The short answer
At today's Seattle prices and rents, and using our standard assumptions, owning does not overtake renting within 30 years.
Seattle reaches that conclusion by a completely different route than the other expensive metro on this site. In Austin, the problem is what the house costs you every month. In Seattle, the monthly costs are among the lowest of the metros we cover. The problem is the price of admission.

| Effective property-tax rate | 0.99% | Washington assesses at 100% of market value and revalues every parcel every year, so a buyer's basis is the price paid. The 2026 consolidated levy rate for Seattle levy code 0010 — every state, county, city, school, port, transit, library and EMS levy that applies to the parcel, summed — is $9.90845 per $1,000 of assessed value. Washington grants no general homestead exemption; the only residential relief is the senior and disabled-person exemption, which takes the same parcel to $4.24803. On a $774,216 purchase that is $7,671 a year — 0.9908%, rounded to 0.99% to match the precision we use elsewhere. Rates vary across the CBSA: King County's 2026 average is 0.91% ($8.4bn of tax on $920bn of assessed value), and Pierce County's codes run above Seattle's. Why not the Census ratio: Washington has no assessment cap and no reset on sale, so the ACS ratio is not measuring a different taxpayer here — which is exactly why this metro had to be checked rather than assumed. What it is measuring is a different levy year and a different denominator: 2019-2023 taxes against an all-homes median value of $673,500, where this page prices a single-family home at $774,216 at 2026 levy rates. The 0.87% it produces understates a 2026 Seattle buyer's bill by about $935 a year. For the record, that ratio is 0.87% — $5,832 median taxes paid ÷ $673,500 median home value for CBSA 42660, per US Census Bureau, American Community Survey — tables B25103 (median real estate taxes paid) and B25077 (median home value), metro level (2023 5-year estimates).King County Assessor, 2026 Codes and Levies — consolidated levy rate by levy code, City of Seattle levy code 0010; county-wide totals per the Assessor's 2026 property-tax overview (2026 tax year) |
| Homeowner's insurance | $1,058 / year | King, Pierce and Snohomish Counties. Washington publishes no premium data below the state level, so this is the NAIC's 2023 Washington HO-3 average of $1,232 — written premium over written exposures — moved onto the metro by the Seattle CBSA's position in the quoted series: $1,516 against a $1,766 Washington average, a ratio of 0.858. Both sides of that ratio are priced at $300,000 of coverage, so it measures geography and nothing else. $1,232 x 0.858 = $1,058. The level is a 2023 figure, the most recent written data the NAIC publishes, so it trails the 2026 price and rent on the rest of this page. On the one series where the same thing can be measured, Texas, written premiums rose 25% between 2023 and 2025. Treat this as a floor. This page previously published $1,516, a quoted premium from a rate-comparison sample at a fixed $300,000 of coverage. Quotes run above what insurers actually write, so we moved to the written figure.NAIC, Dwelling Fire, Homeowners Owner-Occupied, and Homeowners Tenant and Condominium/Cooperative Unit Owner's Insurance Report: Data for 2023 (published July 2026), Table 4 — average premium by policy form, HO-3, written premium divided by written exposures.

Why Seattle lands here
Seattle has the second-highest price-to-rent ratio of the metros we cover at 18.2, behind Los Angeles. A typical home is $774,216; a typical single-family rental is $3,541 a month. You are paying roughly eighteen years of rent to own the asset outright.
What makes Seattle genuinely interesting is that its carrying costs are cheap relative to the price. The effective property-tax rate is 0.99% — about two thirds of Austin's — and insurance runs $1,058 a year, the lowest figure in our set and less than a fifth of Miami's. Washington has no state income tax and an insurance market largely spared the hail, hurricane, and wildfire losses that have repriced Colorado, Florida, and Texas. As a share of the purchase price, tax and insurance together come to 1.13% a year here, third-lowest in our set behind Phoenix and Denver.
That tax rate is derived, not taken from the Census. Washington assesses every parcel at 100% of market value and revalues it every year, with no cap for long-tenured owners and no reset on sale, so unlike Miami or the Texas metros there is no gap here between what an incumbent pays and what a buyer pays. What there was instead is a stale rate: we had been publishing the Census ratio of 0.87%, which averages 2019–2023 bills against an all-homes median value of $673,500, while this page prices a single-family home at $774,216. Seattle's consolidated 2026 levy rate — every state, county, city, school, port, transit, library and EMS levy on the parcel, and Washington grants no general homestead exemption — is $9.90845 per $1,000, or 0.99%. On this page's price that is $7,665 a year rather than $6,736: about $935 more. King County's 2026 average is 0.91%, and Pierce County's rates run above Seattle's.
That figure needs its own sentence, because it is the one input on this page we cannot source locally. Washington publishes no premium data below the state level — no county series, no metro series, nothing. So $1,058 is the NAIC's Washington HO-3 average of $1,232, which is written premium divided by written exposures across the whole state, moved onto this metro by the one local signal we do have: in a quote series priced at a fixed $300,000 of coverage, the Seattle CBSA sits 14% below the Washington average. That ratio measures geography and nothing else, because the coverage is identical on both sides. The catch is vintage: the NAIC's figure is for 2023, the most recent written data it publishes, while everything else on this page is 2026. Texas premiums rose 25% over those same two years. Read $1,058 as a floor.
So Seattle is not expensive to hold. It is expensive to enter.
That shows up in one number: $171,828 in down payment and closing costs — second only to Los Angeles, and far above everywhere else. In our model both people start with that same sum. The buyer converts it into a house. The renter invests it. At a 7% return, $171,828 compounding for thirty years is an enormous head start, and Seattle's modest carrying costs are not a big enough monthly advantage to run it down.
Month one looks like this: $5,291 to own versus $3,556 to rent — a gap of roughly $1,700. The buyer is paying more every month and gave up the larger invested balance.
The assumption that decides it
Because Seattle's case against buying is almost entirely an opportunity-cost argument, it is the metro most sensitive to what you assume that opportunity is worth. It swings further than any other page here.
At our default 7% return, owning never catches up in 30 years. At 5%, owning breaks even in year 12 — inside a long ownership period, though past the point most owners have sold.
Every page on this site that says "never" at 7% comes back inside 30 years at 5%, so that swing is not unique to Seattle. What is unique is how little else moves the answer here. If you take away a single thing from this page, make it that: in Seattle, the rent-versus-buy question is really a question about your expected investment return, and anyone who answers it without telling you their assumed return has not answered it at all.
What we are not modelling, and where it cuts
Washington's real estate excise tax. Our model applies national-average transaction costs and assumes no transfer tax, which is right for many states and wrong for Washington. REET is charged on a graduated state schedule — 1.10% on the first $525,000 of sale price and 1.28% on the portion above it — and most counties and cities add a local increment on top of that. On a $774,216 sale, the state portion alone is about $8,965.
REET is customarily paid by the seller, so it does not appear in the buyer's cash to close. But in our model the owner's net worth is measured as what they would clear if they sold today, so a real Seattle sale nets less than we show. The break-even figure on this page is, if anything, optimistic about owning. Adding REET makes the case for buying slightly worse, not better.
One national appreciation rate. As on every metro page here, we assume 3.5% annual price growth rather than forecasting Seattle specifically. Seattle has outperformed the national average over some long windows and badly underperformed it over others. If you hold a view, put it in the calculator rather than taking ours.

Worth reading alongside this: the rent-to-price ratio, which explains why a ratio of 18.2 behaves so differently from one of 11, and what your down payment could have earned instead, which is the argument this entire page rests on.
