Homestead exemption
Washington has no ad-valorem homestead exemption that reduces annual property tax bills for the general homeowner (its 'homestead exemption' — currently the greater of $125,000 or the county median home value, under RCW 6.13 — is a bankruptcy/creditor-protection exemption, unrelated to property tax). For actual property tax relief, the Department of Revenue's Property Tax Exemption Program for Senior Citizens, People Retired Due to Disability, and Veterans with Disabilities freezes the home's assessed value and exempts qualifying low-income (county-varying, roughly under $84,000-$90,000+ depending on county) senior/disabled/disabled-veteran homeowners from regular and/or excess levies; a separate deferral program lets qualifying seniors/disabled homeowners postpone paying property taxes.

First-time buyer / down payment assistance programs

  • WSHFC Home Advantage

    Washington State Housing Finance Commission's primary 30-year fixed-rate first mortgage program, available statewide to eligible homebuyers (first-time-buyer requirement waived in targeted areas and for some borrower categories); typically paired with Home Advantage down payment assistance (a 0%-interest deferred second mortgage of 3%-5% of the first-mortgage amount).

Closing Costs in Washington: What You'll Actually Pay

  • Washington's biggest closing-table tax, the real estate excise tax, costs $6,798 on the $617,990 statewide median sale price and is customarily paid by the seller, not the buyer.
  • Buyer closing costs in Washington run about 2% to 3% of the purchase price, which is $12,360 to $18,540 at the median, with a midpoint near $15,450.
  • The excise tax is graduated by price, not flat: 1.10% on the portion up to $750,000, 1.28% from $750,001 to $1,525,000, 2.75% to $3,025,000, and 3.00% above that.

The scariest number in a Washington transaction is the real estate excise tax. On the statewide median sale price of $617,990, the state's base 1.10% rate comes to $6,798, before your city or county adds its own portion.

Here's the part that changes how you budget: the excise tax is customarily paid by the seller. It appears on nearly every settlement statement in the state, it's genuinely large, and in a normal transaction it isn't yours.

That leaves buyers with a bill that's modest as a percentage — roughly 2% to 3% — attached to some of the highest home prices in the country. Two percent of $617,990 is $12,360; where the median is $250,000, a buyer paying twice that rate still writes a smaller check. The problem isn't the percentage, it's the multiplier.

The real work is knowing which side of the ledger each item lands on, and what the graduated tax does above the median. For how the fees work, start with our line-by-line breakdown of what's actually on a closing statement.

A note before you start: this is general education, not financial, legal, or tax advice. Every figure below is a statewide number from CalculatorByState's sourced dataset, and your county, city, lender, escrow company, and contract will all move the total. Local excise rates and escrow fees vary by jurisdiction, and excise brackets apply to the specific selling price on your contract. Your Loan Estimate and Closing Disclosure are the authoritative documents. Use this to sanity-check them, not to replace them.
