What is a DSCR loan?
A DSCR loan is an investment-property mortgage that qualifies on the property's rental income — not your tax returns, W-2s or paystubs. The debt service coverage ratio divides qualifying monthly rent by qualifying monthly housing expense: principal, interest, taxes, insurance and association dues. A ratio of 1.0 means the rent covers the payment; above 1.0 means cash flow to spare.
Texas is one of the strongest DSCR states in the country because rents remain competitive relative to purchase prices across most metros. But Texas also carries some of the highest property taxes in the nation — and taxes sit in the denominator of the ratio. Two houses at the same price can carry very different qualifying expenses once a MUD district, a coastal windstorm policy or a flood zone designation enters the picture.
Illustration — same price, different ratio
- Qualifying monthly rent
- $2,400
- Expense at a 1.7% tax rate
- $2,120 → DSCR ≈ 1.13
- Expense at a 2.6% MUD-area rate
- $2,420 → DSCR ≈ 0.99
Illustration only. Qualification, calculation methods, documentation, property eligibility, reserves, rates and terms vary by lender and program. This is not a pre-qualification, approval or commitment to lend.
That gap is the entire reason to price taxes and insurance before you write the offer. It is also why structure matters: down payment, term, and interest-only availability all move the denominator.
Who DSCR financing tends to fit
- Investors buying long-term single family or 2–4 unit rentals
- Portfolio investors adding doors beyond typical agency financed-property limits
- Borrowers who own through an LLC or other entity
- Short-term rental operators, where the program and market allow
- Self-employed investors whose tax returns understate real cash flow
- Owners pursuing cash-out on an existing investment property
