How much is a mortgage payment in Washington?

For a typical $400,000 home in Washington with a 20% down payment ($80,000) on a 30-year loan at 6.47%, the full monthly payment works out to about $2,412. That breaks down as $2,016 in principal and interest, $250 in property tax and $146 in homeowners insurance — so taxes and insurance add roughly $396 a month on top of the loan itself.

In Washington, property tax is the bigger of those two costs. The calculator above uses Washington's real figures by default, but every input is editable — drop in your own price, down payment, rate and HOA for an exact number, and add a loan type (FHA, VA or USDA) if you're not putting 20% down.

Washington property tax and home insurance

Washington's average effective property tax rate is 0.75% of a home's value — the 30th highest of the 50 states and DC (the 22nd lowest). On a $400,000 home that's about $3,000 a year, or $250 a month, escrowed into your payment. Property tax is the part of a mortgage that varies most from state to state, which is why a national calculator can be well off for Washington.

Average homeowners insurance in Washington runs about $1,753 a year for $300k of coverage — $790 below the US average of $2,543, the 38th highest in the country. That low premium keeps Washington payments below many other states at the same price.

Washington mortgage payment by home price

Because Washington's tax rate and insurance are fixed shares of the cost, the monthly payment scales with the price. With 20% down at 6.47%:

$300,000 home → about $1,846/mo · $400,000 home → about $2,412/mo · $500,000 home → about $2,979/mo (all including Washington tax and insurance).

Putting less than 20% down adds private mortgage insurance (PMI) until you reach 20% equity, and a lower rate or longer search for insurance can meaningfully cut the Washington figure. Use the inputs above to model your own scenario and see the amortization schedule.

What's included in a Washington mortgage payment (PITI)

A mortgage payment has four parts, often shortened to PITI: Principal, Interest, Taxes and Insurance — plus PMI if you put down under 20% and any HOA dues. In Washington, principal and interest on a $320,000 loan come to $2,016, then Washington's property tax ($250) and insurance ($146) are collected monthly into an escrow account and paid on your behalf.

This calculator computes all of PITI for Washington, shows a full amortization schedule, and estimates how much an extra monthly payment or biweekly schedule would save you in interest over the life of the loan.
