Years Guiding Seattle Buyers & Sellers

Homeowners insurance used to be an afterthought in a Seattle home purchase — a line item you'd shop for after closing. That's changed. After a sharp run-up in rates over the past several years, insurance costs are now a real factor buyers weigh, sellers should anticipate questions about, and everyone in a transaction needs to understand. TC Wu breaks down what's driving the increase and what it means for you.

What's Driving the Increase — And Where Things Stand Now

Four things every buyer and seller should understand.

1
The Trend

Rates Have Risen Sharply Since the Pandemic

Washington homeowners insurance rates climbed roughly 55% between 2020 and 2025, according to a LendingTree analysis, with most of that increase concentrated in 2023 through 2025. The pace has since slowed considerably — the state's Office of the Insurance Commissioner reported an 8.9% average base rate increase in 2025, and requested rate changes for 2026 have actually ticked down slightly, suggesting the sharpest increases may be behind us.

💡 Market Insight
Washington still ranks among the more affordable states for homeowners insurance nationally, even after these increases — this is a rate-of-change story, not an affordability crisis on the scale seen in states like Florida.
2
The Cause

Construction Costs and Climate Risk Are the Main Drivers

Rising rebuild and repair costs — driven by supply chain disruptions and labor shortages — are the primary factor behind higher premiums, according to state insurance regulators. Washington homeowners' aggregate claim costs rose from roughly $941 million in 2018 to over $2 billion annually by 2023–2024. Increasing wildfire and flood risk tied to climate change has added further pressure, particularly in wildfire-prone areas east of the Cascades.

💡 Market Insight
Homes in wildfire-adjacent or flood-prone areas may see steeper premium increases than the statewide average — factor this into your search if you're considering more rural or forested King County locations.

Local Numbers

What Seattle-Area Homeowners Are Actually Paying

Seattle-area homeowners currently pay around $1,406 annually for homeowners insurance on average, with Bellevue slightly higher at roughly $1,430 — both well below the national average of nearly $3,000. Home age matters too: homes built around 2020 average roughly $1,146 annually to insure, compared to about $1,486 for homes from the 1980s, since older electrical, plumbing, and roofing systems carry higher perceived risk.

💡 Market Insight
If you're comparing an older home to a newer one, factor the insurance premium difference into your total monthly cost comparison — it's a real, ongoing gap, not a one-time cost.

Transaction Impact

How This Is Showing Up in Real Transactions

More buyers are now requesting an actual insurance quote for a specific property before writing an offer, rather than assuming a generic estimate will hold. Sellers of older homes are increasingly fielding questions about roof age, electrical panel type, and prior claims history, since these details can meaningfully move a buyer's projected monthly cost — and in some cases, their financing approval.

💡 Market Insight
Sellers of older homes can get ahead of buyer questions by having recent roof, electrical, and plumbing documentation ready before listing — it can prevent insurance concerns from stalling a deal later.
"A few years ago, insurance was something buyers dealt with after closing. Now I tell every buyer to get a real quote before they write an offer — not after. It's become a genuine part of affordability, and ignoring it until the last minute can create real surprises."

How Buyers and Sellers Should Respond

Four practical steps for today's insurance environment.

1

Buyers: Get a Property-Specific Quote Before You Offer

Don't rely on a generic estimate — request an actual quote for the specific home so your total monthly cost picture is accurate before you're under contract.

2

Sellers: Have Home Age and System Documentation Ready

Roof age, electrical panel type, and any recent updates can significantly affect a buyer's insurance quote — have this documentation available early.

3

Shop Multiple Insurance Carriers

Washington's insurance market remains competitive with multiple carriers — comparing quotes can reveal meaningful differences even for the same property.

4

Ask About Bundling and Security Discounts

Bundling home and auto policies, or adding monitored security systems, can meaningfully offset rising premiums — ask any carrier you're quoting about available discounts.

Frequently Asked Questions

Common insurance and home-buying questions answered by TC Wu.

The main drivers are rising construction and repair costs due to supply chain and labor pressures, along with increasing climate-related risks like wildfires and flooding. Statewide claim costs more than doubled between 2018 and 2024, pushing insurers to raise rates to keep pace — though the pace of increases has slowed significantly heading into 2026.
Yes, relatively speaking. Even after recent increases, Washington's average annual premium remains roughly half the national average, and well below high-risk states like Florida, Louisiana, or Texas. The story in Washington is more about the pace of recent increases than the absolute affordability of coverage.
Yes, it's increasingly recommended. A property-specific insurance quote gives you an accurate picture of your true monthly housing cost, since factors like roof age, home age, and location can meaningfully affect your premium. Waiting until after you're under contract can lead to unwelcome surprises late in the process.
