Inherited a Home in Seattle? A 2026 Guide to Probate, Taxes, and Whether to Sell, Rent, or Keep It

What Happens to a House When Someone Dies in Washington State

If the deceased owned the home in their own name — not in a trust, and without a transfer-on-death deed — the property must typically pass through Washington's probate process before it can be sold or transferred. Probate is the court-supervised process of validating a will (or determining heirs if there is no will), appointing a personal representative (executor), settling debts, and distributing remaining assets, including real estate.

For a straightforward estate with a valid will, no disputes among heirs, and no significant creditor claims, Washington probate typically takes four to eight months from filing to closing. Estates become more complicated — and slower — when there is no will (intestate succession), when heirs disagree about how to proceed, when the deceased lived out of state, or when there are outstanding debts or tax issues to resolve. Contested probates can extend well past a year.

If the home was held in a revocable living trust, or if Washington's transfer-on-death deed was used, the property can often pass directly to the named beneficiary without probate — significantly shortening the timeline. If you're unsure which situation applies, the estate's attorney or personal representative can confirm within the first few weeks.

The Stepped-Up Basis: Why It Matters More Than Almost Anything Else

The single most valuable — and most misunderstood — element of inheriting property is the stepped-up cost basis. When you inherit a home, your cost basis for tax purposes resets to the property's fair market value on the date of the original owner's death, rather than what they originally paid for it decades earlier.

Here's why this matters: if a parent purchased a Seattle home in 1985 for $80,000, and it's worth $950,000 at the time of their death, an heir who sells it shortly after for $970,000 owes capital gains tax on only the $20,000 gain since inheriting it — not the roughly $890,000 of appreciation that occurred during the original owner's lifetime. Without the step-up, that entire gain would typically be taxable.

This is fundamentally different from receiving a home as a gift during someone's lifetime, which carries over the giver's original basis with no step-up. Confusing gifted property with inherited property is one of the costliest mistakes heirs and their families make — it's worth confirming which situation applies before making any assumptions about tax exposure.

The practical implication: heirs who sell an inherited home within a reasonable window after the date of death usually owe little to no capital gains tax, since fair market value at death and current sale price tend to be close. The longer you hold the property before selling, the more the stepped-up basis erodes as market appreciation accumulates on top of it.

Selling an Inherited Home: The Practical Path

Once probate has closed — or the personal representative has authority to act — selling an inherited home follows a similar process to any other sale, with a few added considerations. Inherited homes frequently carry deferred maintenance: an aging roof, outdated electrical or plumbing, decades-old kitchens and bathrooms. Buyers factor this into their offers, so understanding your as-is value versus your prepared-for-sale value is an early and important decision.

For many heirs, an as-is sale — priced to reflect the home's condition, marketed to buyers who expect to renovate — is the faster, lower-stress path, especially when heirs live out of the area or don't want to manage a renovation before selling. For others, modest pre-listing preparation (deep cleaning, decluttering decades of belongings, minor repairs) can meaningfully increase the final sale price relative to the cost.

When there are multiple heirs, everyone with a legal interest generally needs to agree to the sale and its terms, and proceeds are distributed according to the will or Washington's intestate succession rules. Establishing clear communication and expectations among co-heirs before listing prevents the disagreements that most often derail or delay these sales.

Renting It Out Instead: What Changes

Some heirs consider keeping the inherited home as a rental rather than selling. This is a legitimate option, but it changes the financial picture in several ways. The home stops being eligible for any owner-occupant tax treatment and becomes a straightforward investment property — subject to landlord-tenant law, ongoing maintenance responsibility, and the practical demands of managing a rental, whether personally or through a property manager.

The stepped-up basis still applies and still matters — it becomes the depreciable basis for tax purposes going forward, and it's still the reference point for calculating gain whenever you eventually do sell. But every year you hold and rent the property, additional appreciation accumulates on top of that stepped-up basis, gradually increasing the taxable gain a future sale would trigger.

Renting to a family member introduces its own complications — below-market rent to a sibling or relative can affect how the IRS treats the property for deduction purposes, and it can create friction among co-heirs who may prefer to sell and receive their share in cash rather than wait on rental income distributions.

Keeping It: Moving In or Buying Out Co-Heirs

If you want to keep the home for yourself — whether to live in it or simply hold onto a family property — and there are other heirs with a legal interest, you'll typically need to buy out their shares. This usually involves an independent appraisal to establish fair market value, followed by a refinance or cash payment to compensate co-heirs for their portion of the equity.

Washington does not reassess a home's property tax based on inheritance or change of ownership the way some other states do — property tax assessments here are tied to periodic county valuations rather than triggered by a transfer. That said, confirming the current assessed value and any exemptions with King County (or the relevant county assessor) early in the process avoids surprises.

Moving into an inherited family home is often as much an emotional decision as a financial one. It's worth having a candid conversation with a real estate advisor about the home's actual condition, what it would take to make it truly yours, and how that compares to the alternative of selling and purchasing something suited to your own life.

When Multiple Siblings or Heirs Disagree

Disagreement among heirs is common and rarely about the money alone — it's frequently tangled up with grief, family history, and differing financial circumstances. One sibling may want to sell quickly for cash, another may want to keep the home, and a third may be indifferent but resentful of how the conversation is being handled.

The most common resolution structures are: a buyout, where one heir purchases the others' shares at appraised value; a sale with proceeds split according to each heir's legal interest; or, in persistent disputes, mediation or — as a last resort — a partition action through the courts, which is slower and more expensive than either of the first two options.

A real estate advisor with no financial stake in which outcome the family chooses can be genuinely useful here — providing an objective, current market valuation and walking through the practical trade-offs of each path, without the emotional weight that makes these conversations hard to have among family members directly.
