Cost of Buying a House in Seattle: A Budget Guide
A Seattle home budget built from dated Census, Freddie Mac and CFPB figures, covering cash to close, the monthly payment and the ongoing costs buyers tend to forget.
One $80K income can support very different home prices depending on rate, debts, down payment, taxes, and insurance. Here are three side-by-side scenarios, a cash-to-close table, and a take-home budget check.

How much house you can afford on $80k comes down to your rate, other debts, down payment, and local taxes and insurance. Under the illustrative assumptions below, a conservative budget points to roughly $270,000, a moderate one to about $370,000, and an aggressive budget to around $480,000, all at 20% down. The spread is the point: there is no single right number, only the one that fits your assumptions and your real budget.
This is general education, not personalized advice. A loan officer or HUD-approved housing counselor can run your actual numbers.
Start with gross monthly income: $80,000 ÷ 12 ≈ $6,667. The examples use three placeholder ratios of that income: 28% (about $1,867) for conservative, 36% (about $2,400) for moderate, and 45% (about $3,000) for aggressive.
Because the examples assume no other monthly debts, each row's housing budget is simply its ratio times gross income. The 28% and 36% figures echo the familiar "28/36" pairing, and 45% is a stress-case assumption. Ask each lender which ratios it uses for your loan.
The baseline rate for the examples is 7.18%, the 30-year fixed-rate average for the week of November 5, 2026, per Freddie Mac's Primary Mortgage Market Survey. Rates move weekly, so rerun the math with a current quote before relying on any figure.
Two calculators can give an $80k earner very different answers because each one bakes in different inputs: the interest rate, the debt-to-income (DTI) ratio, the down payment, and the tax and insurance figures. Change any one and the price moves. That is why a single quoted price without its assumptions isn't much use.
Rates alone can shift the answer within weeks. Freddie Mac's 30-year fixed average was 7.40% for the week of October 15, 2026, then 7.18% for the week of November 5.
Example: take a $300,000 loan over 30 years (n = 360 months). Using M = P·r(1+r)^n / ((1+r)^n − 1), a 7.18% rate gives r ≈ 0.005983 and M ≈ $2,032. At 7.40%, r ≈ 0.006167 and M ≈ $2,077, so a 22-basis-point move adds about $45 a month.

The table below shows what the same $80k income supports at three DTI levels. Everything here is an illustration built on these assumptions:
| Scenario | Ratio of gross income | Housing budget | Left for loan payment (and mortgage insurance) | Price at 20% down (loan) | 10% down | 5% down | 3.5% down |
|---|---|---|---|---|---|---|---|
| Conservative | 28% | $1,867 | $1,467 | $271,000 ($217,000) | $227,000 | $215,000 | $211,000 |
| Moderate | 36% | $2,400 | $2,000 | $369,000 ($295,000) | $309,000 | $293,000 | $288,000 |
| Aggressive | 45% | $3,000 | $2,600 | $480,000 ($384,000) | $402,000 | $381,000 | $375,000 |
The monthly budget mostly caps the loan size, and the down payment is added on top of it. That is why a bigger down payment buys a higher price at the same payment. It also lowers the loan, which helps because mortgage insurance is typically required when the down payment is less than 20% of the price.
Mind the cash side as well. Twenty percent down is about $54,000 on the conservative $271,000 home and about $74,000 on the moderate $369,000 one. Putting 3.5% down on the moderate $288,000 price is about $10,100.
A mortgage bill has several layers. Here is what to look for on a Loan Estimate:
Tax and insurance costs depend on where you buy, so look up real figures for the area rather than using a national average. Our budget guides for Austin and Seattle show how to build that local picture.

The next table starts from the moderate scenario at 10% down (about $309,000, using the same assumptions as above) and changes one input at a time. It's an illustration, so plug in your own numbers to see your version.
| Change | Approx. price | Versus baseline |
|---|---|---|
| Baseline: 36%, 10% down, 7.18%, $400 taxes and insurance | $309,000 | n/a |
| Add a $100/month car or student loan payment | $294,000 | −$15,000 |
| Rate 1 point lower (6.18%) | $340,000 | +$31,000 |
| Rate 1 point higher (8.18%) | $282,000 | −$27,000 |
| Lower taxes and insurance ($250/month) | $332,000 | +$23,000 |
| Higher taxes and insurance ($650/month) | $270,000 | −$39,000 |
Small monthly debts matter because they count against the same total-debt ceiling as your housing payment. Rate shifts are not hypothetical, as the weekly moves cited earlier show.
Closing costs are the fees paid on the day the purchase is finalized. They include title insurance, credit report and appraisal fees, origination fees, and more.
The CFPB reported median closing costs of $6,000 in 2022, and its analysis found median total loan costs rose by over 36% from 2021 to 2023. Treat $6,000 as a starting placeholder and replace it with the figure on a real Loan Estimate.
The table below assumes $6,000 in closing costs and a $6,000 reserve cushion. Both are assumptions, so size the reserve to your own comfort.
| Home price | Down payment at 3.5% | Down payment at 10% | Closing costs (placeholder) | Reserve cushion (assumption) | Total cash at 3.5% down | Total cash at 10% down |
|---|---|---|---|---|---|---|
| $250,000 | $8,750 | $25,000 | $6,000 | $6,000 | $20,750 | $37,000 |
| $300,000 | $10,500 | $30,000 | $6,000 | $6,000 | $22,500 | $42,000 |
| $350,000 | $12,250 | $35,000 | $6,000 | $6,000 | $24,250 | $47,000 |
How you pay the costs changes the picture. Paying them out of pocket can reduce the amount you have for the down payment.
A 2021 study found nearly 15 percent of lower income homebuyers had closing costs exceeding their down payment.
Discount points are another line to price out. In 2022, the median discount points paid were $2,370, up from $1,225 in 2021.
Approval answers one question: what will a lender lend? Comfort answers another: what leaves room for groceries, repairs, and savings? Work through it in order:

| Comfort level | Housing payment | Share of take-home | Left after housing | Left after utilities and maintenance |
|---|---|---|---|---|
| Conservative | $1,867 | about 35% | $3,433 | $2,883 |
| Moderate | $2,400 | about 45% | $2,900 | $2,350 |
| Aggressive | $3,000 | about 57% | $2,300 | $1,750 |
The aggressive row leaves the least room for everything else, and unexpected repairs come out of that same cushion. If you want more breathing room, consider aiming for the moderate or conservative row.

In this article the 28/36 ratio is an illustrative assumption. Ask each lender which ratios it uses for your loan, and don't treat the highest approved ratio as a comfortable target.
The table above shows prices at 3.5% and 5% down under stated assumptions, so the monthly math can work. Mortgage insurance is typically required with less than 20% down, and you still need cash for closing costs.
Mortgage insurance is typically required if your down payment is less than 20 percent of the home's price. Your Loan Estimate will show what it costs for your loan.
Paying closing costs out of pocket can reduce your down payment. Compare your options on each lender's Loan Estimate, and consider asking a loan officer how each choice would change your costs.
Borrowers are advised to request multiple Loan Estimates from different lenders to compare and choose the right loan. Lining them up side by side makes differences in rate and fees easy to see.
