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.
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.
Why include Thurston County?
Thurston County captures Olympia, Lacey, Tumwater, and the south Puget Sound commute market.
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.
