The Quick Read: A DSCR loan on a rental lends the smallest of three amounts: what the leverage cap allows on the lower of price or appraised value, what the appraised rent can carry at the coverage floor, and the program’s dollar ceiling. The sizing method is the same on any rental. Local inputs such as the rent the appraiser supports, taxes, insurance, and association dues change the result.
- Three gates, lowest wins. Leverage, rent coverage, and program size each produce a number, and the smallest one is your loan.
- Rent is the appraiser’s opinion, not your hope. On most files the counted rent is the lower of the signed lease and the appraised market rent.
- Typical purchase leverage is 75%–80% LTV on an investment property, subject to lender guidelines. Select high-leverage programs reach 85% with roughly a 700+ score.
- A bigger down payment lifts the ratio by shrinking the payment, but it never erases credit floors, reserves, or property rules.
- Clearing the ratio is not the same as positive cash flow. Repairs, vacancy, and management sit outside the calculation.
Why Is There No Single “How Much” Number?
A DSCR loan is sized by three separate tests, and the loan is whichever test gives the smallest answer. Two investors buying at the same price can walk away with very different loan amounts if their rentals rent differently.

As of Nov 5, 2026 · General Freddie Mac market benchmark, not a Lendmire loan offer. Rent, nightly rate, occupancy, taxes, and insurance are editable estimates. Short-term rental figures are estimates only and vary significantly by season, property type, management approach, and local short-term-rental rules — confirm local regulations before relying on them. Qualifying income for short-term rentals varies by program — some use appraisal market rent, others use documented STR history or projections — and is confirmed in underwriting. Not a Loan Estimate, approval, or commitment to lend. Program availability and eligibility are subject to lender guidelines, credit approval, property review, and underwriting.
The first test is leverage. Lenders cap the loan as a percentage of the lower of the purchase price or the appraised value. The second test is rent coverage. The rent has to cover the full monthly obligation at or above the program’s coverage floor. The third test is the program’s dollar band.
The dollar band is usually the least restrictive of the three. Standard programs in the wholesale network Lendmire works with go up to about $3,000,000, with smaller balances routed through select lenders. Most rentals hit the leverage or rent test long before that ceiling.
Rent coverage is one of three tests that together size the loan, and it can cap the amount on its own. Instead of simply passing or failing a loan the other two gates have already sized, the ratio works backward from the property’s rent to the largest loan that rent can support. The other two tests can still set a lower ceiling, and the smallest result controls.
How Underwriting Sizes the Loan, Step by Step
Underwriting follows the same path on nearly every file. Here is the sequence, in the order a lender actually works it.
Step 1: Pick the formula. On a one-to-four-unit residential rental, the ratio is the rent the lender counts divided by PITIA. PITIA is principal, interest, taxes, insurance, and association dues. A ratio of 1.00 means the rent equals the payment. A ratio of 1.25 means the rent is 25% larger than the payment.
Step 2: Order the appraisal. The appraisal does two jobs. It sets value, which drives the leverage test. It also gives a market-rent opinion, which drives the coverage test. For a one-unit rental, appraisers use the Single-Family Comparable Rent Schedule, known as Form 1007. For two to four units, they use the Small Residential Income Property Appraisal Report, known as Form 1025. Fannie Mae’s appraisal forms guide lists both. DSCR loans are not agency products, so those forms are borrowed conventions, not agency rules.
Step 3: Choose the rent number. On most files, the counted rent is the lower of the signed lease and the appraiser’s market rent. A vacant property uses market rent alone.
Step 4: Apply the leverage cap. The lender takes the lower of price or appraised value and applies the program’s LTV. If the appraisal comes in under the contract price, the loan sizes off the lower figure and the buyer covers the gap.
Step 5: Back into the rent-supported amount. Divide the counted rent by the coverage floor. That gives the largest PITIA the rent can carry. Subtract taxes, insurance, and dues. What remains is the most principal and interest the rent can support, and the lender converts that into a loan amount.
Step 6: Take the lowest of the three limits. Credit tier and reserves can then pull the cap down further.
Which Rent Number Actually Counts?
The appraiser’s market rent is the number that matters most, and a lease above it adds nothing. A lease below it drags the ratio down. Your pro forma, your neighbor’s rent, and the nightly rate on a booking site are not the number underwriting uses.
Picture two scenarios on the same duplex. In the first, the lease sits well under the appraiser’s rent because you signed a discounted lease to fill a unit. The lender counts the lease, and the loan shrinks. In the second, you renew at market before the appraisal. The counted rent rises, and so does the supportable loan.
This is why a conservative rent check before you write an offer pays off. If your offer assumes rent the appraiser will not support, the loan will come in smaller than you planned. You will then need more cash at the table.
How Much Leverage Do Lenders Allow?
On a purchase of an investment property, most files land at 75%–80% LTV, which means 20%–25% down. Select high-leverage programs reach 85% LTV on a purchase, which means 15% down. Those programs generally want a score around 700 or higher.
On a cash-out refinance of a standard rental, the ceiling is about 75% LTV across most of the network. Lenders commonly expect about six months of seasoning, the waiting period between buying and refinancing. If you want the deeper walkthrough, the cash-out refinance page covers it.
Credit works as a second leverage filter. A 620 floor exists in parts of the network. Most programs want around 660. Scores of 700 and up unlock the strongest leverage tiers. You can have a strong rent and still be capped by your score.
Loan size matters too. The standard band tops out around $3,000,000. Above $2,500,000, the network generally holds to 30-year fixed structures. Balances below the standard-program minimum route through select lenders instead of the standard programs.
What Does a Bigger Down Payment Do to the Loan?
A larger down payment shrinks the loan, which shrinks the payment, which lifts the ratio. The rent never changes. This is the cleanest lever on a deal that comes up short.
The table below shows direction and rough size. The percentages assume everything else holds constant, so treat them as illustrations, not quotes.
| Change | Effect on ratio | Effect on loan size |
|---|---|---|
| Appraised rent 10% lower | Ratio drops about 10% | Rent-supported amount shrinks |
| Taxes or insurance rise | Ratio drops | Rent-supported amount shrinks |
| Down payment up 5 points | Ratio rises | Leverage-capped amount shrinks |
| Interest-only period added | Ratio rises | Rent-supported amount grows |
Run one example in ratios. Say a rental clears about 1.10x. If the appraiser comes in with rent 10% lower, the ratio lands near 0.99x, just under 1.00. Now put five more points down. The payment falls, and the ratio climbs back above 1.00.
Notice what the extra cash does not do. It does not raise the leverage cap, lower the credit floor, or waive reserves. The strongest files clear both tests: enough equity and enough rental coverage.
What Structures Change the Math?
Several structures change how much the same rent can support. Each is a tradeoff, not a free upgrade.
Interest-only periods. During the interest-only period, the divisor becomes ITIA, which is taxes, insurance, dues, and interest only. That raises the ratio and lets the same rent support a larger loan. The cost is that principal does not shrink during that period. Interest-only terms are available through select lenders in the network.
Longer terms. The spine of the network is the 30-year fixed. Extended terms such as a 40-year structure are available through select lenders. A longer term lowers the payment and can lift the ratio. Lendmire’s piece How Much a Single-Family 40-Year DSCR Loan Lends on a Rental goes deeper on that structure.
Adjustable-rate structures. ARM structures exist for investors who want them. They suit investors with a defined hold period and a clear plan for the reset.
Coverage below 1.00. Many select programs start at 1.00. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Expect lower LTV and tighter terms on that path.
No-ratio structures. These are available only through select lenders, generally for borrowers who already own a primary residence. They run on different terms than standard files, so the pricing and leverage should not be assumed to match.
For the full picture of how these fit together, the complete DSCR loans guide walks through the program family.
Where Does the General Rule Break?
A lease that does not match the appraisal. A lease above market is capped at market. A lease below market pulls the ratio down. Check this before you sign a renewal, not after.
A low appraisal. If value comes in under the contract price, the loan sizes on the lower figure. The buyer funds the difference. Ask for a review only when you have comparable sales that support it.
Short-term rentals. Form 1007 reflects long-term rent. A nightly rate times 30 is not a valid market rent. Programs that count short-term rental income typically want about 12 months of hosting history and a score of 640 or higher. Purchase leverage tops out at 75% LTV. Refinance leverage runs around 70%, and a cash-out on short-term-rental collateral tops out at 70% LTV, versus 75% on standard rentals. A short-term rental purchase carries a 1.00 coverage floor, and a refinance carries its own 1.00 floor. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
Small loans. On smaller balances, some lenders add a higher coverage floor or lower leverage. Those files route through select lenders in the network instead of the standard programs.
Large loans. Reserves usually step up with loan size. Commonly they run about six months of PITIA, and about nine months on loans above $1,500,000. Conservative rate-and-term files at modest leverage under that size can see reserves waived. Reserves vary by lender, leverage, loan size, and transaction type, so treat any single number as a typical range.
Property type. Manufactured homes (single- and double-wide), log homes, and barndominiums are not offered in the network’s DSCR programs. If the property is one of these, the rent and the leverage never come into play. Condos and townhomes with HOA dues work, but the dues go into PITIA and shrink the loan.
Entity title. Many investors hold title in an LLC, subject to lender program eligibility. The guarantor’s credit and reserves still get reviewed.
DSCR vs. conventional financing
There are two common ways to finance an investment property, and they qualify you differently — here’s how investors weigh them.
Why investors choose it
- Qualifies on the property’s rental income — no personal tax returns, W-2s, or pay stubs needed to document income.
- No personal debt-to-income ceiling to clear, so existing mortgages and obligations don’t cap your borrowing the same way.
- Can be closed in an LLC, keeping the property inside a business entity.
- Built for scaling — not held to the limit on number of financed properties that conventional financing applies.
- Underwriting centers on the deal: generally qualifies when the rent covers the payment, a 1.00x coverage ratio being a common baseline (confirmed in underwriting).
- Designed specifically for investment property, including long-term and, where the program allows, short-term rentals.
Where it’s strong
- Often the lowest ongoing financing cost for a buyer who fully qualifies on personal income — a fit for a first property or a cost-first purchase.
Trade-offs for investors
- Requires full personal income documentation and must fit within a debt-to-income limit — salary, existing debts, and other mortgages all count.
- Typically held in your personal name rather than a business entity.
- Caps how many financed properties you can carry, which can become a ceiling as a portfolio grows.
- Evaluates you as a borrower as much as the property, which usually means more paperwork.
How investors usually choose: a first or single property often optimizes for the lowest financing cost; portfolio builders often optimize for leverage, vesting in an LLC, and scaling past conventional caps. The right answer depends on your goals, the property, and current guidelines — both paths run through select lenders in Lendmire’s wholesale network, with eligibility and terms confirmed in underwriting.
Why Does No Federal Loan Cap Apply?
Agency conforming limits apply only to loans the agencies buy, so they do not govern DSCR loans. DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.
The CFPB’s truth-in-lending exam material treats credit used to acquire or improve non-owner-occupied rental property as business-purpose credit. The purpose of the loan controls, not the label on the property, as Compliance Alliance explains. That is why sizing comes from lender guidelines rather than a statutory ceiling.
The practical result is that no personal debt-to-income ratio gets calculated. Self-employed investors and those with many financed properties can scale. But a loan sized on rent is still bound by leverage, credit, and reserves.
What Does the Decision Look Like in Practice?
Start with the rent, not the price. Estimate what an appraiser would support, run the ratio at the leverage you want, and see which gate binds. Then pick the lever that fixes the shortfall at the lowest cost to you.
| Lever | What it does | Tradeoff |
|---|---|---|
| More down payment | Lowers the payment and lifts the ratio | Ties up more cash |
| Lower purchase price | Cuts the loan and the taxes | May mean a different property |
| Interest-only period | Raises the ratio during that period | Principal does not shrink |
| Higher-rent unit type | Lifts counted rent | Different tenant and upkeep profile |
| Longer term | Lowers the payment | Slower principal paydown |
Clearing 1.00 is not the same as making money. A rental that clears about 1.20x on paper can still run thin once maintenance, vacancy, utilities, and management come out. The ratio compares rent to PITIA only, so size the loan to what the property can carry in a bad year, not just a good one.
Tax treatment varies; consult a qualified professional before relying on any deduction.
One last point on mindset. A lender’s maximum is a ceiling, not a target. Borrowing less than the cap leaves extra cushion, which makes a weak year easier to absorb.
Key Terms Defined
DSCR (debt service coverage ratio): The counted monthly rent divided by the monthly PITIA payment. It shows how many times the rent covers the loan.
PITIA: Principal, interest, taxes, insurance, and association dues. It is the full monthly obligation the rent must cover.
LTV (loan-to-value): The loan amount divided by the lower of price or appraised value. It caps how much you can borrow.
Form 1007: The appraisal rent schedule for one-unit rentals. It gives the appraiser’s market-rent opinion.
Form 1025: The small residential income property appraisal report for two to four units. It also includes rent information.
ITIA: Taxes, insurance, dues, and interest only. It replaces PITIA as the divisor during an interest-only period.
Seasoning: The waiting period a lender wants between buying a property and refinancing it.
Non-QM: Loans that fall outside the standard qualified-mortgage box. DSCR loans sit here.
Frequently Asked Questions
Can I borrow with a ratio below 1.00?
Sometimes. Many select programs start at 1.00, and a separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Expect lower LTV and tighter terms. Qualification is subject to lender guidelines, credit approval, and property review.
Does a bigger down payment raise or lower the loan size?
It lowers the loan and improves the ratio at the same time. A smaller loan means a smaller payment, so the same rent covers it by a wider margin. That can rescue a deal that fell short on coverage. It does not override credit floors, reserve rules, or property eligibility.
What if the appraiser’s rent is below my lease?
The lower figure usually counts. A lease above market adds nothing, because counted rent is capped at the appraiser’s number. If the ratio then falls short, you can put more down or restructure the loan to raise it. You can also ask the appraiser to review comparable rents, though the appraiser’s figure still governs unless it changes.
Can I buy the rental in an LLC?
Often yes, subject to lender program eligibility. The lender still reviews the guarantor’s credit and reserves. Ask before you sign a purchase contract in an entity name.
Do short-term rentals count the same way?
No. Form 1007 reflects long-term rent, and a nightly rate times 30 is not a valid market rent. Programs that count short-term rental income want documented hosting history and a 640+ score. Purchase leverage tops out at 75% LTV. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
