The Quick Read: The cash you can free is set by a loan-to-value limit, not by the equity you own on paper. On a one-unit primary residence, a conventional cash-out loan tops out at 80% of the home’s appraised value. The new loan must cover the old payoff, the other owner’s share, and the closing costs. Sometimes a buyout can be handled as a limited cash-out refinance, which allows more leverage. Subject to lender guidelines and full file review, the loan-to-value limit, not the paper equity, decides whether the buyout works.
What “Buyout” and “Scaling” Mean Here
A buyout means one owner pays another owner out of a shared home. It comes up in divorces, in co-ownership between siblings or partners, and in inherited homes. The person staying signs a new mortgage. That mortgage pays off the old loan and sends the leftover cash to the person leaving.
“Scaling” has no rule or definition in any lender guideline. Here it means something plain: growing your own balance sheet. You end up as sole owner, on a loan you carry alone, with a plan for what comes next. That might be a move-up, a renovation, or simply stable footing. Every program covered below is for a home you live in.
This article walks through the mechanics, the formula, two worked examples, and the places where the usual rule breaks. Lendmire’s cash-out refinance programs fit inside the same envelope described here. Lendmire is a broker, so lenders make the actual credit decisions.
Paper Equity vs. Reachable Equity
Paper equity is what the home is worth minus what you owe. Reachable equity is smaller. The lender will not lend you every dollar of value, so some equity has to stay in the house.
Here is the formula for what a cash-out loan can release:
- Cash released = (appraised value × maximum LTV) − payoff of existing liens − closing costs.
LTV is loan-to-value: the loan balance divided by the home’s appraised value. A cap of 80% means the new loan cannot exceed 80% of that value. The Fannie Mae Eligibility Matrix sets 80% for a cash-out loan on a one-unit principal residence and 75% on two- to four-unit homes. Across the wholesale programs Lendmire places files with, the numbers line up with that.
Now flip it around. The buyout formula asks what the new loan has to cover:
- New loan needed = existing payoff + the other owner’s share + closing costs.
The deal works when the new loan needed is at or below the cap. That is the whole game. Everything else here is about which inputs move those two numbers.
Entitlement vs. Capacity
Two different forces set the size of your buyout check. One is what you owe. The other is what the lender will lend.
| Question | Who sets it | What drives it |
|---|---|---|
| What does the other owner get? | You and the other owner | Ownership split, agreement, decree |
| What can the lender release? | The loan program | Appraised value, LTV cap, payoff |
| Can you carry the loan alone? | The underwriter | Income, credit, debts |
A fair settlement can still be out of reach if capacity is smaller than entitlement. Most buyouts that stall do so on that gap. Plan for it early.
Worked Example 1: The Check Covers the Share
Use percentages of the home’s value so the math stays clean. These are modeled assumptions, not market data.
- Appraised value: 100%.
- Existing mortgage payoff: 50%.
- Equity on paper: 50%.
- Ownership: 50/50, so the other owner is owed 25%.
- Loan needed: 50% + 25% = 75%, plus closing costs.
The cap on a one-unit primary residence cash-out is 80%. That leaves about five percentage points of room. Closing costs eat into that room. The buyout works, with a thin cushion.
Now suppose the appraisal comes in 10% lower than the number you both expected. The cap becomes 80% of 90%, which is 72% of the expected value. The loan needed is still 75%. A cushion becomes a shortfall because of one appraisal. That is why the appraisal matters so much.
Worked Example 2: The Check Falls Short
- Appraised value: 100%.
- Existing mortgage payoff: 65%.
- Equity on paper: 35%.
- Ownership: 50/50, so the other owner is owed 17.5%.
- Loan needed: 65% + 17.5% = 82.5%, plus closing costs.
The cap is 80%. The gap is 2.5% of the value, before costs. Three common ways to close it:
1. Renegotiate the price. Offer a smaller payout, or split the shortfall.
2. Add your own cash. Savings or a gift can fill the gap.
3. Pay in two parts. The refinance funds most of the buyout. The rest is paid by a written installment agreement. Both owners need to be comfortable with that note.
Some people also look at a home equity loan or line of credit on top of the new first mortgage. Those add a second payment and are underwritten separately. Lendmire’s separate piece How Much Equity a Cash-Out Refinance Frees When You Keep a Low First covers that tradeoff.
When a Buyout Can Use Higher Leverage
This is the structure that surprises people. Fannie Mae can treat a qualifying buyout as a limited cash-out refinance. A limited cash-out refinance is a rate-and-term loan with only incidental cash back. It pays off the existing first mortgage, closing costs, and a purchase-money second lien. In the wholesale programs I place files with, it reaches 95% LTV on a one-unit principal residence. It can reach 97% where the existing loan is agency-owned and the first-time-buyer program allows. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Fannie Mae’s limited cash-out guidance includes a section titled “Refinances to Buy Out An Owner’s Interest.” The buyout must come from a real event, such as a divorce settlement or the end of a domestic partnership. The owners generally have to have held the property together for a qualifying period. Check the live guide for the exact period before you plan around it.
Go back to Example 2. Loan needed was 82.5%. Under the 95% limited cash-out cap, that fits with room to spare. The tradeoff is mortgage insurance. It is required above 80% LTV. You can ask to cancel it at 80% of the original value, with a good payment history, no subordinate liens, and no decline in value. The servicer must terminate it automatically at 78%. Published typical annual premiums run 0.58% to 1.86% of the balance. That is a range, not a quote. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Freddie Mac handles the same situation differently. Its special-purpose cash-out refinance is built for buying out a co-owner. It must meet the regular cash-out rules except where that section changes them. The proceeds go to the buyout, payoffs, and costs. The usual twelve-month age requirement on the existing first loan does not apply to this type. Because it follows cash-out rules, leverage is lower than on a limited cash-out. Which path your file takes depends on the lender and the investor behind it.
What Shrinks the Check
Five things move your number. Know which way each one pushes.
| Input | Effect on cash released |
|---|---|
| Lower appraisal | Cuts it, because the LTV cap shrinks |
| Larger existing payoff | Cuts it, dollar for dollar |
| Closing costs and prepaids | Cut it, unless you pay them separately |
| Junior liens to be paid off | Cut it, and may change the loan type |
| Higher appraisal | Raises it |
Two edge cases deserve a flag. Paying off a second lien that was not used to buy the home can turn a limited cash-out loan into a regular cash-out loan. That drops your maximum LTV. A home that was recently listed for sale may also need to come off the market first for limited cash-out treatment. Confirm both with the lender before you sign a buyout agreement.
Seasoning, Title, and Paperwork
Seasoning is the waiting period before a loan or ownership can be used in a new refinance. Conventional cash-out rules set two clocks. The first mortgage being paid off must be at least 12 months old, counted note date to note date. At least one borrower must have been on title for six months. Freddie Mac’s cash-out section lays out both clocks, and Fannie Mae’s cash-out guide covers the loan-age rule and a delayed financing exception. Delayed financing helps someone who bought the home with cash and wants equity out soon after. Exceptions also exist for inheritance and legal awards.
Because a buyout is a legal exit, the lender will want proof. Expect a divorce decree, a settlement, or a signed co-ownership agreement that defines each person’s share. Draft it so the price follows the appraisal. A clause that says “half of the appraised equity” is safer than a fixed number. A fixed number can break the moment the appraisal comes in low.
Here is something many people miss. A divorce decree does not take someone off the existing mortgage. The lender’s contract stays in place. Only a payoff or a refinance ends it.
Can You Qualify Alone?
The lender approves you, not the old household. After the buyout, your income has to carry the new loan by itself. Across the wholesale conventional programs I place files with, the typical floor is a 620 decision score. The automated underwriting finding governs most files, with a total debt ratio ceiling of 50%. Manually underwritten loans use 36% or 45%, with reserve and score factors. Subject to lender guidelines and full file review, these are the numbers to test yourself against.
A debt ratio is your monthly debts, including the new mortgage, divided by your gross monthly income. Dropping the other owner’s income can push that number up fast. Run it before you commit to a price.
If your credit has had a recent hit, agency waiting periods apply. These are four years from a chapter 7 discharge, seven from a foreclosure, and four from a short sale or deed-in-lieu. They are shorter with documented extenuating circumstances. They are the agencies’ rules, not the lender’s preference.
The Lane Without Mortgage Insurance
There is a wholesale cash-out lane that reaches 89.99% LTV with no mortgage insurance. It requires a 680 score, a 50% ratio, a thirty-year fixed rate, a primary residence, and a conforming balance. It carries its own six months of seasoning. Whether a buyout file fits is a lender call. In Texas, a cash-out on the homestead is capped by the state constitution at the agency figure, and this lane is not written there. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
When the Usual Rule Breaks
- Occupancy changes the cap. A second home or a rental gets lower leverage than your primary residence. Occupancy decides the number.
- Government streamlines cannot fund a buyout. The FHA Streamline and the VA IRRRL are built to refinance an existing government loan without much underwriting. Neither is designed to pull out equity, so neither pays another owner. FHA and VA each have their own full cash-out loans for homes you occupy. Lenders set their own caps on those.
- Jumbo loans. Above the conforming limit, a jumbo lane takes over, with a 660 decision score and leverage to 90%.
- Multi-owner exits. When one of several owners leaves, the math is the same, but every remaining owner has to qualify and sign.
Does the Larger Loan Leave Room to Scale?
Be honest about the price of the buyout. The CFPB’s guide on using home equity says a cash-out refinance replaces your mortgage with a larger one. The new terms apply to the whole balance, the payment may go up, and the payoff can stretch out. It also says no product turns all your equity into cash.
For scaling, three questions matter after closing:
1. How much equity is left? The LTV cap guarantees some stays in the home, which is useful cushion.
2. How tight is your debt ratio? A buyout that leaves you near the ceiling limits what you can borrow next.
3. How much cash do you hold? Reserves help a file and cushion the first year alone.
A smaller buyout, even if it means renegotiating, can leave you better placed than one that uses every point of leverage.
Steps From Agreement to Closing
1. Get an informal value estimate and a payoff statement for every lien.
2. Agree on the split and write it down, with an appraisal-linked price clause.
3. Run the formula both ways: cash released and loan needed.
4. Decide on the loan type, whether limited cash-out, cash-out, or a government option.
5. Apply, order the appraisal, and document income, assets, and credit.
6. Review the Loan Estimate and compare full terms across offers.
7. Close, with the old liens paid off and the buyout funds going to the departing owner.
Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
When a Cash-Out Refinance Is the Wrong Tool
Skip it if the new loan would be larger than you can carry, or if the existing loan is a very good one you would be giving up. Alternatives include paying in installments, using savings or a gift, selling the home and splitting the proceeds, or buying out only part of the other owner’s share now. Each has a cost. None is wrong in every case.
Key Terms Defined
Loan-to-value (LTV): The loan balance divided by the home’s appraised value.
Cash-out refinance: A new, larger mortgage that pays off the old one and puts the extra cash in your hands.
Limited cash-out refinance: A refinance that pays off the old loan and costs, with only incidental cash back.
Seasoning: The required age of a loan or time on title before it can be used in a refinance.
Paper equity vs. reachable equity: Paper equity is value minus debt. Reachable equity is what the LTV cap lets you borrow.
Debt ratio: Monthly debts divided by gross monthly income.
Frequently Asked Questions
Can I take out all my equity to buy out my co-owner?
No. The LTV cap leaves some equity in the home. Conventional cash-out on a one-unit primary residence stops at 80%. A qualifying buyout can sometimes be written as a limited cash-out loan with higher leverage.
Does the other owner have to be on the new loan?
No. The point of a buyout is that the departing owner comes off the loan and the title. You must qualify alone, and the departing owner signs documents that transfer their interest.
What if the appraisal is lower than we thought?
The cap shrinks with it, and your cash drops. That is why the price clause should track the appraisal. If the gap opens up, the options are a lower price, extra cash from you, or an installment payment for the rest.
Can an FHA Streamline or VA IRRRL pay out my ex?
No. Both are built to refinance an existing government loan, not to pull out equity. A full FHA or VA cash-out loan on a home you occupy is the route there.
Will closing costs come out of the money for the buyout?
Costs may be rolled into the new loan, which uses up room under the cap, or paid separately. Either way, they reduce what reaches the other owner unless you cover them.
