Home Affordability in Washington
Affordability in Washington is driven by four variables working together: property tax rate of 1.04%, average homeowners insurance of $1,800, average mortgage rate of 7.46%, and median home price of $740,000. When the DTI calculation runs at the standard 35/43 tier on a $120,000 household income, the maximum purchasing power lands in a specific range determined by all four.
The 28/36 conservative rule gives more cushion but smaller purchasing power. The 43/50 aggressive tier expands purchasing power but pushes borrowers to the edge of approval. Lenders in Washington typically accept the middle 35/43 tier for automated approval — the same as the national guideline because DTI caps are set by federal qualified mortgage rules, not state law.

Frequently asked questions
How much house can I afford in Washington?
On a $120,000 annual income in Washington, the standard 35/43 DTI guideline allows total monthly debt payments up to $4,035 and housing costs up to $3,284. At Washington's 7.46% average rate with 20% down, that translates to a maximum home price in the $666,000 to $962,000 range depending on the DTI tier selected.
What is the 28/36 rule for Washington?
The 28/36 rule says housing costs should stay under 28% of gross monthly income and total debt under 36%. On a $120,000 annual income ($9,383/month), that means housing under $2,627 and total debt under $3,378. Lenders use 28/36 as the conservative tier; FHA and VA loans allow up to 43% and 50% respectively.
How does Washington's property tax affect affordability?
Washington's 1.04% effective rate directly reduces your maximum home price. On a $120,000 income, every 0.1% increase in the effective tax rate reduces purchasing power by approximately $8,000 to $12,000. In Washington, the median home carries roughly $7,696 in annual property taxes — a monthly escrow of about $641.
Does down payment affect affordability in Washington?
Yes, materially. Increasing down payment from 10% to 20% on a $740,000 Washington home adds $74,000 in cash but eliminates PMI (roughly $200 to $350/month), which increases the loan amount you can qualify for. Lenders also offer better rates at 80% LTV, further expanding purchasing power.
What DTI do I need to qualify in Washington?
Conventional loans in Washington typically require back-end DTI at or below 43% for automated approval, with 50% maximum under manual underwriting with compensating factors. FHA allows 43% automated and up to 50% manually. VA allows up to 50% in most cases. The best rates unlock at DTI below 36%, so buyers with lower DTI qualify for larger loans at better pricing.
How much income do I need for a median Washington home?
For the median Washington home priced at $740,000 with 20% down at 7.46%, the estimated PITI runs approximately $4,662/month. To stay under the 28% front-end rule, you would need gross monthly income of at least $16,649.
