Local Market Data
Washington Apartment Market
Figures gathered October 2026 from public market data.
Owners weighing whether to sell commercial property in Washington can start with two numbers buyers already know: a $1,760 statewide median gross rent and 4.5% rental vacancy, per the Census Bureau's 2020-2024 American Community Survey. Renters fill 36.2% of occupied Washington homes, and 22.2% of all Washington housing units sit in buildings with five or more units, so larger apartment stock is a real share of the market, not a niche.
County figures swing well past that statewide line. King County carries a $2,092 median gross rent and 5.3% rental vacancy, while Spokane County rents run closer to $1,283 and Clark County vacancy sits at 3.6%. The sections below cover Washington rents, five-year trends, a six-county comparison, and the state's landlord and tax rules, so a Washington owner can see roughly how a buyer will price a building before an offer lands.
King County scale and rent
King County posts a $2,092 median gross rent and 44.6% renter share, the highest of Washington's six covered counties, per ACS table B25064.Statewide income growth
Washington median household income rose 33.0%, from $73,775 to $98,141, between the 2015-2019 and 2020-2024 ACS periods, per table B19013.Larger-building stock expansion
Units in Washington buildings with five or more units grew 14.6% to 732,621 between the two ACS periods, per Census table B25024.The Washington rental market at a glance
Washington had 1,110,043 renter households in the Census Bureau's 2020-2024 American Community Survey, or 36.2% of 3,064,820 occupied homes. Owners hold the other 63.8%. Larger apartment stock is a meaningful part of Washington's housing supply: 732,621 Washington housing units, 22.2% of the 3,306,620 total, sit in buildings of five or more units, per ACS table B25024.
Washington rental vacancy stood at 4.5% in the 2020-2024 DP04 housing profile, tight next to many other states. Statewide median household income was $98,141, so the $1,760 median gross rent equals about 21.5% of a typical household's gross income. Renters themselves feel more strain than that average implies: 49.9% of Washington renter households paid 30% or more of income on rent, per ACS table B25070.
Five-year trends in Washington
Washington median gross rent rose 39.9% between the 2015-2019 and 2020-2024 ACS periods, climbing from $1,258 to $1,760 a month. Median household income grew 33.0% over the same span, from $73,775 to $98,141. Rent growth therefore outpaced income growth by 6.9 percentage points statewide.
Washington gained 54,886 renter households between the two periods, a 5.2% increase. Units in buildings of five or more units rose 14.6%, adding 93,389 units statewide. The larger-building stock expanded nearly three times faster, in percentage terms, than the renter base using it.
County-level growth varied widely across Washington. Pierce County rents climbed 44.5% and Thurston County rents 42.5% between the two ACS periods, both ahead of the 39.9% statewide rate. Clark County's renter households grew fastest of the six, up 14.3%, while Thurston County's renter base rose only 0.9%.
Washington county comparison
Median gross rent across the six Washington counties covered here ranges from $1,283 in Spokane County to $2,092 in King County. Rental vacancy runs from 3.6% in Clark County to 5.3% in King County, each figure drawn from that county's 2020-2024 ACS data.
| County | Median gross rent | Renter share | Share of units in 5+ buildings | Rental vacancy |
|---|---|---|---|---|
| King County | $2,092 | 44.6% | 37.6% | 5.3% |
| Pierce County | $1,806 | 35.3% | 18.2% | 4.1% |
| Snohomish County | $1,949 | 31.8% | 20.7% | 4.0% |
| Spokane County | $1,283 | 35.5% | 20.4% | 3.9% |
| Clark County | $1,748 | 33.6% | 17.5% | 3.6% |
| Thurston County | $1,736 | 32.3% | 14.7% | 4.0% |
King County leads this group on both renter share, at 44.6%, and units in five-plus buildings, at 37.6%. Snohomish County posts the lowest renter share of the six, at 31.8%, even though its 4.0% vacancy rate sits in the middle of the pack.
Washington landlord, tax and transfer rules
Washington capped most annual rent increases statewide in 2025 under House Bill 1217, limiting them to 7% plus inflation or 10%, whichever is lower. Washington cities are separately barred from adopting their own rent-control ordinances under RCW 35.21.830, so the 2025 statewide cap is now the operative limit for a Washington apartment owner.
Washington sets no statutory dollar cap on security deposits, but RCW 59.18.280 requires the landlord to return a deposit, with an itemized statement of any deductions, within 21 days after the tenancy ends. RCW 59.18.260 requires a signed move-in checklist before any deposit can be withheld for anything beyond ordinary wear.
Washington's statewide just-cause eviction law, RCW 59.18.650, requires a landlord to cite one of a defined list of reasons before ending a periodic tenancy or declining to renew a lease; a plain no-cause termination is not available.
County assessors value Washington real property, including apartment buildings, at 100% of true and fair market value each year under RCW 84.40.030. Washington also charges a real estate excise tax on sale under RCW 82.45, at graduated state rates plus a local add-on, with no carve-out for multifamily property.
What this means if you sell in Washington
Owners who sell commercial property in Washington get priced on rent rolls, vacancy, and the next tax bill like anywhere else, but the 2025 rent cap now also shapes how a buyer models future income. A building in Clark County, at 3.6% vacancy, reads very differently to a buyer than one in King County at 5.3%.
Taxes are worth a close look too. Because Washington values property at full market value every year under RCW 84.40.030 and adds a real estate excise tax under RCW 82.45 at closing, we model both the coming assessment and the closing cost before setting a number.
We review Washington buildings of five or more units across the six counties above and the rest of Washington. Send the rent roll and the latest Washington tax statement, and we will set the property against these county figures.

Washington Seller FAQ
What should I check before I sell commercial property in Washington?
Start with rent and vacancy, since buyers do. Washington median gross rent was $1,760 a month and rental vacancy 4.5% in the Census Bureau's 2020-2024 ACS. Then check the assessor's current market-value assessment, since RCW 84.40.030 values property at 100% of market value each year.
Does Washington charge a transfer tax when an apartment building sells?
Yes. Washington imposes a real estate excise tax under RCW 82.45, with graduated state rates plus a local component, due at closing on the sale price. There is no carve-out for commercial or multifamily property, so sellers should budget for it before setting an asking price.
Can Washington landlords still raise rents freely?
Not as freely as before. House Bill 1217, effective in 2025, caps most annual rent increases statewide at 7% plus inflation or 10%, whichever is lower. Washington cities cannot impose their own rent-control ordinances under RCW 35.21.830, so the statewide cap now controls.
Which Washington county has the tightest rental vacancy?
Clark County, at 3.6% in the 2020-2024 ACS, is the tightest of the six Washington counties covered here, followed closely by Spokane County at 3.9%. King County runs loosest among the six, at 5.3%, despite also posting the highest median gross rent.
How do I sell commercial property in Washington?
Send us the address, unit count, and a rent roll if you have one. We review Washington apartment buildings of 5+ units against our buy box and give clear feedback, typically within 48 hours.
Do you buy apartment buildings everywhere in Washington?
Yes. We evaluate multifamily properties statewide, including Seattle, Spokane, Tacoma, Vancouver, Tri-Cities, Bothell, Burien, Lacey, smaller cities, and suburban markets. Every property is reviewed on its own fundamentals.
What types of Washington multifamily properties do you buy?
Apartment buildings and income-producing residential properties with 5 or more units — stabilized, value-add, mismanaged, or distressed. Our sweet spot is 15–25 units, and we review larger communities with capital partners.
Is it possible to sell rental property in Washington without evicting tenants?
It is. We buy apartment buildings occupied, and tenants stay on their current leases. Skyline Capital Investments is a commercial real estate buyer of 5+ unit buildings, so occupied properties are the norm for us.
What do I need to sell my apartment building in Washington?
An address and unit count are enough to start. A current rent roll and trailing twelve-month statement let us move to a written offer faster.
Do I need to make repairs before selling?
No. We underwrite properties as they are today, including deferred maintenance and vacancy.
