What Is a DSCR Loan? How Rent Qualifies a Rental in 2026

A DSCR loan is a rental-property loan that qualifies on the property's rent. The lender divides the monthly rent by the full monthly payment and asks whether the result clears its minimum. Your W-2s and tax returns stay out of the test, which is why the loan suits investors whose returns show depreciation and write-offs more clearly than they show income.

This guide walks through the ratio, one house financed at 3 different down payments, the 2 limits that decide how much a lender will lend, and the terms Sphinx Capital publishes for its DSCR program.

The ratio is the rent divided by the full monthly payment

DSCR stands for debt service coverage ratio. For a 1- to 4-unit rental it is usually calculated as:

DSCR = monthly rent / monthly PITIA

PITIA is the full payment: principal, interest, property taxes, insurance and any association dues. A ratio of 1.25 means the property brings in $1.25 for every $1.00 of payment. A ratio of 1.00 means the rent exactly covers it, and a ratio below 1.00 means the property needs outside money each month.

    D -->|Yes| E[Loan sized by<br/>LTV and coverage]
    D -->|No| F[Smaller loan or<br/>stronger rent]

Because taxes and insurance sit inside the payment, 2 identical houses can produce different ratios in different counties. A higher tax bill or a costlier insurance quote lowers the ratio as surely as a lower rent does.

Tax returns stay out because a rental loan is a business loan

Federal lending rules require a lender making a consumer mortgage to verify the borrower's ability to repay from income. Business-purpose credit is exempt, and the Consumer Financial Protection Bureau's official interpretation of Regulation Z states that credit "to acquire, improve, or maintain rental property (regardless of the number of housing units) that is not owner-occupied is deemed to be for business purposes." A DSCR loan sits on that side of the line, so the property's income can carry the file.

The rest of the file still matters. Lenders review credit, cash reserves, the entity that will own the property and the appraisal. Many DSCR loans close in the name of an LLC that owns the rental.

One $300K house at 3 down payments shows how leverage moves the ratio

Here is a single-family rental bought for $300K that rents for $2,300 a month, with $250 a month in property taxes and $150 in insurance. The rate is an illustrative 7.00% on a 30-year schedule, held the same at every down payment to isolate the effect of the loan size:

Every additional $15K of loan costs about $100 a month and takes 0.06 to 0.07 off the ratio. The same house clears 1.00 at all 3 down payments and clears 1.20 only at 75% LTV or less. The DSCR calculator runs this arithmetic on your own rent, taxes and insurance, and the DSCR calculation guide covers how lenders treat vacancies, short-term income and interest-only payments.

The loan is the lower of 2 limits: leverage and coverage

A DSCR lender sizes the loan twice and lends the smaller result:

• The leverage limit. The loan divided by the purchase price or appraised value. At 80% LTV, the $300K house supports $240K.
• The coverage limit. The largest loan whose payment the rent still covers at the required ratio. At 1.00, $2,300 of rent supports a payment of $2,300, and after $400 of taxes and insurance that leaves $1,900 for principal and interest, about $286K of loan at 7.00%. At 1.20, the rent supports a $1,917 payment and about $228K of loan.

In this example, leverage binds at a 1.00 minimum and coverage binds at 1.20. When coverage is the limit, the remedy is a larger down payment, a lower rate or a property whose rent is stronger relative to its price. The down payment guide works through that trade in more detail.

Rent comes from the lease or the appraiser's rent schedule

The rent in the ratio has to be documented. On a refinance of a leased property, it starts with the current leases and rent roll. On a purchase, the appraisal commonly includes a rent schedule, such as Fannie Mae's Single-Family Comparable Rent Schedule (Form 1007) for a house, which estimates market rent from comparable rentals nearby. Lenders often use the lower of the lease and the market estimate.

Short-term rentals are a separate case: a lender counts booking history or market data for comparable short-term rentals, as the short-term rental DSCR guide explains.

Sphinx Capital's published DSCR terms

Sphinx Capital's DSCR program publishes these terms:

"From 6.25%" is the start of the range. The program pages note that rates and other terms "may vary based on the creditworthiness of the borrower, property type and state, and other considerations," so the rate on a given file depends on its leverage, coverage and credit. The DSCR rate guide explains what moves pricing, and the requirements guide covers what a lender checks before it says yes.

The same terms apply to refinancing, rate-and-term or cash-out, and to long-term rental properties bought to hold. Buildings of 5 to 20 units fall under the multifamily program, which publishes its own rate from 7.25%. Stabilized mixed-use and other commercial property is financed under Commercial Permanent.

State rules move the tax and insurance lines

The ratio is national; its inputs are local. Property tax law, insurance markets and eviction timelines differ by state, and each one reaches the payment or the rent. The state guides cover the rules that matter for a DSCR file in Texas, Florida and Missouri, and the DSCR loans by city page lists every state and city guide as it is published.

What to send for the fastest decision

DSCR underwriting is lighter than bank underwriting, and the lender still needs proof that the property performs:

Sending everything at once keeps the file moving. A missing document usually costs more time than any single step in underwriting.

Plan for the costs that change a DSCR deal after the offer

The most common surprise is a ratio that falls once the real tax bill and insurance quote replace estimates. Build the payment from documents, then size the loan.

When a DSCR loan fits, and when a bridge loan comes first

A DSCR loan fits when:

• The property is leased, or has documented short-term rental history.
• You have a current rent roll, tax bill and insurance quote.
• You know your target loan amount and how long you plan to hold.
• You are refinancing out of a bridge or hard-money loan on a stabilized property.

A bridge loan comes first when:

• The property is under renovation or still being leased up.
• The rent does not yet support the payment you need.
• You need to close faster than a long-term loan can be underwritten.

The bridge loan guide covers the short-term side of that plan, and the bridge-to-DSCR refinance timeline shows how the 2 loans connect once the property is leased. The DSCR refinance guide compares rate-and-term and cash-out refinances for properties you already own. When the rent, taxes and insurance are documented and the ratio clears with room to spare, the file is ready to submit.
