Local Market Data
Washington County Apartment Market
Figures gathered October 2026 from public market data.
If you plan to sell commercial property in Washington County, OR, start with the renter base: 92,176 households, 39.2% of all occupied homes, rent rather than own, per the Census Bureau's 2020-2024 American Community Survey. That share tops the 36.7% Oregon figure. Median gross rent reached $1,849, up 36.1% from the 2015-2019 survey, well above the $1,525 statewide median rent figure.
Apartment stock is concentrated in a handful of cities. Hillsboro and Beaverton alone hold roughly two-thirds of the county's 92,176 renter households, and both host major employers that keep demand steady. Rental vacancy sits at 4.1%, tighter than the 4.2% state rate, so lease-up risk is modest. The sections below cover rents, city-by-city comparisons and tax rules for Washington County.

Property taxes and assessment in Washington County
Oregon caps most annual assessment growth under Measure 50. A property's maximum assessed value cannot rise more than 3% a year unless it adds new construction, an improvement, or is split through a partition, per the Oregon Department of Revenue. Taxable value is the lesser of that capped figure and real market value.
Washington County assessors appraise real market value as of January 1 each year, and tax rates are expressed per $1,000 of assessed value, combining the county's permanent rate with city, school and special-district levies. Measure 5 limits school rates to $5 and general government rates to $10 per $1,000 of real market value, compressing any excess. Owners can appeal real market value to the county Property Value Appeals Board by December 31.
Washington County is also one of the few Oregon counties with a local real estate transfer tax, because Oregon Revised Statutes Section 306.815 bars new local transfer taxes but grandfathers any ordinance already in effect on March 31, 1997. Confirm the current rate and any exemptions with the Washington County Department of Assessment and Taxation before closing.
What this means if you sell in Washington County
When you sell commercial property in Washington County, OR, you sell into a renter-heavy market. Renters hold 39.2% of households, and median gross rent has climbed 36.1% since the 2015-2019 survey. Rental vacancy of 4.1% means most buyers underwrite near-full occupancy rather than lease-up risk.
Taxes and transfer rules take more diligence here than in many Oregon counties. Washington County's grandfathered transfer tax and Measure 50's assessment cap both affect net proceeds, and buyers will factor Oregon's statewide rent-increase limit under ORS 90.323 into their rent projections rather than assuming free pricing.
As a multifamily buyer in Washington County, we review 5+ unit buildings from Hillsboro to Forest Grove as they stand today. Selling an apartment building in Washington County goes faster with a current rent roll, a T-12 and the latest tax statement in hand, and we will price the building on those numbers.
