Washington Mortgage Calculator - Monthly Payment with Taxes, PMI & Insurance
Washington property tax is budget-based and local. This state page uses a broad local property-tax planning estimate and a baseline state real estate excise tax estimate. County pages override property-tax estimates for the largest Washington mortgage markets. On a $400,000 Washington planning example with 20% down at 6.5% for 30 years, principal and interest are about $2,023; at ~0.95% statewide property-tax planning rate, tax escrow is about $317/mo, for estimated PITI near $2,440 before PMI. Washington has no state income tax, but overlapping local levies and the real-estate excise tax still shape monthly escrow and cash to close.

Frequently Asked Questions
Does Washington have one statewide property tax rate?
No. Washington property taxes depend on local levy districts, including schools, county, city, fire, and other districts. Use this state mortgage calculator to combine that assumption with principal, interest, insurance, and PMI, then drill into county or city pages when you have a specific address.
What Washington transfer tax is modeled?
The state page uses a baseline Washington real estate excise tax estimate. Actual REET can vary by sale price tier and local add-ons. Use this state mortgage calculator to combine that assumption with principal, interest, insurance, and PMI, then drill into county or city pages when you have a specific address.
What is a sample Washington PITI on $400,000?
With 20% down at 6.5% for 30 years, principal and interest are about $2,023. At ~0.95% statewide property-tax planning rate, monthly escrow is about $317; with $100 insurance, estimated PITI is about $2,440 without PMI. Drill into county or city calculators for address-level millage.
Does this mortgage calculator include taxes and insurance?
Yes. This calculator estimates your full monthly housing payment by combining principal and interest with property taxes, homeowners insurance, and PMI when your down payment is below 20%. The result reflects a PITI-style payment rather than principal and interest alone, which helps you compare homes and loan scenarios more realistically before talking to a lender.
When does PMI apply on a mortgage?
Private Mortgage Insurance (PMI) typically applies when your loan-to-value ratio exceeds 80%, meaning your down payment is less than 20% of the purchase price. PMI is usually added to the monthly payment until you reach sufficient equity. This calculator includes PMI in the estimate when your inputs trigger it, so you can see how a smaller down payment affects affordability.
