How to Sell an Inherited Home in Washington State

What do you need to know about selling an inherited home in Washington state?

Selling an inherited home in Washington state typically involves navigating probate (which can take 6–12 months in King County), confirming who holds legal authority to sell, and taking advantage of the stepped-up basis - a tax rule that can eliminate capital gains if you sell shortly after inheriting. Washington's community property laws add an extra layer of tax benefit for married couples. If multiple heirs are involved, everyone must agree before the property can be listed, or a court process may be needed.

Inheriting a home in Shoreline, Seattle, or anywhere in King County is rarely as simple as it sounds.

You're often dealing with it during one of the harder stretches of life - and then you're handed a list of legal questions you never expected. Do I have to go through probate? Can I sell now or do I have to wait? What do I owe in taxes? What if my sibling doesn't want to sell?

These are the questions I hear most from heirs who reach out, and they deserve real answers - not vague legal disclaimers. Here's what you actually need to know.

Does the Home Have to Go Through Probate in Washington?

Not always - but usually yes, if the home was held in the deceased owner's sole name.

Washington state probate is discretionary, meaning it's not automatically required by law. But if the owner died without a Transfer on Death (TOD) deed or without placing the property in a revocable living trust, the home typically needs to go through the King County Superior Court probate process before it can legally be sold.

Here's the practical timeline: once probate is opened, a personal representative (also called an executor) is appointed by the court. If they're granted non-intervention powers - which is common in Washington, especially when there's a valid will - they can list, negotiate, and accept offers on the property without asking the court for permission at every step.

In King County, a straightforward probate case typically takes 6 to 9 months. More complex situations - large estates, disputes among heirs, unclear title - can stretch to 12 months or longer.

Important note: The King County Law Library updated its probate forms and instructions in June 2026 due to recent procedural changes in Washington state. If you're in the middle of this process, double-check with the court or a probate attorney that you're working from current forms.

Can you sell the home before probate is complete?

In most cases, yes - you can accept an offer and open escrow while probate is still active. The sale typically can't close until the personal representative has been officially appointed and has the legal authority to sign. Once those conditions are met, the proceeds go into the estate's accounts as part of the probate process.

If the previous owner had a TOD deed on file or held the property in a living trust, you may be able to skip probate entirely. An estate attorney can tell you quickly which situation you're in.

The Stepped-Up Basis: Why Selling Soon After Inheriting Usually Makes Financial Sense

This is the most important financial concept to understand - and most heirs don't know about it until after they've made decisions that cost them money.

When you inherit a home, your cost basis for tax purposes is reset to the property's fair market value at the date of the original owner's death. This is called a stepped-up basis.

Here's why it matters. Say your parent bought their Shoreline home in 1990 for $175,000. By the time they passed away in 2025, it was worth $850,000. That's $675,000 in appreciation - which, had they sold it themselves, would have been subject to capital gains taxes (minus their personal exclusion).

When you inherit it, your new cost basis becomes $850,000. If you sell for $850,000 shortly after inheriting, you owe nothing in capital gains. Not federal, not Washington state.

Washington's Community Property Advantage

Washington is one of nine community property states, and that matters here. When a married couple owns a home as community property and one spouse passes away, both halves of the property can receive a stepped-up basis - not just the deceased spouse's half. Most non-community property states only step up the deceased's 50%. Washington's rule can represent a significantly larger tax advantage.

Every situation is different, and you'll want to work with a CPA or estate attorney to document the stepped-up basis properly - specifically, getting a qualified appraisal dated close to the time of death. That appraisal becomes your supporting documentation for the IRS if questions arise later.

If you hold the property and it appreciates further after inheritance, that additional gain becomes taxable. Washington's 7% state capital gains tax applies to net gains above the annual threshold (roughly $262,000 as of recent years, adjusted periodically). This is another reason many heirs choose to sell reasonably soon after inheriting rather than holding indefinitely.

What If Multiple Heirs Are Involved?

This is where inherited property gets complicated - and sometimes emotionally fraught.

In Washington, if multiple people inherit a property, it's typically held as tenants in common, meaning each heir owns a percentage of the whole. Before anyone can list the home, all co-owners must agree on the sale.

Most families work it out. Common paths:

• Sell together: All heirs agree to list, split proceeds proportionally at closing.

• One heir buys out the others: One person pays fair market value for the other shares — requires financing or cash and a clear appraisal.

• Mediation: If opinions differ on price, timing, or whether to sell at all, a neutral mediator can help everyone reach agreement before it escalates.

If heirs can't reach an agreement, the last resort is a partition action - a lawsuit that asks the court to force a sale. Partition actions are slow, expensive, and contentious. They're the outcome everyone should be trying to avoid.

One thing I hear often: heirs assume this will be easy because the family is close. Sometimes it is. But the emotional weight of selling a parent's or sibling's home - the place with forty years of memories - can surface disagreements that nobody expected. Getting aligned on goals early, and using a neutral third party if needed, makes the whole process much smoother.

Getting Ready to Sell: The Practical Side

Once you have legal authority to sell and heirs are aligned, the process is much like any other home sale in the Seattle market - with a few nuances.

As-is vs. preparing the home. Many inherited homes haven't been updated in decades. The question of whether to invest in improvements before listing depends heavily on the home's condition, the neighborhood's price point, and your timeline. In Shoreline, where homes are currently selling in a median of 9 days and at 100.8% of list price, well-priced and well-presented homes still move quickly. That said, not every estate has the cash to fund renovations - and sometimes selling as-is to the right buyer is the smarter call. See Sell Your Shoreline Home As-Is or Fix It First: How to Decide for a detailed breakdown of that decision.

REET still applies. Washington's Real Estate Excise Tax is due at closing on inherited property sales, just as it is on any other home sale. The 2026 rates are 1.10% on the first $750,000, 1.28% on amounts between $750,000 and $1,525,000, plus an additional 0.50% King County local REET.

Working with an agent who's done this before. Inherited home sales have layers that a standard transaction doesn't - confirming who has signing authority, coordinating with the estate attorney, handling title with a deceased owner on record, and sometimes managing the property (and carrying costs) during a longer-than-average timeline. It's worth working with an agent experienced in these situations, not just any agent who happened to answer the phone.

This is exactly the type of situation I work with regularly. Every inherited home sale I've handled has looked different - different timelines, different family dynamics, different financial pictures - and that experience is what makes the difference when things get complicated.

Frequently Asked Questions

Do I have to pay taxes when I inherit a home in Washington state?

No - Washington has no inheritance tax. Heirs don't owe taxes simply for receiving the property. When you sell the inherited home, you may owe capital gains tax on any appreciation above the stepped-up basis (the fair market value at the date of death), but not on gains that occurred before you inherited it.

Can I sell an inherited house before probate is complete in Washington?

You can typically accept an offer and open escrow before probate closes, but the sale usually can't close until the personal representative has been formally appointed and has legal authority to transfer title. In some situations - like when the home was held in a living trust or had a Transfer on Death deed - probate may not be required at all.

What if one heir wants to sell and another doesn't?

All co-owners of an inherited property must agree to a sale. If heirs can't reach an agreement through discussion or mediation, any heir can file a partition action - a lawsuit asking the court to force a sale. Partition actions are a last resort; they're slow, costly, and hard on family relationships. Most situations resolve through communication and sometimes a neutral real estate agent or mediator who can facilitate the conversation.

How long does it typically take to sell an inherited home in King County?

The full timeline - from the date of death to closing - is typically 8 to 18 months when probate is involved. Simple probates with aligned heirs can close in 6 to 9 months. Complex estates or contested situations can take longer. If probate isn't required (TOD deed, living trust), the timeline shortens considerably - potentially to a standard 30-45 day closing once the property is listed.

Do I need a real estate attorney to sell an inherited home in Washington?

You don't legally need one, but it's strongly advisable - especially if the estate involves probate, multiple heirs, outstanding liens, or any ambiguity about who holds legal authority to sell. An estate attorney ensures the title transfer is clean and protects everyone involved from disputes down the road. Your real estate agent can work alongside the attorney, handling the market strategy and logistics while the legal side is handled properly.

Selling an inherited home is one of the most complex transactions a homeowner - or heir - faces. The legal pieces, the tax implications, and the family dynamics all have to come together, often while you're still processing the loss that put you here in the first place.
