Selling an Inherited House: Probate, Taxes & First Steps

TL;DR: When you inherit a house, its cost basis usually resets to the fair market value on the date the owner died, not what they originally paid for it. That single rule is why most heirs owe little or no capital gains tax if they sell within a year or so of the death. Before you list the house, though, it typically has to clear probate and be retitled in your name (or the estate's) first.

You just found out you inherited a house, and now you're staring at two problems at once: the legal paperwork to actually own it, and the tax bill you're worried will follow when you sell it. The good news is the tax side is usually simpler than people expect, but the order of operations matters.

Okoniq Property Hub keeps a record of appraisal values, probate dates, and sale documents in one place, so you're not digging through email when your CPA asks for the paper trail months later.

What happens to the house during probate before it can be sold?

Probate is the court process that confirms who legally owns the property before it can be sold or retitled. Until an executor or personal representative is appointed and the estate is opened with the local probate court, no one, including a named heir, can sign a valid deed to sell the house.

Some estates skip this step entirely. If the house was held in a living trust, or titled with a transfer-on-death deed, or owned jointly with rights of survivorship, ownership can pass outside of probate court. If none of those applied, expect the executor to need "letters testamentary" or similar court authority before a title company will close a sale. State law controls the exact process and timeline, so check with a probate attorney in the state where the property sits rather than assume it matches a story you heard from a friend in another state.

While the estate is open, someone still has to pay the mortgage, insurance, property taxes, and utilities on the house. If the assessed value seems high relative to what the house would actually sell for, it's worth learning how to appeal your property tax assessment before the estate absorbs another year of inflated tax bills.

How is the cost basis calculated for an inherited house?

The cost basis of an inherited house is generally its fair market value on the date the previous owner died, not what they paid for it decades earlier. This is often called a "stepped-up" basis, and it's the single most important number in the entire sale.

Say the house appraised at $340,000 the day your mother died, and you sold it five months later for $335,000. Even though she bought the house for $80,000 back in 1985, your taxable gain is based on the $340,000 figure, not the $80,000 one. In this example, you'd actually report a small loss, not a gain. That's a very different outcome than if the original purchase price had carried over, which is what happens with a gift instead of an inheritance.

Getting that fair market value documented matters more than almost anything else in this process. A qualified appraisal dated close to the date of death, or a comparative market analysis from a local agent, is the paper trail an auditor would want to see. For the full mechanics, including what to do if you can't get a contemporaneous appraisal, see how to calculate cost basis on an inherited house.

What taxes do you actually owe when you sell an inherited house?

You owe capital gains tax only on the difference between the stepped-up basis and your eventual sale price, and inherited property is automatically treated as a long-term holding regardless of how long you personally owned it. That long-term treatment applies even if you sell the house one month after inheriting it.

If the house had been a rental before the owner died, and depreciation had been claimed against it, that prior depreciation generally does not carry over to you as recapture, because the basis reset wipes it out. If you turn the inherited house into a rental yourself after taking title, then sell it later, different rules kick in on your own depreciation. Read what happens to depreciation recapture when you sell before you decide whether to rent it out first or sell it outright.

Current capital gains tax rates and thresholds change with legislation, so don't rely on a number you remember from a prior tax year. Confirm the rate that applies to your income bracket on IRS.gov or with a CPA before you estimate what you'll owe.

| Scenario | Typical tax outcome | |---|---| | Sell within months of death, near appraised value | Little to no capital gains tax owed | | Hold for years, property appreciates further | Gain taxed on appreciation since date of death only | | Rent it out first, then sell | New depreciation and its recapture apply on top of basis rules |

What are the first practical steps after inheriting a house you plan to sell?

The first steps are opening the estate with the probate court, getting a documented fair market value as of the date of death, and deciding whether to sell as-is or make repairs first. Order these roughly in that sequence, because an appraisal that comes months after the death date is harder to defend as accurate.

Next, check the mortgage and insurance situation. Many lenders allow the loan to stay in place while the estate is open, but the homeowner's insurance policy usually needs to be updated to a "vacant property" or landlord policy once the previous owner is no longer living there. An empty house with an outdated policy is a real exposure if something goes wrong before closing.

If you and siblings or co-heirs disagree about selling versus keeping the property as a rental, settle that decision early. Every month spent deciding is another month of taxes, insurance, and upkeep coming out of the estate or your own pocket. If you do end up holding rental property afterward, you may eventually owe quarterly estimated tax payments on rental income, which is a different rhythm than the one-time capital gains question tied to the sale itself.

Should co-heirs sell together, or can one buy the others out?

Either works, but a buyout needs its own appraisal-backed valuation to avoid a dispute later. If three siblings inherit a house equally and one wants to keep it, that sibling typically needs to pay the others their share based on current fair market value, often financed through a new mortgage in their own name. Get the buyout price in writing and tied to a documented appraisal, the same one you'd want on file for the stepped-up basis calculation anyway. If gains ever get large enough that a swap into other investment real estate makes sense for one of the heirs, 1031 exchange basics is worth a look, though it only applies if the property is held for investment, not as a personal residence.

FAQ

Do I owe tax on an inherited house if I don't sell it?

No. Inheriting the house itself is not a taxable event for income tax purposes. Tax only becomes relevant when you sell, and it's calculated against the stepped-up basis, not the original purchase price.

What if the house sells for less than the appraised value at death?

You can report a capital loss in some cases, since the stepped-up basis becomes your cost for tax purposes just like any other asset. Talk to a CPA about how that loss can be used, since the rules differ depending on whether the property was held for personal use or as an investment after you inherited it.

How long does probate usually take before I can sell?

Timelines vary widely by state and by whether the estate is contested, so there's no single number that applies everywhere. Ask the estate's attorney for a realistic estimate based on your specific county's court schedule.

Does it matter if multiple siblings inherit the house together?

Yes, practically speaking. All co-owners generally need to agree to sell, or one needs to buy out the others, before a sale can close. Get any buyout valuation in writing and tied to a documented appraisal to avoid disputes later.

Can I deduct the cost of fixing up the house before selling it?

Repairs made to prepare an inherited house for sale are generally treated as selling expenses that reduce your gain, rather than a separate deduction. Keep every receipt and invoice, since this is exactly the kind of paper trail a CPA or auditor will ask for.
