Search for the salary needed to live in Washington and you'll get one statewide number. It won't answer the question a relocating buyer actually has, which is what it takes to buy where you want to live. Washington isn't one housing market. The county you choose can move the answer by more than $100,000 a year in household income. So here's the math, built the same way for every place, with every assumption on the table so you can swap in your own.
The model, with every assumption showing
I use one model so the only thing that changes from place to place is the price. The loan is a 30-year fixed with 10% down. The rate is 7.32%, Freddie Mac's Primary Mortgage Market Survey average for the week of October 22, 2026. Property tax is estimated at 1% of the price per year, homeowners insurance at $150 a month, and mortgage insurance at 0.5% of the loan per year, which applies with less than 20% down on a conventional loan. No HOA dues.
Those are planning assumptions, not a lender quote and not the actual tax bill on any specific house. Your real rate depends on your credit, loan type and the day you lock, and your real tax bill depends on the taxing districts the parcel sits in.
Then I hold the total housing payment to 28% of gross household income, meaning income before taxes and paycheck deductions. That 28% is a budgeting benchmark, not a lender's approval cutoff. Lenders look at your total debt against income, your credit and the loan program, and the limits vary. Some buyers will qualify above this benchmark and some won't qualify at these incomes.
Walking through the Kitsap math
Kitsap County's median sale price was $595,000 in September 2026, according to the NWMLS Local Market Update. Ten percent down is $59,500, which leaves a loan of $535,500.
At 7.32%, the monthly rate is 7.32 divided by 12, or 0.61%. Run that over 360 payments and principal and interest come to about $3,679 a month. Add $496 for property tax (1% of $595,000, divided by 12), $150 for insurance and $223 for mortgage insurance (0.5% of $535,500, divided by 12), and the estimated total is about $4,547 a month.
To keep $4,547 at 28% of gross income, multiply by 12 to get $54,564 a year, then divide by 0.28. That's about $194,900 of household income. Principal and interest are roughly 81% of the payment, which is why the rate and the loan size move the answer more than anything else.
County by county at today's rate
Pierce County's median was $580,000 in September 2026 (NWMLS). Using the same model, the payment is about $4,437 a month and the income benchmark is about $190,100. Pierce lands just under Kitsap on price, but it had more inventory relative to its sales pace, 3.7 months of supply against Kitsap's 3.0, so a prepared buyer there has more to compare.
King County's median was $950,000 in September 2026 (NWMLS). The same model produces a payment of about $7,171 a month and an income benchmark of about $307,300. The gap between King and Kitsap in this model is about $112,000 a year in household income, which is the affordability argument for the west side of the Sound in one number.
For context on the west and south ends of the region, I'll use Zillow's typical home values for September 2026, which are estimates of a typical home rather than sale medians. Zillow put Shelton at about $419K, which works out to a payment near $3,247 and income near $139,100. Bremerton, at about $479K, comes to roughly $3,690 a month and $158,100. Olympia, at about $526K, comes to roughly $4,038 and $173,000. Gig Harbor, at about $811K, comes to roughly $6,144 and $263,300.
What the rate did to the answer
In the video I used an illustrative 6.5% rate so the comparison wouldn't hinge on one week's number. Rates have moved since, so the figures here use the verified October 22 survey instead. At 6.5%, the same $595,000 Kitsap home would need about $182,300 of income. At 7.32% it needs about $194,900, roughly $12,600 more.
A year earlier, Freddie Mac's average was 6.19%, and at that rate the same home would need about $177,700. Kitsap's median rose 1.8% over the year. The money to buy the house rose a lot faster than the house did. That's why I tell buyers to make sure the purchase works at the rate they can get now, not a rate they hope to refinance into.
Three dials you control
The first is the share of income you're willing to spend. Keep the same $4,547 Kitsap payment and read it at different budgets: at 28% of gross income it takes about $194,900, at 25% about $218,300, and at 20% about $272,800. Which one fits depends on the expenses a mortgage calculator never sees, from child care and health care to retirement savings and the car that will need a transmission. A lender's approval is a financing decision. Your comfort level is a household decision.
The second is the down payment. Go from 10% to 20% down on the Kitsap median and the loan drops to $476,000, principal and interest fall to about $3,270, and mortgage insurance goes away. The payment drops to about $3,916, and the income benchmark falls to about $167,800, roughly $27,100 less a year. The trade is another $59,500 in cash. If that empties your reserves right after a cross-country move, the smaller loan may not be the smarter plan.
The third is where and what you buy. Shopping below the county median, choosing a town with lower typical values, or considering a condo or townhome all change the price input directly. A condo's HOA dues go into the payment, so compare the full monthly cost, not just the price.
Washington paycheck deductions to plan for
Washington doesn't tax wages, which matters if you're relocating from a state that does. But a Washington paycheck still has state deductions. The Paid Family and Medical Leave premium is 1.13% of wages in 2026, and employees can be charged up to 71.43% of it, about 0.81% of wages by my arithmetic, up to the Social Security wage cap. The WA Cares long-term care premium is 0.58% of wages, with no cap.
On $100,000 of covered wages, that's up to roughly $807 for Paid Leave and $580 for WA Cares, about $1,387 a year. I won't promise that a salary here equals a bigger one somewhere else, because that depends on your filing status and the state you're leaving. Compare the complete budget, and don't use a tax advantage to justify a payment that already feels tight.
Who this fits, and where to start
If your household earns around $140,000 to $160,000, this model points you toward the lower-priced towns on the west and south ends of the region, or toward a larger down payment. Around $190,000 to $195,000, the Kitsap and Pierce medians fit at a 28% budget. Above $300,000, King County's median comes into range. None of those are salary requirements. They're starting points for a search.
Put your own income, debts and down payment into the budget planner on this site, then check the cost-of-living page for everything beyond the mortgage. The compare tool will show you what each town on your list costs side by side, and the current listings page shows what your number actually buys right now. Don't just ask what salary it takes to live in Washington. Ask where your budget buys the life you want.
