The Quick Read: On a $400K duplex, the check you receive is the smaller of two new loans, the equity-based loan and the rent-based loan, minus your existing payoff, closing costs, any prepayment charge on the old loan and required reserves. Most of that is set by the program, not by the headline number. The leverage ceiling caps the loan, not your proceeds.
- On a standard long-term rental duplex, cash-out leverage typically tops out around 75% LTV across most of the network.
- A short-term-rental duplex typically tops out at 70% LTV on a cash-out refinance.
- The new payment is larger than the old one, so coverage is re-tested. Modest rent can shrink the loan below the LTV cap.
- Seasoning of about six months from title recording is a common expectation, and reserves commonly run about six months of PITIA.
- Subject to lender guidelines, credit approval and property review, each file is underwritten individually. This is not a commitment to lend.
What Does a DSCR Cash-Out Actually Release?
A DSCR cash-out releases the difference between a new, larger loan and what you owe today, after costs come off. 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. Approval centers on the property’s rental income covering the payment, subject to lender guidelines, rather than on your personal paycheck.

Investors usually start from the wrong number. A $400K duplex does not put $300K in your pocket. That figure is the loan ceiling at 75% LTV on a standard rental, and the cash is whatever is left after the old loan is paid off and the costs are subtracted. Lendmire is a broker, so the guidance here reflects how files tend to size across the wholesale network of DSCR lenders it works with. The complete DSCR loans guide covers the full program picture.
Key Terms Defined
Appraised value: the value the lender’s own appraiser assigns, which is the number the LTV cap applies to. Your estimate of the property’s value after repairs is not an underwriting input.
LTV (loan-to-value): the new loan divided by the appraised value. A cash-out refinance is the line that applies whenever cash comes back at closing.
Payoff: the balance, including accrued interest and fees, needed to retire the existing loan.
PITIA: principal, interest, taxes, insurance and any association dues, which together make up the monthly obligation the rent is measured against.
DSCR (debt service coverage ratio): the property’s rent used for lender review divided by PITIA. A ratio above 1.00x means the rent covers the payment on paper.
Seasoning: how long you must have owned the property before a lender will size off appraised value instead of your purchase price.
Reserves: liquid funds held back after closing, commonly about six months of PITIA, which reduce the cash you can actually spend.
The Cash Formula, Line by Line
The formula has three steps, and every duplex file runs through them in the same order.
1. Find the maximum new loan. Take the lower of two figures: the LTV cap applied to appraised value, and the largest loan the rent can support at the program’s coverage floor.
2. Subtract the payoff. What remains is gross proceeds.
3. Subtract everything else. Closing costs, any prepayment charge on the old loan and any funds held back for reserves come out next.
In order of influence, the outcome depends on appraised value, the LTV cap for the property type, the payoff balance, whether the rent still covers the bigger payment, seasoning and value basis, reserves, and finally costs and prepayment charges. Most investors fixate on that last item, the costs and the prepayment charge. The first six decide the answer.
The $400K Duplex: Payoff Scenarios
Stating the room as a share of appraised value keeps the table portable. Multiply by your own appraisal to see the dollar figure. All rows assume the full loan the LTV cap allows, before costs, reserves and the rent test.
| Existing payoff (% of value) | Gross room, standard rental at 75% | Gross room, STR duplex at 70% |
|---|---|---|
| 50% | 25% of value | 20% of value |
| 60% | 15% of value | 10% of value |
| 70% | 5% of value | None, payoff only |
| 75% | None, payoff only | Cash needed at closing |
The 75% row is the one investors overlook. A duplex with a payoff at the ceiling can be refinanced, but the loan works as a payoff, not as a source of cash. If the payoff sits above the cap, the borrower brings cash to closing. A standard long-term rental duplex taps the 75% column, while a short-term-rental duplex typically sits at the 70% column. Some programs in the network trim leverage further on two-to-four-unit collateral, so treat 75% as a ceiling and not a promise.
The Rent Test on the Same Duplex
Rent can override leverage. Taking cash out raises the payment, which lowers the coverage ratio, and the lender sizes the loan to the tighter of the two tests. On a duplex, qualifying income is the appraiser’s market rent across both units combined, measured against PITIA on the new loan. Rent used for lender review comes from the appraisal, not from a listing’s optimistic projection.
Run the numbers two ways on the $400K duplex.
Equity binds. Say the full 75% loan tests at roughly 1.25x coverage. The rent has room to spare, so the LTV cap sets the loan. Your gross room is simply 75% of value minus the payoff, and the table above applies.
Rent binds. Say the full 75% loan tests at about 0.95x. Where the program starts coverage at 1.00, the loan shrinks until rent supports it. Because payment scales roughly with loan size, the supportable loan lands near 71% of value, about four points of value below the cap. Those four points come straight out of your cash. On a thin-equity file, it can erase the cash entirely.
This is the usual duplex trap: strong equity, average rents. Two other paths exist:
- Coverage of 1.00 is where many select programs start. A separate path through select lenders in the network takes coverage below 1.00, with leverage and terms adjusted. Adjusted leverage means less cash back, so it solves approval more than it solves proceeds.
- Raising rent through renewals, or documenting a stronger appraised market rent, lifts coverage and loan size together.
Whether a vacant unit tests at market rent or at zero varies by lender, so a half-empty duplex is worth raising early in the conversation.
What Comes Off the Check
| Item | How it affects your cash |
|---|---|
| Existing payoff | Comes out first, including accrued interest |
| Closing costs | Reduce the wire, vary by loan size and file |
| Prepayment charge | Applies if the old loan carries one |
| Funded escrows | Prepaid taxes and insurance, if collected |
| Reserve holdback | Cash you must keep, so it is not free capital |
The last row matters most for planning. A wire that clears does not equal usable capital if the program requires about six months of PITIA in reserves. Reserves vary by lender, leverage, loan size and transaction type, and loans above $1,500,000 typically step up to about nine months. Some conservative rate-and-term files at modest leverage can see reserves waived, but a cash-out is the transaction where reserves are most likely to apply.
A prepayment charge on the old loan deserves a line in your model. Hard-money and bridge loans often carry one, and a payoff that returns cash to you counts as a cash-out for seasoning purposes.
What Moves the Number
Small changes in three inputs reshape the result on a duplex, because the cash is a thin slice of value.
| Input that moves | Effect on a cash-out at 75% LTV |
|---|---|
| Appraisal comes in lower | Each 1% drop cuts the maximum loan by 0.75% of the original value |
| Rent supported by the appraiser falls | May shrink the loan below the LTV cap |
| Payoff rises or balance is higher | Cuts gross room point for point |
An appraisal miss of 5% lowers the loan ceiling by about 3.75% of the original value. On a file with 5% gross room at the start, that single miss can wipe out the proceeds. On a file with 25% room, it is a haircut. The thinner the slice, the more the appraisal decides.
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.
Duplex-Specific Underwriting
A duplex is underwritten on the two-to-four-unit appraisal form, which agency lending calls the Form 1025 Small Residential Income Property Appraisal Report. A single-family rental instead uses a one-unit form with a separate rent schedule. DSCR loans themselves are non-agency products, so the form names are borrowed for the appraisal only and the agency rules do not govern the loan. What matters for you is that the 1025 includes an operating income statement with unit-level rents, which is the rent evidence the lender sizes from.
Across Lendmire’s network, the pattern on duplex files is consistent. The appraisal rent drives the loan size more than any other single input, and investors who bring both lease copies and a clear picture of market rent for each unit run into fewer surprises.
Some properties are outside the program altogether. Manufactured homes (single- and double-wide), log homes and barndominiums are not offered through the network’s DSCR programs, so a duplex built that way would not reach this table.
Eligibility Checks That Decide Whether You Get Any Cash
- Seasoning. About six months of ownership from title recording is the common expectation. It is lender policy, not law. Inside that window, a lender may size off what you paid rather than appraised value.
- Delayed financing. If you bought with cash, a delayed-financing structure can waive seasoning. The payout is typically capped near your documented purchase cost, not full current value.
- Credit. 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.
- Property occupancy. The property must be a non-owner-occupied rental. A duplex where you live in one unit is a different product.
- Entity paperwork. The loan documents, insurance and existing mortgage statement should match the name on title. Mismatches are a common source of delay at the closing table.
- Loan size. Standard programs run up to $3,000,000, and smaller balances route through select lenders in the network.
A short-term-rental duplex adds its own screen: typically a 640+ score, about 12 months of hosting history, and cash-out leverage capped at 70% LTV. 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.
After Closing: Payment, Coverage and Cash Flow
Taking cash out does not come free, and the cost shows up every month. The new loan is larger, the payment goes up, and the coverage ratio you had at purchase no longer applies. A ratio that clears 1.00x is not the same as positive cash flow. DSCR compares rent to PITIA only, so repairs, vacancy, management, utilities and capital expenses sit outside the calculation.
Before you take the cash, ask what the money will do. Cash deployed into another rental whose own coverage clears the test is a defensible use. Cash used to cover a negative-carry property just moves the problem. Tax treatment varies; consult a qualified professional before relying on any deduction.
If the Number Comes in Smaller Than Expected
Several moves can lift the result without forcing a worse structure.
1. Wait out seasoning. If you are still inside the six-month window, appraised value may not be available as the sizing basis yet.
2. Document stronger rent. Renewals at current market rents and clean leases support the appraiser’s figure.
3. Pay down the existing balance. Reducing the payoff widens gross room point for point.
4. Revisit the structure. An interest-only period or an extended term, both available through select lenders in the network, can lift coverage when rent is the binding limit. Neither changes the LTV cap.
5. Skip the refinance. If the gross room is a few points of value, costs and reserves may leave almost nothing. A smaller-than-expected number is sometimes the answer that says to leave the existing loan alone.
Frequently Asked Questions
Does a $400K duplex at 75% LTV mean I get $300K?
No. The 75% figure is the ceiling on the new loan for a standard long-term rental, not your proceeds. The existing payoff, closing costs, any prepayment charge and required reserves all come out first. Your actual cash is typically a fraction of that ceiling, and it can be zero when the payoff is close to the cap.
Which limit usually binds first, equity or rent?
On duplexes with average rents and strong equity, coverage often binds first. Cash-out raises the payment, which lowers the ratio, and the lender sizes to whichever test is tighter. On files with high rents and thin equity, the LTV cap binds instead. Running both tests before you apply tells you which one is yours.
Can I do a cash-out if I just bought the duplex?
Usually, but the value used differs. About six months of seasoning from title recording is the common expectation across the network, and inside that window the lender may size off your purchase price rather than the appraisal. Delayed financing after an all-cash purchase waives seasoning only, and the payout is typically capped near your documented cost.
Do I need to live in the duplex or show income documents?
DSCR loans are for non-owner-occupied investment properties, so a duplex you occupy falls outside them. The file qualifies primarily on property-level rental income covering the payment, subject to lender guidelines, with credit and reserves still reviewed. Lenders may still ask for entity documents and insurance, so expect paperwork even without personal income documents.
What if my duplex’s rent doesn’t cover the new payment?
At 1.00 coverage, where many select programs start, a shortfall shrinks the loan until rent supports it. A separate path is available through select lenders in the network for coverage below 1.00, with leverage and terms adjusted, which usually means less cash back. Raising documented rent or paying down the balance first often helps more than changing the structure.
