Debt Service Breakdown
DSCR = rental income ÷ debt service. Most lenders want 1.0 or higher; some allow below 1.0 with a larger down payment. No personal income docs required. Estimate only.
DSCR loans qualify investors on the property cash flow rather than personal income. The debt-service coverage ratio compares the monthly rent to the full mortgage payment, including taxes, insurance, and HOA.
A ratio of 1.0 means rent exactly covers the payment. Most lenders want 1.0 or higher, though some approve ratios slightly below with a larger down payment or reserves.
These figures are estimates. For neutral, official guidance on mortgage costs and what lenders can charge, see the CFPB's Owning a Home guide.

The Formula & Assumptions
PITIA = P&I + taxes + insurance
+ HOA
DSCR = monthly rent ÷ PITIA
Target: DSCR ≥ 1.00
The debt-service coverage ratio divides the property gross monthly rent by its full monthly obligation: principal, interest, taxes, insurance, and association dues.
A DSCR of 1.25 means the rent is 25% more than the payment, which lenders view favorably. A ratio under 1.0 means the property runs a shortfall and may require a larger down payment to qualify.
Because DSCR loans rely on the property rather than tax returns or W-2s, they are popular with self-employed investors and those scaling a portfolio. Rates run higher than owner-occupied loans.
Frequently Asked Questions
What DSCR do I need to qualify?
Most lenders look for a ratio of 1.0 or higher, meaning rent covers the full payment. Some programs allow ratios as low as 0.75 with a larger down payment, while a ratio of 1.25 or more earns the best pricing.
Do DSCR loans require income documentation?
No. DSCR loans qualify on the property cash flow rather than your personal income, so there are no tax returns, W-2s, or pay stubs required. That makes them ideal for self-employed investors.
What counts in the debt-service figure?
The full monthly obligation: principal, interest, property taxes, insurance, and any HOA or condo association dues. This is sometimes abbreviated PITIA.
Can I use projected rent instead of a current lease?
Often yes. Lenders typically accept a market rent analysis from the appraisal (Form 1007) when the property is not yet leased, using the lower of the lease or market rent.

It calculates the debt-service-coverage ratio on an investment property: rental income divided by the mortgage payment. DSCR lenders use that ratio to qualify the loan instead of your personal income.
DSCR Calculator in Florida
Florida's rental demand, driven by tourism, seasonal residents, and steady in-migration, supports strong DSCR numbers in many markets, from short-term rentals near the coast to long-term rentals in growing inland suburbs. Higher insurance premiums weigh on the debt-service side, so model them carefully when sizing the ratio.
How the DSCR 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.
The DSCR Formula, Explained
DSCR = monthly rental income / monthly debt service (PITI)
DSCR loans qualify the property, not the borrower's W-2 income, which makes them popular with investors and self-employed buyers. Lenders typically want a ratio of 1.0 or higher, and the best terms go to ratios around 1.25 and up.
The debt-service figure usually includes principal, interest, taxes, insurance, and any HOA dues. Higher rents or a lower payment both raise the ratio and improve loan terms.
The Complete DSCR Calculator 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.
DSCR Calculator FAQ
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.
