To get bought out of a house you co-own, you and the other owner agree on the property’s value, calculate your share of the equity, sign a written buyout agreement, and transfer your interest by deed only after the remaining owner has refinanced the mortgage into their name alone. That last step is what separates a clean exit from a costly one. Signing away your ownership without getting off the loan leaves you responsible for a mortgage on a house you no longer own.
Agree on What the House Is Worth
The buyout starts with a number both of you can defend. A licensed appraiser inspects the property, reviews comparable sales, and produces a written opinion of market value. A standard single-family appraisal runs between $300 and $450 and carries weight if the buyout ends up in front of a judge, which matters in divorce and estate settlements.
A real estate agent’s comparative market analysis is the cheaper alternative, often free, but it lacks the precision and legal standing of a formal appraisal. When real money is changing hands, pay for the appraisal. If you cannot agree on a single appraiser, each of you can hire one and split the difference. That compromise heads off the argument that one side picked a friendly valuer.
Calculate Your Share of the Equity
Your buyout price is based on equity, not the sale price of the house. Equity is the current market value minus the remaining mortgage balance and any other debts secured by the property. If the home appraises at $400,000 and $200,000 is left on the mortgage, the equity is $200,000. A 50% owner is owed $100,000.
Ownership shares are not always even. The deed or a written co-ownership agreement may set different percentages tied to the down payment, mortgage payments, or renovation costs each person contributed. Without a written agreement, this is where negotiations get contentious. One co-owner may argue they paid alone for two years or funded a new roof. Settle those adjustments in writing before you agree on a final number, or the deal will unravel later.
Do Not Sign the Deed Until You Are Off the Mortgage
This is the mistake that costs people the most. A quitclaim deed gives up your ownership interest, but it does nothing to remove you from the mortgage. The mortgage is a separate contract with the lender, and the lender does not care what the deed says. If your name stays on the loan and the other co-owner stops paying, your credit takes the damage and the lender can pursue you for the balance.
The only ways to sever your mortgage obligation are for the remaining co-owner to refinance the loan in their own name, or for the lender to formally release you through a loan assumption agreement. Until one of those happens, keep your name on the deed. Insist that the refinance close simultaneously with or before you transfer your interest. Put a hard deadline in the buyout agreement. If the other co-owner cannot qualify, walking away from the deal is a reasonable response.
How the Other Co-Owner Pays You
The co-owner keeping the house has to produce the cash for your equity share and take over the mortgage. The most common route is a cash-out refinance: a new, larger loan in the buying co-owner’s name that pays off the old mortgage and generates the funds to pay you. Refinance closing costs typically run 2% to 6% of the new loan amount.1Bankrate. How Much Does It Cost To Refinance A Mortgage
Not every co-owner qualifies. Lenders evaluate the buying co-owner’s credit, income, and debt-to-income ratio on that person alone, not the combined household income that supported the original loan. When a refinance is not possible, alternatives include a home equity loan or line of credit stacked on the existing mortgage, personal savings or investments, or a seller-financed installment plan where you receive payments from your former co-owner over time. Each carries its own cost, timeline, and risk. Installment plans are the riskiest for the departing owner because you remain financially exposed to the property until the last payment clears.
The Due-on-Sale Clause Usually Is Not a Problem
Most mortgages include a due-on-sale clause letting the lender demand full repayment if ownership changes. Federal law blocks the lender from enforcing it in the buyout situations that come up most often. Under the Garn-St. Germain Act, a lender cannot accelerate the loan when the transfer goes to a spouse or children of the borrower, results from a divorce decree or legal separation, or passes to a relative after the borrower’s death.2Office of the Law Revision Counsel. 12 U.S. Code 1701j-3 – Preemption of Due-on-Sale Prohibitions
Buyouts between unrelated co-owners, such as business partners or friends who bought together, do not get that protection. A refinance moots the issue entirely because the old loan gets paid off.
Put the Deal in Writing
A written buyout agreement is the backbone of the transaction. In a divorce, it is typically part of the property settlement and gets folded into the divorce decree. At minimum, the agreement should cover:
- The buyout price, the property value it was calculated from, and how that value was determined.
- Payment terms: lump sum at closing, installments with a stated interest rate and default consequences, or a mix.
- A specific deadline by which the buying co-owner must complete the refinance and remove you from the mortgage.
- Deed transfer timing tied to the refinance, so your interest transfers only at or after the loan closes in the other co-owner’s name.
- Who pays closing costs, appraisal fees, outstanding property taxes, and any repairs needed before closing.
The actual transfer of ownership happens through a new deed. Quitclaim deeds are common in divorce buyouts and are the simplest form. A real estate attorney or title company handles the closing. Attorney fees for a straightforward residential closing typically run $500 to $1,500 as a flat fee, plus recording fees, notary charges, and any transfer taxes. Some jurisdictions exempt divorce-related transfers from transfer taxes, so check local rules before you budget.
Taxes on Your Side of the Buyout
What you owe depends on your relationship to the other co-owner and how the property was used.
If You Are Divorcing
Federal law treats a property transfer between spouses, or between former spouses when the transfer is related to the divorce, as a nontaxable event. No capital gains tax applies to the transfer itself. The spouse who keeps the house takes the original tax basis rather than a stepped-up basis at the buyout price, which affects the tax bill whenever that spouse eventually sells. The transfer must occur within one year after the divorce is finalized, or be required by the divorce agreement and happen within six years of the marriage ending.3Office of the Law Revision Counsel. 26 U.S. Code 1041 – Transfers of Property Between Spouses or Incident to Divorce
If You Are Not Divorcing
For unrelated co-owners or family members outside of a marriage, the IRS treats you as having sold your share. Capital gains tax may apply on any appreciation since acquisition. The primary residence exclusion can shelter up to $250,000 in gains for a single filer or $500,000 for a married couple filing jointly, if you owned and lived in the home for at least two of the five years before the sale.4Internal Revenue Service.

A tax professional who handles real estate can price out your exposure before you sign.
When the Other Co-Owner Will Not Buy or Sell
If your co-owner refuses to buy you out and refuses to sell, the legal remedy is a partition action, a lawsuit asking the court to end the co-ownership. For a single-family home, physical division is almost never workable, so courts typically order a partition by sale: the property is sold and the proceeds are divided according to ownership shares.
Partition actions are slow, expensive, and adversarial, and attorney fees can consume a meaningful share of the proceeds. In practice, the threat of filing is often what brings a reluctant co-owner to the table. A consultation with a real estate attorney about your partition rights can shift the negotiation before you ever file. Treat the lawsuit itself as a last resort after a good-faith buyout offer has failed.
