs, the lender looks at whether the property's rent covers its mortgage — a far simpler path for investors with complex finances.
The ratio is everything. At 1.0 the rent just covers the payment; most lenders want a cushion, and stronger ratios unlock better rates and higher leverage. Raising rent or increasing the down payment are the two levers that move it.
In Florida's rental markets, DSCR financing is a workhorse for both long-term and short-term rental investors. Use the calculator to test how rent assumptions and the insurance line affect your ratio before you commit to a property.
How the Calculator Works
The calculator divides the property's monthly rental income by its monthly debt obligation. A ratio of 1.0 means rent exactly covers the payment; above 1.0 means positive coverage, which lenders prefer.
Frequently Asked Questions
What DSCR do lenders want?
Most look for a ratio of at least 1.0, meaning rent covers the payment, with the best terms at roughly 1.25 or higher. Some lenders allow ratios slightly below 1.0 with compensating factors.
Does my personal income matter for a DSCR loan?
Generally no. DSCR loans qualify on the property's cash flow rather than your W-2 income, which is why investors and self-employed buyers favor them.
