Introduction
Inheriting a house with a sibling can get complicated pretty quickly. One sibling may want to keep the house because it has sentimental value, while another may need the money or simply want to sell. Even when everyone gets along, deciding what the property is worth and what each person should receive can become difficult.
I see this situation regularly in my practice. In most cases, the family ends up considering two main options: one sibling buys out the other sibling's share, or everyone agrees to sell the property and divide the proceeds.
Both options can work. The important thing is understanding what each one involves before making a decision.
Quick Summary
If you inherit a house with a sibling, you can usually either buy out their ownership share or sell the property and divide the proceeds. A buyout may make sense when one sibling wants to keep the home and can afford it. Selling may be simpler when no one wants the property or a buyout is not financially practical.
What Does Buying Out a Sibling Actually Mean?
Buying out a sibling simply means paying them for their share of the property so that you can keep the house.
For example, assume you and your sister each inherit 50% of your parents' home. You want to keep it, but your sister would rather receive the value of her share. Instead of selling the house to someone else, you can agree on a value, pay her for her ownership interest, and become the sole owner.
The first question when figuring out how to buy out a sibling is usually what the property is actually worth. Once you know that, you can determine the equity in the property and what each person's share is worth.
This is also where many inherited property disputes begin. The siblings may agree that a buyout makes sense but disagree about the home's value, repairs, expenses, or how much each person should ultimately receive.
Before You Decide, Find Out Who Actually Owns the House
Before talking seriously about a buyout, you need to know where the property is legally sitting.
The house may still belong to an estate, it may be held in a trust, or title may have already transferred directly to the heirs. That matters because the person who has authority to transfer the property may be an executor or trustee rather than the individual beneficiaries.
If the estate still needs the house as part of the administration process, a buyout may also have to wait.
Trusts can create additional options. In some situations, a trustee may be able to make what is called a non-pro-rata distribution. That might mean one beneficiary receives the house while another receives other assets of comparable value.
The timing and structure of these transactions can affect California property taxes, so this is something I would look at before title changes hands rather than trying to fix it afterward.
Buyout vs. Sale: Key Differences at a Glance
Here is a simple comparison of the two options:
| Issue | Buying Out a Sibling | Selling the Property |
| Who keeps the house? | One or more siblings | Nobody |
| Upfront money needed? | Usually | Usually not |
| Financing needed? | Often | Usually handled by the buyer |
| Property valuation needed? | Yes | Yes |
| Selling costs? | May be negotiated | Usually deducted at closing |
| Tax considerations? | Yes | Yes |
| Common disagreement | Value and credits | Whether or when to sell |
How Does a Sibling Buyout Work?
When everyone agrees, the process can be fairly straightforward. The siblings determine the property's value, calculate the ownership interest being purchased, arrange financing, prepare the transfer documents, and record a new deed.
In my experience, the paperwork usually is not the hardest part. Getting everyone to agree on the numbers is where problems tend to arise.
How Does Selling the Property Work?
If everyone agrees to sell, the house can generally be listed like any other property.
Once it sells, the mortgage, liens, commissions, closing costs, and other appropriate expenses are paid. The remaining proceeds are divided according to each person's ownership interest, subject to any credits or adjustments that the owners have agreed to or that a court determines are appropriate.
How Do You Calculate a Fair Buyout Price?
A fair buyout should start with a realistic value for the property and a clear understanding of how much equity is actually in the home.
Start With a Professional Appraisal
I would not recommend basing a major sibling buyout on a Zillow estimate or someone's opinion about what the house should be worth.
A professional appraisal gives everyone a neutral starting point. If there is already disagreement within the family, having an independent value can also prevent a lot of unnecessary arguing.
Account for the Mortgage and Liens
If the house has a mortgage or liens against it, those obligations reduce the equity in the property and need to be considered when negotiating a voluntary buyout.
Hypothetical selling costs are different. The siblings may agree to take those costs into account when negotiating a voluntary buyout, but they are not automatically deducted in every situation.
A court-ordered buyout under California law works differently. In that situation, the purchase price is based on the court-determined value of the property multiplied by the selling owner's fractional ownership interest.
The basic calculation is fairly easy.
Suppose the house is worth $600,000 and there is a $200,000 mortgage.
That leaves:
$600,000 - $200,000 = $400,000 in equity
If two siblings each own 50%, one sibling's share would be:
$400,000 × 50% = $200,000
So $200,000 would be the starting point for discussing that sibling's buyout in a voluntary transaction.
What About Repairs, Taxes, and One Sibling Living in the House?
This is where the calculation can become more complicated.
Suppose one sibling has lived in the house for two years while the other has paid most of the property taxes and insurance. Maybe one sibling also spent $25,000 repairing the roof, plumbing, or another major part of the property.
Those things can matter.
Depending on the circumstances, the owners may need to account for expenses paid by one person, benefits received by another, and other financial contributions. These issues are often handled through credits and offsets when the buyout is completed or when the proceeds of a sale are divided.
This is one reason I prefer to get these issues worked out in writing rather than relying on informal agreements between family members.
How Can You Finance a Sibling Buyout?
Once you know approximately what the sibling's share is worth, the next question is how you are going to pay for it.
There are several common options.
Paying Cash
If the sibling keeping the property has enough cash available, this is usually the simplest approach. The selling sibling receives the agreed amount and transfers their ownership interest.
Refinancing or Getting a New Mortgage
Most people do not have hundreds of thousands of dollars available to buy out a sibling in cash.
In that situation, the sibling keeping the house may refinance the existing mortgage or obtain new financing that provides enough money to complete the buyout.
I recommend looking into financing early because the lender will have its own income, credit, appraisal, and underwriting requirements.
Using a Payment Plan
Sometimes the siblings agree that the person keeping the house will pay the other sibling over time.
That can work, but it should be documented properly.
If the arrangement involves seller financing, the interest rate also matters. The IRS publishes Applicable Federal Rates, commonly called AFRs. Using an interest rate below the applicable federal rate can create tax issues involving imputed interest or gifts.
Before signing this type of agreement, I would have a CPA confirm the current AFR and explain the tax consequences.
What Taxes Should You Think About?
Two tax issues come up frequently when siblings are dealing with an inherited home: capital gains taxes and California property tax reassessment.
Capital Gains and Stepped-Up Basis
Inherited property generally receives a new tax basis based on its value at the owner's death. You may hear this referred to as a stepped-up basis.
That can reduce the amount of taxable capital gain compared with a property that was purchased many years earlier for a much lower price.
The actual tax consequences will depend on the property's basis, its value when inherited, the eventual sale or buyout price, and each owner's circumstances. For that reason, this is another area where I recommend involving a CPA before completing the transaction.
Property Tax Reassessment Under Proposition 19
California's Proposition 19 is especially important with inherited property.
If siblings already own the property and one sibling later purchases another sibling's interest, the purchased interest may be reassessed at its current value.
Things can work differently when property is still held in a trust or estate. In some situations, the way a trustee distributes property among beneficiaries may affect the property tax result. This is why I would look at the proposed distribution before transferring the house to several siblings and then arranging a buyout afterward.
Proposition 19 also has specific requirements for qualifying parent-child transfers involving a family home. Among other requirements, the eligible beneficiary generally needs to use the home as a principal residence and satisfy California's filing requirements.
These rules are detailed enough that I would not make a decision about an inherited California home without first understanding how the proposed transfer will affect the property's tax assessment.
What Happens If You and Your Sibling Cannot Agree?
Sometimes there simply is no agreement.
One sibling wants to sell immediately. Another refuses to sell because they want to keep the family home. One person thinks the property is worth $700,000 while another believes it is worth $900,000.
When co-owners cannot resolve those issues themselves, California law allows a co-owner to file a partition action.
A partition action asks the court to resolve the co-ownership dispute. Depending on the circumstances, that can ultimately result in a sale of the property or another resolution allowed by California law.
California also has a specific court buyout process that can apply in qualifying partition cases.
When a sale has been requested, the court can determine the value of the property under California Code of Civil Procedure section 874.316. Eligible co-owners then have an opportunity to elect to purchase the interests of the owners who requested the sale.
Under California's cotenant buyout statute, an eligible co-owner generally has 45 days after the required notice to elect the buyout. The purchase price is based on the court-determined value of the entire property multiplied by the selling co-owner's fractional ownership interest.
That procedure can be important because a sibling who wants to keep the house may still have an opportunity to do so even after a partition case has been filed.
You can also read more about whether siblings can force the sale of inherited property and the circumstances in which someone may be able to stop or avoid a partition sale.
How Underwood Law Can Help
A large part of my practice involves property owners who agree on some things and strongly disagree on others.
Sometimes the best solution is helping the family work through the value of the property, ownership percentages, expenses, and credits so they can reach a voluntary buyout.
Other situations require a partition action because one owner will not sell, cooperate, or agree to reasonable terms.
Either way, I want my clients to understand what the property is worth, what their ownership interest means, and what options California law gives them before they make a major financial decision.
If you are trying to settle a co-ownership dispute, structure a sibling buyout, or determine whether legal action is necessary, our partition action attorneys can review the situation with you.
You can also schedule a consultation with Underwood Law to discuss your property and the options available.
Conclusion
Buying out a sibling can allow you to keep an inherited home in the family, but the value and financing need to make sense. Selling may provide a simpler way for everyone to receive their share and move forward.
Whichever direction you are considering, start with a reliable property value and understand the legal and tax consequences before signing anything.
Frequently Asked Questions
Can one sibling force the other to sell instead of allowing a buyout?
A co-owner can generally ask a court to resolve jointly owned property through a partition action. Whether the property is ultimately sold or a buyout is available will depend on the type of property, the ownership, and the facts of the case.
What happens to the mortgage when one sibling buys out the other?
Changing ownership of the property does not automatically remove someone from an existing mortgage. The loan may need to be refinanced or otherwise addressed with the lender as part of the buyout.
Can I buy out my sibling before probate closes?
Possibly. It depends on how the estate is being administered, who currently owns the property, and who has authority to transfer it. The executor or administrator may need to complete certain steps first.
Does the sibling living in the house owe rent to the other siblings?
It depends on the circumstances. Exclusive occupancy can become part of the accounting between co-owners, particularly when one sibling has received the benefit of living in the property while other owners have paid expenses.
Who pays property taxes and insurance until the buyout closes?
The owners can agree on how those expenses will be handled. If one owner pays more than their share, those payments may later be considered when the owners calculate credits and offsets.
Can I buy out one sibling but not the others?
Yes, that may be possible. You could purchase one sibling's ownership interest while the remaining siblings continue to own their respective shares of the property.
What documents finalize a sibling buyout?
The exact documents depend on the transaction, but a buyout commonly involves a written agreement, a deed transferring ownership, closing or escrow documents, and any documents required by the lender.
Does the mortgage lender have to approve the ownership transfer?
It depends on the existing loan and the type of transfer. Federal law provides protections for certain property transfers, but those protections do not apply to every sibling buyout. Before transferring title, review the loan documents and confirm how the lender will treat the transaction.
