The Quick Read: What you keep is 75% of the appraised value, minus your current payoff, minus closing costs, minus the cash you must hold back as reserves. That check is smaller than most owners expect, because a duplex, triplex, or fourplex gets a lower leverage cap than a single-family home. Rent from your other units helps you qualify, but only partly. Run the math in that order and you will know what the next purchase can really use.
Key Takeaways
- A cash-out refinance on a 2–4 unit home you live in is capped at 75% of value. A one-unit home is capped at 80%.
- At least 25% of the building’s value stays as equity. That is the permanent cost of the strategy.
- Closing costs come off the top, either from your proceeds or by enlarging the loan.
- Reserves are separate. Cash you take out does not double as the reserves the lender wants to see.
- Rent from the unit you occupy does not count toward qualifying. Rent from the other units counts, with a haircut.
- A streamline refinance is not a cash tool. It lowers a payment on an existing government loan.
What a 2–4 Unit Cash-Out Refinance Actually Does
A cash-out refinance replaces your current first mortgage with a larger one. The new loan pays off the old balance and the closing costs. You get the rest as cash. You can spend it on anything, including a down payment on your next property.
Cash-out refinance estimate
The starting figures are an example value with a balance and a cash request in proportion. Replace them with yours.
Editable benchmark: 7.40% as of October 15, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a cash-out refinance quote.
Illustrative starting assumptions: a $350,000 home value, a $193,000 current balance, the agency cap on a one-unit principal residence, a thirty-year term at the current Freddie Mac benchmark, and property taxes and insurance estimated at typical national rates. Every field is editable.
Illustrative estimate only — not a Loan Estimate, approval, quote, or commitment to lend. The rate field carries the weekly Freddie Mac thirty-year conventional benchmark, a market reference and not a cash-out refinance quote; a cash-out loan is priced by the lender at lock. The cash available is the loan the program cap allows less the balances paid off, before closing costs, which are not included. The HELOC line is the program’s combined loan-to-value ceiling applied to the same value and balance. Taxes and insurance are editable estimates. Licensed in sixteen states for consumer mortgages.
You must live in one of the units for this to be an owner-occupied loan. That one fact drives the leverage, the pricing tier, and the qualifying rules. Lendmire’s cash-out refinance programs are built on that owner-occupied footing. Lendmire is a mortgage broker licensed for consumer lending in 16 states, and it arranges these loans through wholesale lenders. Every figure below is subject to lender guidelines and a full file review. None of it is a commitment to lend.
Here is the practitioner’s view. Most owners of a small multifamily ask the wrong question first. They ask how much equity they have. The better question is how much of that equity the loan can reach after the cap, the payoff, the costs, and the reserves. Equity is the ceiling. The check is what’s left after four deductions.
Key Terms Defined
Cash-out refinance: A new, larger mortgage that pays off your old one and hands you the difference in cash.
Loan-to-value (LTV): The loan balance divided by the property’s appraised value. A 75% LTV means the loan is three-quarters of what the home appraises for. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Rate-and-term (limited cash-out) refinance: A refinance that pays off the old loan and costs, with only incidental cash back. It is not a way to pull spendable equity.
Reserves: Money you still hold after closing, such as savings and investment accounts, that could cover several months of housing payments.
Debt-to-income ratio (DTI): Your total monthly debts divided by your monthly income. Lenders use it to judge whether you can carry the new payment.
Seasoning: The waiting period a lender requires before you can refinance or pull cash. It is measured from the date of the existing loan or from when you took title.
Delayed financing: An exception that lets you take cash out soon after buying a property with cash.
The Formula, Step by Step
The formula has five lines.
1. Appraised value times the leverage cap gives you the maximum new loan.
2. Subtract the payoff on your current first mortgage.
3. Subtract any other liens that must be paid off.
4. Subtract closing costs and prepaid items.
5. That is your gross check. Now subtract what you need to keep in reserves to learn what you can deploy.
Think of it as gross cash versus deployable cash. Gross cash is what the closing table hands you. Deployable cash is what you can spend without leaving either building thin.
A quick picture. Say the building appraises at 100 units of value and your payoff is 50% of that. At a 75% cap, the new loan is 75 units. Take away the 50-unit payoff and you have a 25-unit gross check, before costs. At an 80% cap on a one-unit home with the same payoff, that figure would be 30. The duplex owner gives up five points of value to the cap.
Costs vary by borrower and lender. Expect the usual items: origination charges, an appraisal, title insurance, and taxes and fees. Your Loan Estimate shows the total closing costs on each offer, because the Loan Estimate rule requires the form to disclose them. Compare offers on net cash after costs, not on the headline loan amount.
Why a Duplex Gets a Smaller Check Than a House
The agencies treat two to four units as a higher-risk property. So the cap drops. The Fannie Mae Eligibility Matrix sets the maximum LTV for a principal-residence cash-out refinance at 80% for one unit and 75% for two to four units. Across the wholesale programs Lendmire places files with, the same split holds on the conventional lanes.
Here is the same building on an indexed value of 100, with a payoff of 50% of value. These are modeled assumptions, not market data.
| Property type | Leverage cap | Gross cash before costs |
|---|---|---|
| One unit | 80% | 30 |
| Duplex | 75% | 25 |
| Triplex | 75% | 25 |
| Fourplex | 75% | 25 |
Notice the last three rows are identical. Adding a unit does not raise the cap. It changes the appraisal form, the rent analysis, and the reserve rules. It does not change the percentage.
Occupancy changes the answer too. Occupancy sets leverage, so a building you do not live in follows a different set of limits than the one described here. If you plan to move out and rent every unit, you are no longer in the owner-occupied lane.
Two Tests That Size Your Check
Your check has to pass two tests. The equity test sets the ceiling. The qualifying test can lower it.
The equity test. This is the formula above. The cap leaves you with at least 25% equity in the building. That remaining equity is your cushion. It is also the base for any later credit line or sale.
The qualifying test. A bigger loan means a bigger payment. The lender counts that whole payment in your debt-to-income ratio. For most files, the automated finding governs, with a total ratio ceiling of 50%. Manually underwritten loans run tighter, at 36% or 45%, depending on score and reserves.
Here is where the rent comes in. Freddie Mac’s 2- to 4-unit guidance allows rental income from the other units to be added to your income. Cash-out refinance is an eligible transaction. The same page sets a 45% maximum DTI for manually underwritten loans. Two details trip people up:
- Rent from the unit you live in generally cannot be used to qualify.
- Rent from the other units is reduced for vacancy and expenses. You do not get credit for the full lease amount.
So the rent helps, but it does not erase the payment. A common surprise is a borrower with plenty of equity and a DTI that stops the loan before the cap does. In that case, the rent test sizes your check. Equity does not.
Worked Example: From Refinance to Next Closing
Run the numbers on a hypothetical owner of a duplex. All figures below are modeled assumptions, expressed as shares of the building’s appraised value.
- Appraised value: 100 units.
- Current payoff: 50% of value, so 50 units.
- Cap: 75%, so the maximum new loan is 75 units.
- Gross cash before costs: 25 units.
- Closing costs and prepaid items: these come out of the 25. Your Loan Estimate shows the real number, so the net check lands somewhat below 25.
Now the next purchase. Say the owner wants a home priced at 60% of the first building’s value, and plans to occupy it as a principal residence. Program limits allow up to 95% LTV on a two- to four-unit principal residence purchase, so the down payment is as little as 5%. On a 60-unit purchase, that is 3 units. Closing costs on the new purchase come on top. A second home carries a lower cap, at 90% LTV, so the down payment is larger. Anything that is not a home you will occupy needs more again. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
The check clears the down payment with room to spare. But here is the catch. Under the Fannie Mae reserve rules, cash back from a refinance is subtracted from the reserves you can count. The check does not pay double duty as your cushion. A two- to four-unit principal residence also carries a reserve requirement of its own. So the surplus after the down payment is not free cash. It is partly the money you need to keep in the bank for both buildings. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
That is the honest answer to the title. The refinance leaves you less than the gross figure and often less than you hoped. It works when the next deal’s down payment, costs, and reserves fit inside the net check, with something left over.
Sensitivity: What an Appraisal Does to the Check
The appraisal is the lever owners underestimate. Because the payoff is fixed, a small change in value moves your cash by a much larger percentage. Same duplex, same payoff of 50 units, same 75% cap:
| Appraised value | Maximum loan | Gross cash before costs |
|---|---|---|
| 95 (down 5%) | 71.25 | 21.25 |
| 100 | 75 | 25 |
| 105 (up 5%) | 78.75 | 28.75 |
A 5% miss on value cuts gross cash by 15%. The leverage works in both directions. On a two- to four-unit property, the appraiser uses a small residential income property form, which supports market rent as well as comparable sales. So a thin comp set or a rent schedule that looks soft can pull the number down.
What Quietly Shrinks the Check
A few items never show up in the headline formula. Check each one before you plan around a figure.
- Other liens. A second mortgage or credit line on the building has to be paid off in the refinance. That comes out of your cash. Paying off a non-purchase second lien on a limited cash-out refinance also converts it to a full cash-out refinance.
- Prepaids and escrows. Taxes and insurance get funded at closing for the escrow account. That is your money, but it is not in your hands.
- Mortgage insurance. At 75% LTV you are below the 80% line where mortgage insurance applies on a conventional loan. That is one cost this structure avoids.
- Costs rolled into the loan. If you finance the costs, the loan grows and your payment grows with it. That also pushes your DTI up.
- A holdback. Some files carry a condition, such as a repair, that ties up funds until it is complete. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Timing: Seasoning and Delayed Financing
You cannot always pull cash right after buying. On the conventional cash-out lanes Lendmire places, the first mortgage being paid off must be at least 12 months old, measured note date to note date. A borrower must also have been on title for six months. Exceptions exist for delayed financing, inheritance, and legal awards.
Delayed financing is the one that matters if you bought the building with cash. Fannie Mae’s cash-out policy requires that the original purchase was an arm’s-length transaction. A property listed for sale must be taken off the market on or before the new loan’s disbursement date. Plan around that, because a listed building does not qualify.
Where the Rule Breaks
Every rule above has exceptions. These are the ones I see most.
Limited cash-out is not cash-out. A rate-and-term refinance on a 2–4 unit home allows a much higher LTV than a cash-out. But the cash back is only incidental. It pays off the old loan and costs. It is not a source of spendable equity, so do not confuse the higher number with a bigger check.
Streamlines pay out little or nothing. The FHA Streamline refinances an existing FHA loan with limited credit review. It must produce a net tangible benefit, and HUD says closing costs cannot be rolled into the new amount. The VA IRRRL does the same for an existing VA loan. Both lower a payment. Neither funds a purchase.
Government cash-out has its own lanes. FHA and VA each offer cash-out refinancing on a primary residence. Their limits differ from conventional, and lenders often add their own caps. They suit borrowers whose loan is already government-backed, but the unit-count rules and appraisal requirements still apply.
Counting your properties. Your new mortgage counts toward the number of financed properties on your record. Agency rules place no cap on financed properties for a principal-residence purchase. A second home or other non-owner-occupied purchase triggers added reserves. A two-unit counts as one property.
Moving out. If you leave and rent every unit, the occupancy requirement fails. A different loan lane applies, with different leverage.
Tax. Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
Go or Wait? A Checklist
Run these questions before you apply. If you answer no to two or more, wait.
- Does the net check, after costs, cover the next deal’s down payment, closing costs, and reserves?
- Can you still show reserves on both properties that do not depend on the cash-out proceeds?
- After the new loan, does your DTI sit comfortably under the ceiling, counting only the rent the lender will credit?
- Does the building keep at least 25% equity?
- Would the building still carry its payment if one unit sat vacant for a stretch?
- Have you met the seasoning rule, or does an exception apply?
The last test is the one people skip. A refinance that squeezes your cash flow on the building you already own can make the second purchase harder to qualify for, not easier. This is a genuine toss-up for borrowers with thin margins. The cash is real, but so is the larger payment.

Frequently Asked Questions
Can the cash-out proceeds be my down payment on the next purchase?
Yes, in most cases. Cash from a refinance is yours to spend. The catch is reserves: cash back is deducted from the reserves a lender will count, so you generally need other funds in the bank. Subject to lender guidelines and full file review.
Does a duplex release more cash than a single-family home?
Not at the same value and payoff. A one-unit principal residence is capped at 80% on conventional cash-out. A two- to four-unit is capped at 75%. A duplex may have more equity in dollars if it is worth more, but the cap leaves a smaller share of each dollar of value.
What if one unit is vacant?
Vacancy hurts the qualifying test, not the equity test. Rent from the other units is counted with a haircut, and a vacant unit may leave you with less countable income. Appraisers also report market rent for each unit. Some lenders want the unit leased before they count the income.
Can I chain refinances to keep pulling cash?
Each pull is limited by the 75% cap, so the second pull has less room. You must also meet seasoning again, because the existing first mortgage has to be at least 12 months old. Every pull erodes your equity cushion and raises the payment.
Do I have to live in the building?
Yes, for owner-occupied loans. You must live in one of the units. Occupancy decides the leverage, so a building you do not occupy follows a different set of limits.
