A debt service coverage ratio (DSCR) loan is an investment-property mortgage that qualifies you based on the property’s cash flow rather than your personal income. The key number is the DSCR itself.
The formula (done right)
DSCR = Net Operating Income ÷ Annual Debt Service
In plain English: the property’s annual rental income minus operating expenses, divided by the annual mortgage payments. A DSCR of 1.0 means the income exactly covers the payments. Above 1.0 means there’s a cushion; below 1.0 means the property doesn’t cover its own debt.
Lenders generally want to see a DSCR comfortably at or above 1.0 — many prefer a cushion above that — and stronger ratios earn better rates and terms.
Why investors use DSCR loans
- Qualify on the property, not your paycheck. Self-employed borrowers and portfolio investors who don’t fit traditional income documentation often use DSCR loans.
- Scale faster. Each property is evaluated on its own cash flow, which simplifies building a rental portfolio.
- Less personal paperwork than conventional underwriting in many programs.
What lenders still check
A DSCR loan isn’t free money. Lenders typically evaluate your credit score, the loan-to-value ratio, cash reserves, the property type and condition, and the local rental market. Expect larger down payments and higher rates than owner-occupied financing.
The bottom line
If you’re buying Florida rental property and the numbers work — real rents, real expenses, DSCR with a cushion — a DSCR loan can be a clean, businesslike way to finance it. Run the cash flow conservatively first: the ratio only protects you if the income figure is honest.
