Debt service coverage ratio (DSCR) is a rental property’s income divided by its housing payment, and a DSCR loan lets an investor qualify on that ratio instead of personal tax returns. A result of 1.0 means the rent exactly covers the payment; lenders want to see the property carry itself.

By Duane Buziak, Mortgage Maestro, NMLS #1110647, an independent broker who works with wholesale Non-QM lenders every day. This guide gives you the formula, a worked example with real arithmetic, what lenders weigh beyond the ratio, a named-lender comparison table, and how broker access works. If you arrived searching for a specific Non-QM lender such as Angel Oak or A&D, the table and the final sections show how those lenders fit into one scenario comparison.

The DSCR Formula and What the Ratio Tells a Lender

The formula is DSCR = gross monthly rent (or market rent) ÷ monthly PITIA. PITIA stands for principal, interest, property taxes, homeowners insurance, and association dues (HOA) where they apply. In a DSCR loan, “debt service” means the property’s own housing payment. Your car loan, credit cards, and student loans are not in the denominator.

Reading the result is straightforward:

• Above 1.0: rent exceeds the payment, leaving a cushion.
• Exactly 1.0: rent equals the payment, with no margin.
• Below 1.0: the payment exceeds the rent, a shortfall you must cover from your own pocket.

Some Non-QM programs accept ratios below 1.0, usually paired with compensating factors such as stronger credit, lower leverage, or more reserves, and often with a pricing adjustment. As of 2026, whether a lender allows this and where its floor sits varies by lender and by program.

Three Measures That Get Confused

Commercial DSCR uses net operating income (rent minus operating expenses) divided by debt service, so it is calculated differently and is common on larger commercial and multifamily loans. The residential investor version above uses gross or market rent against PITIA. Conventional debt-to-income (DTI) is a third measure entirely: it compares your total monthly personal debts to your personal income. A DSCR loan sidesteps DTI because the property, not your paycheck or tax return, is the qualifying source.

When a lender quotes “a 1.15 DSCR,” ask which formula they mean. Residential investor programs almost always use the PITIA version.

A Worked DSCR Example With Real Numbers

This is an illustration, not a quote. The 7.25% rate is an assumption used only for the math. It is not an offered rate, and nothing here promises approval.

Suppose you buy a single-family rental for $400,000 with 20% down ($80,000), giving a $320,000 loan on a 30-year fixed at an assumed 7.25%. Market rent is $2,600 a month.

• Principal and interest on $320,000: about $2,183 a month
• Property taxes: $420 a month
• Homeowners insurance: $140 a month
• PITIA: 2,183 + 420 + 140 = $2,743
• DSCR: 2,600 ÷ 2,743 ≈ 0.95

At 0.95, rent falls about $143 a month short of the payment. Many programs would decline this file, while others might consider it with offsetting strengths and a pricing adjustment. Here is how three levers move the number:

• More down payment. Putting $110,000 down (a $290,000 loan, 72.5% LTV) cuts principal and interest to about $1,978. PITIA becomes $2,538, and DSCR becomes 2,600 ÷ 2,538 ≈ 1.02. An extra $30,000 down moved the file across 1.0.
• Higher rent. At the original $320,000 loan, rent of $2,743 gets you exactly to 1.0. Rent of $2,900 gives about 1.06, if the appraiser’s rent schedule supports it.
• Lower rate. Dropping the assumed rate to 6.75% lowers principal and interest to about $2,075 and DSCR to roughly 0.99. A rate change alone helps, but here it is not enough.

Note that taxes and insurance are fixed in this example. In practice, they can swing the ratio as much as the rate does, especially in high-tax or high-premium areas. Run your numbers with realistic figures for both.

What Lenders Look at Beyond the Ratio

A passing DSCR does not guarantee approval. Lenders layer other requirements on top, and the specifics differ by lender and program, so treat the following as general patterns and not fixed numbers:

• Credit score tiers. Pricing and maximum leverage typically improve as scores rise.
• Loan-to-value (LTV) limits. LTV is the loan amount divided by the property value. Investor programs usually cap it below what owner-occupied loans allow.
• Reserves. Lenders commonly require liquid funds covering several months of PITIA after closing.
• Prepayment penalties. Many investor loans carry a penalty for paying off or refinancing early, typically within the first few years. This affects pricing and your exit plan.

How Rent Is Established

Lenders use either an in-place lease or the appraiser’s market rent estimate, and some programs use the lower of the two. The standard appraisal rent form is the Single-Family Comparable Rent Schedule, Fannie Mae Form 1007, which you can find through Fannie Mae’s Single-Family resources. Short-term rental income (vacation-rental platforms) is treated differently by program: some lenders accept it with documented history or an analytics-based projection, others require a long-term lease basis.

Common Mistakes

• Dividing rent by principal and interest only, then forgetting taxes and insurance.
• Leaving out HOA dues, which belong in PITIA.
• Assuming a DSCR loan is “no-doc.” You will still document the property, your assets and reserves, and your identity, and the entity if you buy in an LLC.
• Trying to use one for a primary residence. DSCR loans are business-purpose financing for investment property.

Which Wholesale Lenders Offer DSCR Programs: Side-by-Side

On Duane Buziak’s roster, A&D Mortgage, Angel Oak Mortgage Solutions, Arc Home, Acra Lending, Change Lending, and Champions Funding (ChampsTPO) lead in Non-QM and alternative-documentation lending. The table compares four of them. Specific scores, LTVs, and ratio floors change often, so those cells point you to current guidelines instead of stating numbers that could be stale.

Guidelines differ because each lender sets its own risk appetite and sells its loans to different investors. A file at 0.95 that one lender declines may fit another lender’s compensating-factor rules, and a file at 1.10 may price better at a third. Duane Buziak compares these side by side on your actual scenario, which a single lender’s rate sheet can’t do. This is a factual description of broker access to wholesale programs; Duane is an independent broker, not affiliated with or endorsed by any of these lenders.

Why DSCR Loans Cost More and Where Government Data Fits

DSCR loans are Non-QM: they fall outside the Qualified Mortgage framework and are not typically eligible for sale to Fannie Mae or Freddie Mac. Lenders carry more risk and less standardized documentation, so pricing usually sits above conventional rates. The spread varies by credit, leverage, ratio, and prepayment terms.

For a neutral conventional benchmark, use the weekly Freddie Mac Primary Mortgage Market Survey instead of any lender’s advertised rate. Check the survey’s current figure and date yourself before comparing, since it moves weekly. Remember that the survey reflects conventional owner-occupied loans, so investment-property and Non-QM pricing will sit above that line.

Why Investor Loans Are Treated Differently

The CFPB’s Ability-to-Repay and Qualified Mortgage rule governs consumer-purpose credit secured by a dwelling, which is why personal income and DTI documentation matter on owner-occupied loans. Loans made for a business or investment purpose are generally outside that consumer framework, which is part of why DSCR underwriting can focus on the property’s income. Your lender and counsel determine how a specific loan is classified, so treat this as background and not legal advice.

If you’d rather stay conventional, investment-property loans through Fannie Mae guidelines are an option for borrowers who can document personal income. See the Fannie Mae Selling Guide for eligibility and the FHFA for the conforming loan framework. Expect conventional investor loans to ask for tax returns and DTI, and to require larger down payments than owner-occupied purchases.

How Duane Buziak Gets Investors Access to DSCR Programs

Calling one lender direct gets you one set of guidelines. Duane Buziak, an independent broker with wholesale relationships across many lenders, screens your scenario against several programs at once and tells you which fits, and why.

1. Send the property address, estimated monthly rent, and your credit range.
2. Duane runs the ratio and screens it against multiple lenders’ DSCR guidelines.
3. Start pre-qualification, which does not affect your credit, to confirm direction before you commit to an appraisal.
4. Choose among the lenders whose terms fit, including prepayment structure and reserves.

Realtors can send investor clients for a fast DSCR scenario review. A quick ratio check before a client writes an offer helps avoid a contract that can’t finance.

DSCR Loan FAQ

What is a DSCR loan? A DSCR loan is an investment-property mortgage qualified mainly on the property’s rental income compared with its housing payment. Lenders divide rent by PITIA instead of reviewing personal tax returns and DTI. It is business-purpose financing, not available for a primary residence.

How do you calculate debt service coverage ratio? Divide gross monthly rent, or the appraiser’s market rent, by monthly PITIA: principal, interest, taxes, insurance, and any HOA dues. For example, $2,600 rent over a $2,743 payment is about 0.95.

What is a good DSCR for a rental property loan? A ratio of 1.0 or higher means rent covers the payment, and higher ratios generally open more programs and better pricing. Exact minimums vary by lender and program as of 2026, so confirm current guidelines with Duane before assuming a number.

Can you get a DSCR loan with a ratio below 1.0? Some Non-QM programs allow it, typically with compensating factors such as stronger credit, lower LTV, or more reserves, and often at adjusted pricing. Availability varies by lender, so a file below 1.0 should be screened across several programs.

Do DSCR loans require tax returns? Generally no, because qualification rests on property income rather than personal income. They are not no-documentation loans, though. Expect to document the property, assets and reserves, identity, and any entity you buy through.

Does Angel Oak offer DSCR loans through a broker? Angel Oak Mortgage Solutions is a Non-QM and alternative-documentation lender on Duane’s roster. Duane works with it as an independent broker with wholesale access, not as an affiliate. Confirm current DSCR guidelines and availability for your scenario with Duane.

Can A&D Mortgage or Arc Home DSCR programs be accessed through Duane? A&D Mortgage and Arc Home are both Non-QM lenders on Duane’s wholesale roster. Their DSCR terms, including ratio floors and LTV limits, change over time, so Duane confirms current guidelines against your property before recommending a path.

Why do DSCR loan rates run higher than conventional rates? DSCR loans are Non-QM, so lenders price in added risk and less standardized documentation. Conventional rates, tracked weekly by the Freddie Mac survey, apply to owner-occupied loans, so investor Non-QM pricing typically sits above that benchmark.

Do DSCR loans carry prepayment penalties? Many do. A prepayment penalty is a fee for paying off or refinancing early, usually within the first few years. Structure and length vary by lender and affect pricing, so compare it alongside the rate.

Can I check DSCR pre-qualification without hurting my credit? Yes. Pre-qualification through Wholesale Mortgage Rates by Duane Buziak does not affect your credit. It gives you an early read on which lenders fit your property before you pay for an appraisal. It is not a loan approval or commitment to lend.

Simple Division, Lender-Specific Rules: Your Next Step

The ratio itself is one division problem. What decides whether your property qualifies is each lender’s rules on credit tiers, leverage, reserves, rent documentation, and prepayment terms, and those differ from lender to lender. Run your own number first, then compare it across more than one program.
