A DSCR loan is a business-purpose mortgage on an investment property that is qualified on the property's rent rather than on your personal income. The lender compares the rent it will accept against the monthly housing payment, and that ratio — the debt service coverage ratio — drives whether the file works and on what terms. The qualifying analysis sits on the property, so the personal-income documentation a conventional file turns on is not what carries this one. The lender still underwrites you: credit, assets, reserves and the entity you close in.
This guide explains what these loans are, how the decision actually gets made, and what to settle before you commit to a property or a structure.
What a DSCR loan is, and who it is for
DSCR loans are for non-owner-occupied residential investment property — single family, condo, townhouse and 2-4 unit buildings are the usual range, with separate products for larger buildings. These are business-purpose loans. Credit extended primarily for a business or commercial purpose is generally exempt from Regulation Z, and the facts of the transaction determine how it is classified, which is one reason lenders ask how you will use the property.
The structure tends to suit an investor whose tax returns understate their buying power: self-employed income, heavy depreciation, several properties already financed, or a recent job change that a conventional file would struggle with. It suits a property that carries itself. It suits a borrower who wants to add properties without each one re-testing their personal income.
It is a worse fit when the property's rent is thin relative to the payment, or when you are buying something the rental products treat as unusual. On cost, do not assume a direction: compare the actual fees, the payment and the exit terms you are quoted against your alternatives.
If you plan to close in an LLC, confirm that the lender accepts that vesting and which entity documents it requires.
How the ratio works
The method explained here divides rent by the monthly housing payment, PITIA — principal and interest, taxes, insurance and any association dues:
DSCR = gross monthly rent ÷ monthly PITIA
Products vary the inputs. An interest-only payment produces a different denominator, and some products qualify on a different measure entirely, so confirm which one applies to your file.
A quick example. Rent of $2,000 against a payment of $1,549.59 — $1,199.59 of principal and interest, $250 of taxes, $100 of insurance, no dues:
$2,000 ÷ $1,549.59 = 1.29
Add $150 of monthly association dues and the payment becomes $1,699.59, so the ratio falls to 1.18. The dues belong in the denominator; subtracting them from rent instead answers a different question and produces a different number — about 1.19 on these figures.

That is the arithmetic. The rest of this page is what moves it and what sits around it.
Which rent counts
Two investors can run the same formula on the same property and get different ratios, because the lender decides which rent figure qualifies. Confirm whether the lender will use market rent, lease rent, or another documented figure for your purchase or refinance, and what evidence it needs.
The appraisal is where a market-rent figure comes from: the Single-Family Comparable Rent Schedule, Fannie Mae Form 1007, for a single unit, and Form 1025 for a small residential income property of two to four units. These forms document appraisal information; they do not themselves set which figure a lender accepts.
Three situations are worth raising before you go under contract:
- The property is vacant. This does not automatically rule out a DSCR loan. Ask whether the lender can qualify on market rent, whether a signed lease is required before closing, and whether vacancy changes the leverage available to you.
- Your lease is above market rent. Ask what proof the lender wants — how many months of rent received, and whether prepaid rent counts.
- It is a short-term rental. Confirm how the lender will assess the short-term income and which supporting evidence it needs. More on that below.
Because the rent figure has to be supported before anyone can rely on it, settle which source governs early. Your final loan amount follows the rent the lender accepts, not the rent you projected.
What sets your terms besides the ratio
Clearing a minimum ratio is not the same as getting the terms you assumed. The ratio is one input among several that together set your leverage.
Leverage depends on the combination of the coverage ratio, your credit score, the loan size and the purpose. The lender evaluates those factors together when setting the maximum loan amount. A product's headline LTV does not tell you what applies to your particular file. Ask for the maximum leverage at your actual ratio, score, loan amount and purpose.
Minimum ratios differ by product, and below-1.00 options exist. Some rental products are built around a 1.00 floor. Others accept a ratio below 1.00 in exchange for tighter terms, and some lenders run a separate no-ratio product for files below their lowest DSCR band. A no-ratio product is a different analysis, not a lower bar on the same one, so ask what it qualifies on and what conditions come with it.
Reserves scale with the loan. Requirements range from none at all on smaller loans to several months of PITIA as the loan amount rises, and larger loans can require substantially more. Some products allow cash-out proceeds to satisfy the requirement, which changes how much of your own liquidity you need at closing. Get the number for your loan size before you plan your cash.
Short-term rentals need a separate income review. Before relying on projected income, confirm that the DSCR lender accepts short-term rentals for your purchase or refinance and location. Settle the qualifying income method, the minimum ratio and maximum leverage together. A projection from a data provider and twelve months of actual receipts are different evidence; find out which the lender will use.
First-time investors face additional conditions. If this is your first rental, ask whether the product applies a higher minimum ratio, a higher credit-score floor, lower leverage, a loan-size cap or additional reserves. Being a first-time investor and a first-time homebuyer are separate eligibility questions. A product can accept your first rental purchase while excluding first-time homebuyers, so confirm both.
Where the property sits can decide the file. A lender's product can exclude particular locations or property types, including rural properties. Those exclusions are lender-specific, so a property one lender cannot finance may be ordinary for another. Confirm the location is eligible before an appraisal is paid for.
Prepayment terms depend on the product, the state and how you vest. A prepayment penalty may apply, and whether one is available at all can turn on the state and on whether you close as an individual or in an entity. These are product and licensing terms rather than a single national rule, so ask what applies to your transaction and price your exit accordingly.
Detailed eligibility — documentation, credit events, property condition, seasoning — is covered in DSCR loan requirements.
Purchase and refinance run differently
On a purchase, the sequence is: confirm the property type and location are eligible, estimate the payment, establish which rent figure the lender will use, and check the resulting ratio against the product. The appraisal carries the market-rent schedule, so agree early with your loan officer when that figure will be available relative to your inspection period.
On a refinance, an existing lease is part of what the lender reviews, and two extra questions appear. Compare the maximum leverage, rate and fees for rate-and-term and cash-out on your actual file. Do not assume the same terms apply to both. Lenders also set their own seasoning expectations for how long you must have owned the property, which matters if you bought recently or just finished a renovation.
What the ratio does not tell you
A ratio above 1.00 means the qualifying rent exceeds the qualifying payment under the gross-rent and PITIA method used here. It does not mean the property makes money. PITIA leaves out vacancy, repairs, management, utilities you cover and capital items like roofs and water heaters. A property can clear the coverage test and still cost you money every month.
It is also not an approval. A loan officer organizes and presents the file; underwriting applies the lender's credit policy and makes the decision. Identifying a likely problem and restructuring a submission is not the same as issuing an approval, and no ratio on its own makes a file eligible.

Questions worth asking before you choose
When you compare two offers, compare whole packages rather than headline numbers:
- Which rent figure will you use for my transaction, and what documentation do you need?
- Which product is my file going into, and what is its minimum ratio?
- At my ratio, credit score, loan amount and purpose, what is the maximum leverage?
- What reserves apply at this loan size, and can cash-out proceeds count toward them?
- What are the prepayment terms for my state and my vesting, and what would an early exit cost?
- If the appraisal supports a lower market rent than I expect, what happens to my loan amount?
