The Quick Read: A conventional refinance can pay a co-owning sibling for their share of a home you plan to keep. Fannie Mae treats a buyout of a co-owner under a written agreement as a limited cash-out refinance, and Freddie Mac treats it as a special purpose cash-out refinance. Either way, you must qualify on your own income and credit, and the new loan pays off the old mortgage and the departing sibling together.
Key Takeaways
- The new loan replaces your current mortgage, pays your sibling their equity share, and covers allowed closing costs.
- Fannie Mae classifies a qualifying buyout as limited cash-out, which usually allows more leverage than a standard cash-out. Freddie Mac applies its cash-out limits.
- The 12-month loan-age rule on the mortgage being paid off has a co-owner buyout exception at Fannie Mae.
- You qualify alone. Your sibling’s income does not count, and a deed transfer alone does not release them from the old loan.
What Is a Sibling Buyout Refinance?
A sibling buyout refinance is a new mortgage that lets one co-owner keep a home by paying the other co-owners for their equity. It usually comes up after an inheritance, but it works for any co-owners who agree on a price. The new loan pays off the existing first mortgage. It then funds your sibling’s share, plus allowed costs.

Lendmire’s cash-out refinance programs page covers the broader loan type. The buyout is a specific use of it, and that use gets special treatment from the agencies.
The agencies are Fannie Mae and Freddie Mac, the two entities that set most conventional underwriting rules. Fannie Mae’s Selling Guide section B2-1.3-02 says a transaction requiring one owner to buy out another owner’s interest is a limited cash-out refinance when the property was jointly owned for at least 12 months before the new loan’s disbursement date. The same section lists buying out a co-owner under an agreement among the permitted uses of limited cash-out proceeds.
The Guide language says “co-owner,” not “spouse.” Siblings who share title fit the same wording.
How Is the Loan Underwritten, Step by Step?
Underwriting follows six steps: confirm title, document the agreement, appraise, qualify the keeper alone, size the loan, and close. Each step has its own purpose, and the sections below walk through them in order.
1. Confirm who is on title and for how long. Co-owners generally should have held title jointly for at least 12 months before disbursement. Inherited interests carry their own exceptions, covered below. Freddie Mac also asks for evidence that the borrower and the departing co-owner occupied the home as a primary residence, with an exemption for people who inherited their interest.
2. Put the agreement in writing. The Guide ties the buyout to a co-owner agreement. In practice, that means a signed buyout or settlement agreement stating the price and the terms. Everyone with an ownership interest should sign it.
3. Let the appraisal set the number. Siblings often disagree about what a house is worth. The lender’s appraisal gives a neutral value that drives both your sibling’s share and the maximum loan.
4. Qualify the keeper alone. Your income, credit, assets, and debt ratios must work without your sibling. The wholesale conventional programs start at a 620 decision score. The automated finding governs most files, with a total ratio ceiling of 50%. Everything is subject to lender guidelines and a full file review.
5. Size the loan. The amount is the payoff of the existing first mortgage, plus your sibling’s equity share, plus allowed closing costs. All of it has to fit under the leverage cap for your occupancy and unit count.
6. Close and record. The title or settlement agent pays your sibling from the loan proceeds and records the deed or release. Your sibling signs the agreement and the deed. They do not need to be a borrower on the new loan.
How Much Can You Borrow?
For a one-unit principal residence, a buyout that qualifies as limited cash-out can reach 95% loan-to-value, or 97% where the existing loan is agency-owned and the first-time-buyer program allows. A standard cash-out on the same home is capped at 80%, and at 75% on two- to four-unit homes. Those are the guideline figures across the wholesale programs Lendmire arranges loans through, and they depend on the specific file.
Fannie Mae’s eligibility matrix lists leverage tiers by occupancy and transaction type, and those tiers change over time. Check current figures with a loan officer before you plan around any one number.
Here is why the classification matters. Say a house is appraised and your sibling’s share is half of the equity. Under the limited cash-out tier, the loan can carry more of the home’s value than it could under standard cash-out. That can be the difference between a buyout that works and one that leaves you short of cash.
Freddie Mac applies its cash-out loan-to-value limits to special purpose buyouts under its Guide section 4301.6. Two agencies can produce different maximum loans on identical facts. A broker can check which path your file fits.
On the agency path, mortgage insurance is required above 80% LTV, with one exception: the wholesale no-MI cash-out lane, which reaches 89.99% LTV at a 680 score on a thirty-year fixed, primary residence with a conforming balance. That lane is a separate cash-out option with its own seasoning, so a buyout is not automatically eligible for it. Where insurance applies, it can be canceled at your request at 80% of the original value, with good payment history, no subordinate liens, and no decline in value. The servicer must end it automatically at 78%. Lendmire’s conventional program sheet lists typical annual premiums of 0.58% to 1.86% of the balance. That is the program sheet’s range, not a quote.
Does the 12-Month Rule Apply to Buyouts?
It depends on the agency, and Fannie Mae’s rules are the ones confirmed here. A standard cash-out requires that the first mortgage being paid off be at least 12 months old, measured note date to note date. Fannie Mae’s cash-out refinance rules say that requirement does not apply when buying out a co-owner under a legal agreement.
Without that exception, someone who refinanced the family home a few months ago would have to wait. With it, the buyout can proceed under Fannie Mae’s rules. Freddie Mac handles seasoning differently, so confirm which agency’s rules apply to your file.
A standard cash-out also generally requires that you have been on title for 6 months, with exceptions for delayed financing, inheritance, and legal awards.
Where Does the General Rule Break?
Several situations change the path. Each one is worth raising with a broker before you sign anything.
Inherited homes. Inheritance waives the title-age wait, but not every waiting period. The loan-age rule is a separate test. If a mortgage is being paid off, the co-owner buyout exception is the cleaner route.
Under 12 months of joint ownership, or one name on title. The limited cash-out buyout may not apply as written. The loan can fall to standard cash-out treatment, with the lower leverage cap.
A home with no mortgage. A new first mortgage on a free-and-clear home is treated as cash-out. A buyout on an unencumbered inherited home is a different path from a payoff refinance, so ask the lender how it will be classified.
Taking extra cash for yourself. The proceeds are meant for the departing co-owner. Only a small incidental amount of cash back is allowed on a limited cash-out. Fannie Mae’s cap is the lesser of 2% of the new loan amount or $2,000, and Freddie Mac’s is the greater of 1% of the new loan amount or $2,000. Take more and the loan is reclassified as standard cash-out.
A non-occupant co-signer. Rules for adding a parent or other co-borrower differ between agencies and between occupancy types. Confirm before assuming a relative can co-sign.
Non-agency loans. Jumbo loans sit outside agency rules, so the limited cash-out reclassification is not a given. Above the conforming limit, the jumbo lanes take over, with a 660 decision score, leverage to 90%, loans to $5,000,000, and a 50% ratio ceiling on the fixed lanes.
Texas homesteads. A cash-out on a Texas homestead is capped at 80% of the home’s value by the state constitution. The wholesale no-MI lane is not written there.
Renovation add-ons. Buying out a co-owner is a limited cash-out transaction at Fannie Mae and a special purpose cash-out refinance at Freddie Mac, and it is not a HomeStyle Renovation feature.
Is There a No-Mortgage-Insurance Option?
Sometimes. One wholesale lane reaches 89.99% LTV with no mortgage insurance. It requires a 680 score and a 50% ratio on a thirty-year fixed, a primary residence, and a conforming balance. It also carries its own six months of seasoning. Because of that seasoning, it fits fewer buyouts than the standard agency path does. It is the one exception to the 80% mortgage-insurance rule, and eligibility depends on the lender’s guidelines and your full file.
Key Terms Defined
Limited cash-out refinance: A refinance that pays off the current first mortgage and closing costs, with only a small amount of cash back.
Special purpose cash-out refinance: Freddie Mac’s name for a cash-out loan whose proceeds buy out a co-owner’s equity.
Seasoning: The minimum time a mortgage or ownership interest must exist before a new loan can replace or use it.
Loan-to-value (LTV): The loan amount divided by the home’s appraised value, shown as a percentage.
Decision score: The credit score a lender uses to review the file. The wholesale conventional programs start at 620.
What Does It Cost You, and How Does It Change Your Budget?
The new loan is larger than the old one, so the monthly obligation usually goes up. The Consumer Financial Protection Bureau notes that a cash-out refinance may extend the time it takes to pay off the mortgage, and the monthly payment may increase because a larger loan replaces the current one. You also give up your existing loan terms when it is paid off, which matters if your current loan is a good one.
Closing costs generally apply as well. The same agency notes that borrowers often pay closing costs on a cash-out refinance. As a consumer loan, it comes with a Loan Estimate and Closing Disclosure.
Qualifying on one income is usually the binding constraint. If your debt-to-income ratio is high, ask about reserves, because Fannie Mae requires six months of reserves on certain cash-out files with DTI above 45%.
Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
What Can Go Wrong?
Four problems commonly derail a buyout.
The appraisal comes in low. A lower value shrinks both the maximum loan and your sibling’s equity share. You can renegotiate the buyout figure, bring cash, or wait. Agreeing in advance on how a low value will be handled saves a lot of friction.
Siblings disagree on value. The appraisal is a neutral number, but a sibling who rejects it can stall the whole plan. Settle the valuation method in the written agreement before ordering anything.
A lien or second mortgage surfaces. Equity is value minus every lien. Pull the title report early and subtract all liens before anyone negotiates a number. A purchase-money second lien can be paid off in the new loan, but other liens complicate the file.
You can’t qualify alone. A buyout that looks fair on paper fails if your income can’t support the larger loan. Run your debt ratios first.
What Does the Departing Sibling Need to Know?
The sibling being bought out should know two things. Signing a quitclaim deed does not release them from the old mortgage. Only a payoff or a lender release does, and the refinance accomplishes that. They should also read the buyout agreement carefully before signing and confirm the payout amount on the settlement statement. Questions about taxes on their proceeds belong with a tax professional.
What Documents Should You Gather?
- The written buyout or settlement agreement, signed by all co-owners
- Proof of how and when each owner took title
- Your current mortgage statement and payoff information
- Income, asset, and credit documents for the keeping borrower
- For inherited homes, the documents showing how your interest passed to you
Frequently Asked Questions
Does the departing sibling have to sign the new loan?
No. They do need to sign the buyout agreement and the deed or release, and they are paid from the loan proceeds at settlement. You must qualify on your own.
Can I take extra cash out for myself in the same loan?
Only a small incidental amount. More than that typically changes the classification to a standard cash-out, which carries a lower leverage cap.
Does inheriting the home waive every waiting period?
No. Inheritance waives the title-age wait, but the 12-month loan-age rule on an existing mortgage is a separate test. The co-owner buyout exception is usually the cleaner route when a mortgage is being paid off.
Is the buyout treated the same by Fannie Mae and Freddie Mac?
No. Fannie Mae calls it limited cash-out, while Freddie Mac calls it special purpose cash-out and applies its cash-out leverage limits. Identical facts can produce different maximum loans, so the choice of agency path matters.
What if we have owned the home for less than 12 months?
The limited cash-out buyout may not apply as written, and the loan can fall to standard cash-out treatment. That means a lower leverage cap. Ask a broker to review your title history before you sign any agreement.
