Start with market rent
The lender looks at the monthly rent the property can reasonably produce, supported by the appraisal and available rent evidence.

The investor loan guide
Financing for an investment property that's decided by the property's rental income versus its mortgage payment, not by the borrower's personal income.

Pre-qualification is a preliminary inquiry only — it is not an approval, pre-approval, rate quote or commitment to lend.

The short version
DSCR stands for debt-service coverage ratio. It is a way to compare the income a property is expected to produce with the monthly debt payment it would carry. A higher ratio generally means more room between rent and the payment.
Because the property’s income is central, W-2s, pay stubs, and personal tax returns typically are not the deciding factor in the same way they are with conventional financing. The borrower, property, leverage, credit, reserves, and program guidelines still come into view.
This approach is built for real estate investors, from someone buying a first rental to an operator financing a multifamily building. DSCR Doctors works across both residential and commercial investment property.
The core calculation
The math is simple. The right loan structure depends on the full property and borrower story around it.
The lender looks at the monthly rent the property can reasonably produce, supported by the appraisal and available rent evidence.
Next comes the monthly debt payment the proposed loan would create, along with other property costs that may be part of the review.
DSCR is rent ÷ payment. Many lenders use roughly 1.20 and up as a rule of thumb, though programs vary by deal.
That ratio works alongside the appraisal and LTV to shape the loan amount, equity, and terms available for the property.

The full review
Property income starts the conversation, but a responsible loan review connects the income to the value, condition, leverage, and borrower behind the deal.
The property’s market rent and the ratio it produces help show whether income covers the debt.
An appraisal supports value, rent, and condition. Repairs or deferred maintenance can affect the review.
Loan-to-value connects the loan amount to the property value, so leverage and cash invested move together.
Credit history and score are still part of the borrower review, even when personal income is not the main test.
Lenders may want funds set aside for payments, closing, and the normal surprises of owning a rental.
When an LLC holds the property, expect formation, ownership, authorization, and guarantor information to be reviewed.
Why investors choose the model
Qualification can center on the asset instead of W-2s, pay stubs, and tax returns.
An entity can fit the way you organize ownership, subject to lender and guarantor requirements.
Property-income-based programs may fit rentals or borrower profiles conventional loans do not.
Keep building a portfolio without relying only on conventional personal-income calculations.
Begin with the deal and the property numbers rather than a large personal-income file.
Well-performing properties can support the conversation, while leverage, credit, and reserves still shape terms.

Questions, answered
A DSCR loan is financing for an investment property that looks at the property’s rental income against its debt payment. DSCR stands for debt-service coverage ratio. The property’s income story is central, while credit, value, leverage, reserves, and program rules still matter.
Often, personal income is not the main qualification test, so W-2s, pay stubs, and tax returns may not be required in the same way they are for a conventional loan. Lenders still review the borrower, the property, the entity, reserves, and other requested documentation. The exact file depends on the program and the deal.
As a rule of thumb, many DSCR lenders look for roughly 1.20 or higher, meaning the property’s rent is greater than its monthly debt payment. Some programs may consider a lower ratio with different leverage, pricing, reserves, or other conditions. The target is a guideline, not a guarantee of approval.
The down payment depends on property type, loan purpose, credit, DSCR, appraisal, and the program available for the deal. Many investors think in terms of loan-to-value: a 75% LTV structure, for example, implies 25% equity before closing costs and other adjustments. Your quote should show the actual leverage and cash needed.
Residential DSCR loans commonly cover 1–4 unit rentals, where market rent and the property’s value drive the review. Commercial DSCR loans generally cover 5+ unit multifamily, mixed-use, retail, office, and other larger income-producing properties, so leases, operating income, and property performance receive more attention.
A straightforward residential file may take roughly three to six weeks once the application, appraisal, and documents are moving. Commercial properties, unusual income, title questions, or a slower appraisal can take longer. The timeline depends on the deal and how quickly the needed information comes together.
