The Quick Read: Run two tests side by side: equity sets the biggest loan you can take, rent coverage sets the biggest payment the whole building can carry, and the smaller loan governs, leaving net cash after the payoff, closing costs, and any required reserves.
- Equity test: appraised value times the leverage cap. On a cash-out refinance of an investment property, most programs in Lendmire’s wholesale network top out around 75% LTV.
- Rent test: combined unit rents divided by the full new payment on the building. Many select programs start at 1.00 coverage, and stronger ratios open better terms.
- Net cash: new loan, minus payoff, minus costs. Nothing guarantees a positive number.
- Clearing the ratio is not the same as cash flow. Repairs, vacancy, management, and utilities sit outside the calculation.
What Is the Math Actually Solving?
A cash-out refinance replaces your current mortgage with a bigger one, and you keep the difference. Two limits decide how big the new loan can be. One looks at equity. The other looks at rent. Most investors only run the first test, and that is where the surprises start.

Picture a fourplex with plenty of equity but soft rents. The equity math says you can pull a lot. The rent math says the building can’t carry the payment that loan would create. The rent math wins, and the cash shrinks.
DSCR stands for debt service coverage ratio. On a residential 1-4 unit DSCR loan, you get it by dividing monthly rent by the full monthly housing payment. That payment is called PITIA: principal, interest, taxes, insurance, and association dues. The lender checks whether the rent covers that payment. That is the whole idea. The complete DSCR loans guide covers the basics if the term is new to you.
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. That matters on a 2-4 unit, because a house-hacker living in one unit is playing a different game than an investor who rents all of them.
Key Terms Defined
LTV (loan-to-value): the new loan divided by the appraised value. A 75% cap limits the whole loan, not your equity.
Payoff: the full balance you must clear at closing, including any second lien.
PITIA: the full monthly housing payment: principal, interest, taxes, insurance, and association dues.
Coverage ratio (DSCR): monthly rent divided by PITIA. Above 1.00 means rent exceeds the payment on paper.
Seasoning: the waiting period between buying a property and cash-out refinancing it. About 6 months of ownership, counted from title recording, is the common expectation across the network.
Reserves: liquid assets you show after closing. Commonly that means about 6 months of PITIA, though it varies by lender and loan size.
Net proceeds: the cash that actually reaches you after every deduction.
Step 1: Set the Value
Value is the input everything else multiplies. Use the appraisal, not the purchase price and not your projected value after repairs. Your own estimate is a planning number only.
Seasoning decides which value applies. Some programs lend off the original purchase price in the early months and a fresh appraisal later. Others use a new appraisal once the seasoning period is met. Ask which basis applies before you plan the deal.
On a 2-4 unit, the appraiser also reports rent. The standard way to do this is on Fannie Mae’s Form 1025, the Small Residential Income Property Appraisal Report, which is built for two- to four-unit buildings. Its single-family cousin is Form 1007, a comparable rent schedule. These are agency forms, and DSCR loans are not agency products. Each DSCR program sets its own report requirements. The forms are useful here only as a picture of what the appraiser’s rent opinion looks like.
Step 2: Run the Equity Test
The formula is short: value times the LTV cap gives the maximum loan. Then subtract what you owe and the costs.
Across most of the network, a cash-out refinance of an investment property tops out around 75% LTV. A purchase of an investment property usually lands at 75% to 80% LTV, so cash-out is the tighter box. Short-term rentals run lower: a cash-out on short-term-rental collateral caps at 70%, while a standard rental cash-out caps at 75%.
Here is the mistake people make. “75% LTV” does not mean you can take 75% of your equity. The cap applies to the total loan against value. If you owe a lot, most of that 75% goes to clearing the old loan before you see a dime. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
The same goes for a second lien. A HELOC or home-equity loan on the building must be paid off or counted. It is part of the payoff.
Step 3: Run the Rent Test
On a 2-4 unit, you add the rents of every unit and set them against one payment on the whole building. One building, one mortgage, one coverage ratio.
Now build the new payment. The principal and interest come from the new, larger loan, not your old payment. Taxes, insurance, and dues come from current bills. Using last year’s tax figure or an expired insurance policy overstates your coverage. Lenders pull the current numbers anyway.
Which rent counts? Programs differ. Many use the lower of the signed leases and the appraiser’s market rent. A lease sitting below market can therefore cap your ratio at the lease. Vacant units are a split decision. Some lenders credit the appraiser’s market rent on an empty unit. Others hold it at zero until a lease is signed. Know which one your lender uses before you count on that unit.
Investor-education site Arrived explains that coverage tells you whether a property’s income covers its debt, and that lenders use it to size the maximum loan on a new loan or refinance. Its version uses net operating income over debt service, which is the commercial formula. Residential DSCR programs use rent over PITIA instead. That is a simpler test, and a less forgiving one in one respect: it ignores your operating costs entirely.
Reverse-solving the loan
You can work the test backward. Pick a target coverage, say 1.20. Divide 1 by 1.20 and you get about 0.83. That means the full payment can run about 83% of rent. Subtract taxes, insurance, and dues, and what’s left is the room for principal and interest. That room converts to a maximum loan.
Notice the catch. Taxes and insurance don’t shrink when the loan does. So when coverage falls short, the principal-and-interest piece absorbs the entire cut. The loan has to drop by more than the shortfall percentage suggests.
Step 4: Take the Smaller Loan
Run both tests. Whichever produces the smaller loan governs. Here is how the two outcomes look.
| Situation | Binding test | What it means |
|---|---|---|
| Strong rent, modest equity | Equity (LTV cap) | Coverage clears; cash is limited by 75% |
| Thin rent, plentiful equity | Rent coverage | Loan shrinks until payment fits rent |
| Low appraisal | Equity | Payoff is fixed, so cash drops hard |
Coverage floors matter here. For many select programs, 1.00 is where eligibility starts. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios generally open better pricing and leverage. Everything remains subject to lender guidelines, credit review, and property review.
Step 5: Build the Net-Cash Waterfall
The new loan is not your cash. Subtract the payoff, closing costs, prepaid items such as the first tax and insurance deposits, and any prepayment charge on the loan you’re retiring. Check reserves too. Whether proceeds can count toward reserves depends on the lender.
Closing costs vary by lender, loan size, and state, so treat them as a real line item in your math rather than a rounding error.
Run the arithmetic in plain units instead of dollars. These are modeled assumptions, not market facts. Say a fourplex appraises at 100 units of value.
- Maximum loan at 75% LTV: 75 units.
- Payoff, including any second lien: 52 units.
- Closing costs and prepaids: 3 units.
- Net cash: 75 − 52 − 3 = 20 units. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
That is the equity test. Now the rent test on the same building, again as a modeled assumption. Before the refinance, coverage was about 1.45x. At the new 75-unit loan, with taxes and insurance unchanged, it lands near 1.09x. It clears 1.00 with limited cushion.
Now flip the rent. Suppose the same building has softer rents and coverage at the 75-unit loan would be about 0.92x. The equity test still says 20 units of cash. The rent test says the building can’t carry that loan. The loan has to shrink, or you look at a select-lender path for sub-1.00 coverage, where leverage and terms adjust. Either way, cash falls below the equity number.
What If the Appraisal Comes in Low?
A small miss in value hits cash harder than its size suggests, because the payoff is fixed. Use the same fourplex.
| Scenario | Value | Max loan (75%) | Net cash |
|---|---|---|---|
| Base case | 100 units | 75 units | 20 units |
| Appraisal 6% low | 94 units | 70.5 units | 15.5 units |
| Appraisal 12% low | 88 units | 66 units | 11 units |
A 6% miss in value cuts cash by about 22%. A 12% miss cuts it by 45%. Rent works the same way in reverse. If the appraiser’s market rent comes in under your leases, or a unit is vacant and the lender credits it at zero, coverage drops and the rent test can take over.
This is why you should run the math three ways before you commit: base, low appraisal, low rent.
Step 6: Check What the Bigger Loan Does to Your Monthly Picture
Go back to the coverage numbers above. The same building went from about 1.45x to about 1.09x because you added debt. Same rents, same taxes, much thinner cushion.
And here is the part that trips people up: clearing 1.00 is not positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses all sit outside it. A building at 1.09x on paper can still lose money once a roof and two turnovers hit. Treat coverage as a qualifying test, not a profit measure.
Where the General Rule Breaks
The two-test framework holds up in most files. These are the places it bends.
- Interest-only periods. An interest-only structure raises coverage today and raises the payment later. Some programs review the file on interest, taxes, insurance, and dues only. Extended terms (40-year) and interest-only periods are available through select lenders in the network.
- Free-and-clear buildings. Any new loan on a property with no mortgage is still a cash-out. The cash-out ceiling applies.
- Short-term rentals. Cash-out leverage on short-term-rental collateral caps at 70%, against 75% on a standard rental. Expect a 640+ score and about 12 months of hosting history. 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.
- Delayed financing. Some programs let an all-cash buyer pull money out sooner than the usual seasoning period. Details vary by program, so ask before you assume it.
- Large loans. Reserves commonly run about 6 months of PITIA and step up to about 9 months on loans above $1,500,000. Above $2,500,000, the network generally holds to 30-year fixed structures. Standard programs go up to $3,000,000.
- Credit. A 620 floor exists in parts of the network. Most programs want around 660. A score of 700 or higher unlocks the strongest leverage tiers.
- Entity-held property. LLC-held buildings require entity documents, subject to lender program eligibility.
- Property types. Manufactured homes, log homes, and barndominiums are not offered through these programs.
A bigger down payment or more equity helps. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rent coverage. Lendmire’s piece Is a Cash-Out Refinance Harder on a 2–4 Unit Rental goes deeper on that gap.
Is the Cash Worth What It Costs?
Standard refinance break-even math doesn’t fit here. That formula divides costs by monthly savings. A cash-out usually raises your payment, so there are no savings to divide by.
Judge the cash a different way. Add up the yearly cost of the extra debt plus your closing costs spread over the years you’ll hold. Divide by the cash you receive. That is the hurdle your reinvested money has to beat. Interest starts accruing on the full proceeds immediately, whether or not you’ve put them to work.
If you plan to use the cash as a down payment on the next rental, that purchase starts its own seasoning clock. Plan the sequence, not just the single deal.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
A quick go, trim, or wait checklist:
1. Go if both tests clear with cushion in all three scenarios and the cash has a defined use.
2. Trim if coverage lands near the floor. Pull less and keep a margin.
3. Wait if you’re inside the seasoning window, the appraisal looks soft, or rents are below market on expiring leases.

Frequently Asked Questions
Can I cash-out refinance a duplex, triplex, or fourplex on a DSCR loan?
Yes, 2-4 unit buildings are eligible property types across most of the network. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Cash-out leverage on an investment property tops out around 75% LTV, and about 6 months of seasoning is the common expectation.
How do I figure out how much cash I’ll actually get?
Multiply appraised value by the LTV cap, then subtract your payoff, closing costs, prepaid items, and any prepayment charge on the old loan. Then confirm the resulting loan still clears the coverage test. If rent is thin, the coverage test shrinks the loan and the cash with it.
Does 75% LTV mean I can take out 75% of my equity?
No. The cap applies to the entire new loan against the appraised value. Your payoff comes out of that 75% first, and the remainder is your cash before costs. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Which rent does the lender use on a 2-4 unit?
It varies by program. Many use the lower of signed leases and the appraiser’s market rent. Vacant units are treated differently by different lenders, so ask whether an empty unit is credited at market rent or at zero.
If my coverage clears 1.00, am I cash-flowing?
Not necessarily. Coverage compares rent to PITIA only, and it ignores repairs, vacancy, management, utilities, and capital expenses. Clearing the ratio means you meet a qualifying test, not that you profit each month.
