The Quick Read: A DSCR cash-out refinance on a $400K duplex is sized by the tighter of two limits, either about 75% of appraised value on a standard long-term rental (70% on short-term-rental collateral) or the largest loan the combined rent can support, with your payoff and costs coming out of the result.
- The value limit is appraised value times the cash-out LTV cap. Across most of Lendmire’s wholesale network, that cap tops out around 75% on a standard rental.
- The rent limit is the biggest loan whose full payment the duplex’s combined rent can cover at the required coverage ratio.
- Cash to you is the new loan minus your payoff, closing costs, and any prepayment charge on the old loan.
- Cash-out does not guarantee cash. A payoff at or near the 75% cap can leave nothing.
- Program details change, and every file is underwritten individually by the lender, subject to lender guidelines.
Here is the part most investors miss. The question “how much will it lend” has no single dollar answer. It has a formula, and your payoff balance and your rents fill it in.

Key Terms Defined
DSCR (debt service coverage ratio): monthly rent divided by the full monthly payment on the property. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
LTV (loan-to-value): the loan amount as a percentage of the property’s appraised value.
PITIA: principal, interest, taxes, insurance, and any HOA dues. It is the full monthly payment the rent must cover.
Seasoning: the waiting period between buying a property and refinancing it, measured from the date title was recorded.
Gross cash versus net cash: gross cash is what the value limit allows before costs. Net cash is what reaches you after payoff, costs, and any prepayment penalty (a fee some loans charge for paying them off early).
Rate-and-term refinance: a refinance that changes the loan’s structure but returns no cash at closing.
The Formula: Two Limits, One Loan
The loan is the lower of the value-limit amount and the rent-limit amount. Neither one alone decides it.
The value limit is simple. Take the appraised value and multiply by the cash-out LTV cap. On a standard long-term-rental duplex, that cap tops out around 75% across most programs we place files with. Short-term-rental collateral caps at 70% on a cash-out. An individual lender can set a lower number.
The rent limit is the one that surprises people. Underwriting takes the rent from both units, adds it together, and tests it against one payment for the whole building. That payment is the full PITIA on the new, larger loan. A bigger loan means a bigger payment, so coverage falls as you pull more cash.
Then comes the subtraction. Payoff, closing costs, reserves, and any prepayment charge come out of the loan. What remains is your net cash.
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.
What a $400K Value Allows
The table below shows the value limit alone. It uses percentages of the $400K value, so you can scale it to your own payoff. It is an illustrative sketch, not a quote, and it ignores costs and reserves.
| Payoff as % of value | Gross cash at 75% (standard rental) | Gross cash at 70% (STR collateral) |
|---|---|---|
| 30% | 45% of value | 40% of value |
| 50% | 25% of value | 20% of value |
| 60% | 15% of value | 10% of value |
| 70% | 5% of value | Nothing left |
Read the bottom rows twice. A duplex with a payoff near the cap has almost no cash to give, even if the appraisal comes in strong. Closing costs alone can erase a thin margin. The editable calculator on this site turns these percentages into dollars as an illustrative estimate.
How Underwriting Treats the Duplex, Step by Step
Step 1: Seasoning
The lender checks how long you have held title. About six months is the common expectation across the network. Seasoning is lender policy, not law, so it varies by program.
Inside that window, the loan is typically sized on the lower of appraised value or your cost basis. After it, the appraisal governs. Waiting longer does not raise the LTV percentage. It only lets the appraisal count.
Step 2: The Appraisal and Rent Schedule
A duplex is appraised on Form 1025, the Small Residential Income Property Appraisal Report. Fannie Mae’s Selling Guide lists it as the form for two- to four-unit properties, and Fannie Mae’s form text says the same. The form captures rent for each unit.
Form 1007, the single-family rent schedule, is a different form. The Selling Guide ties it to one-unit investment properties. DSCR programs do not follow agency loan rules, and agency caps and haircuts do not apply to these files.
Step 3: The Coverage Test
Market rent from both units is divided by PITIA on the new loan. A 1.00 ratio means rent equals the payment. Many select programs start at 1.00, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. For borrowers who already own a primary residence, a no-ratio path exists only through select lenders.
Step 4: The Rest of the File
Credit comes next. A 620 floor exists in parts of the network, and most programs want around 660. A score of 700 or higher unlocks the strongest leverage tiers.
Reserves are cash you hold after closing. They vary by lender, leverage, loan size, and transaction type. About six months of PITIA is common, and loans above $1,500,000 typically step up to about nine months. Standard programs go up to $3,000,000.
If the duplex sits in an LLC, expect an entity package: articles of organization, operating agreement, EIN letter, and a good-standing certificate. LLC borrowers are subject to lender program eligibility.
Step 5: The Result
The lender takes the lower of the two limits. Payoff, costs, and reserves come out. What remains is yours. For the wider mechanics, Lendmire’s complete DSCR loans guide covers the full process.
When Rent, Not Equity, Sets the Loan
On many duplexes, the rent limit binds first. You can pass the LTV test and still fail the rent test.
The next table is a modeled sketch. It shows what happens when the loan sized to the value limit meets different rent levels. The coverage ranges are assumptions, not market data.
| Combined rent (both units) | Coverage at full value-limit loan | Which limit binds |
|---|---|---|
| Weak | Below 1.00x | Rent limit |
| Average | Around 1.00x to 1.15x | Close call |
| Strong | 1.25x or higher | Value limit |
With weak rent, the loan has to shrink until coverage clears the program’s floor. Cash shrinks with it. A select-lender path with coverage below 1.00 may be an option. Leverage and terms adjust on that path, and approval is subject to lender guidelines and property review.
Taxes and insurance matter here as much as rent. They sit inside PITIA, so a high-tax or high-premium duplex shrinks loan capacity the same way low rent does. That can be the whole story on an equity-rich property.
On a duplex whose value rose sharply, the cash-out can come up well short of the equity. That is the rent test talking, not the appraisal.
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.
Structures and Variations
Short-term-rental duplex. Cash-out caps at 70% on short-term-rental collateral. Expect a 640+ score and about 12 months of hosting history, with a 1.00 coverage floor on refinances. 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.
Rate-and-term instead of cash-out. If you only need to restructure, this route returns no cash and reaches up to 85% LTV on select programs. A payoff-only refinance of a short-term bridge loan may be classed as rate-and-term. If any cash comes back at closing, the lender treats it as a cash-out.
Term structures. The spine is the 30-year fixed. Select lenders in the network offer 40-year terms and interest-only periods. ARM structures exist for investors who want them. Above $2,500,000, the network generally holds to 30-year fixed.
Second liens. Adding a second loan behind the first does not raise the ceiling, because the combined balance still counts against the same value limit, and less cash is left once both balances are covered. A commenter in a BiggerPockets discussion on DSCR cash-out options says coverage must still hold after both payments. That is one investor’s account, not a program rule. The same thread notes that pushing leverage higher costs more in pricing. Across Lendmire’s network, a standard rental cash-out tops out around 75% LTV, whatever the lien structure. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Where the General Rule Breaks
Inside the seasoning window. A big appraisal bump will not carry the loan. It is sized on cost basis. A delayed-financing approach waives only the waiting period. Everything else, including coverage, credit, and reserves, still applies.
Refinancing out of an existing DSCR loan. Many carry a prepayment penalty. That charge comes straight out of your net cash. Read the old note before you model the new one.
Very large balances. The conforming loan limit does not cap a DSCR loan. Programs set their own size limits, and very large balances can trigger a second appraisal.
Owner-occupied duplexes. If you live in one unit, a DSCR loan is usually not the fit, because these programs target non-owner-occupied rentals. A conventional product handles that case.
Ineligible property types. Manufactured homes, log homes, and barndominiums are not offered in the network’s DSCR programs. A duplex built that way will not fit.
Clearing 1.00 Is Not Positive Cash Flow
DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation.
A duplex that tests at exactly 1.00 is at break-even on the loan payment alone. After a cash-out, it may run thin on real-world cash flow. Run your own numbers with those costs included before you decide how much to pull. A smaller draw can be the stronger play, even if the lender would allow more.
Ways to Raise the Cash
- Document the rents. Signed leases and a clean appraisal rent schedule support the coverage test.
- Pay down the balance. A lower payoff raises gross cash under the value limit and lowers the new payment.
- Improve credit. Moving up a credit tier can lift the leverage available to you.
- Wait out seasoning. Waiting does not raise the LTV percentage. It lets the appraisal govern instead of cost basis.
- Shop several lenders. Guidelines and reserves differ across the network, and the right match can change the outcome.
A larger down payment lowers the payment and can lift coverage. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests, enough equity and enough rent.
Frequently Asked Questions
Can I get 80% LTV on a duplex cash-out?
On Lendmire’s network, a cash-out refinance tops out around 75% LTV on a standard long-term rental. The 80% figure belongs to purchases, not cash-outs. Individual lenders may set lower limits. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
What if my duplex’s payoff is close to the cap?
Then the net cash can be small or zero. The value limit leaves little room, and closing costs and reserves come out of what remains. In that case, a rate-and-term refinance may serve you better if your goal is restructuring rather than cash.
Do cash-out proceeds count toward reserves?
It depends on the lender and program. Reserves are typically about six months of PITIA, stepping up to about nine months above $1,500,000. Some programs let cash from the refinance count, and others want reserves held separately. Confirm with the lender during file review.
Will a higher appraisal always give me more cash?
No. Rent can cap the loan even when value is high. You can pass the LTV test and fail the coverage test. A strong appraisal helps only if rent also supports the larger payment.
Do I need personal income documents?
Personal income documents are not central to these programs. The file runs on appraisal, rent support, entity papers if applicable, credit, and reserves. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
Next Steps
Start with three numbers: your appraised value, your payoff, and the combined rent on both units. Apply the 75% value limit, subtract the payoff, then test whether rent can carry the bigger payment.
