Who Rents In Renton, And Why

Renton is a renter's city by King County suburban standards. The Census counts 18,566 renter households, 45.6% of all households (U.S. Census ACS 2020–2024), against 36.2% for Washington as a whole. Median gross rent is $1,998 a month, up 29.5% from $1,543 in the 2015–2019 survey, and well above the state median of $1,760. Median household income rose almost as fast, by 29.2% to $100,432, yet 53.9% of renters still spend 30% or more of their income on housing. The city's population is 105,317, up 3.8% in five years.

Boeing is the reason Renton looks the way it does. Every 737 is assembled at the Renton plant on the south shore of Lake Washington, and in June 2026 Boeing said its three Renton lines were moving from 42 to 47 airplanes a month that summer. A fourth line, the North Line, was scheduled to start in Everett in July 2026, so future growth in 737 output will not all land in Renton. A 2023 profile by 425 Business listed Boeing, Valley Medical Center, Kaiser Permanente, the Renton School District and PACCAR as the city's largest employers. Valley Medical Center sits on the city's south side, UW Medicine leased former FAA space on Lind Avenue SW for lab work, and in 2022 the Seattle Sounders announced a training center with office space at Longacres on former Boeing land.

Location adds a second layer of demand. Renton sits where I-405 meets SR 167, between Bellevue and the Kent Valley warehouses, so many tenants work outside the city and choose Renton for rents below the Eastside. That mix of factory, hospital and commuter tenants keeps the renter base wide. The risk for owners is concentration: when Boeing slows production, as it did after the 737 MAX groundings, Renton feels it first.

Renton's Apartment Pipeline And Rents

Supply in Renton has come in steady pieces rather than one big wave. Sunset Terrace, 211 units at 2715 Sunset Lane NE, received a temporary certificate of occupancy in July 2023 and was refinanced with a HUD loan in 2025. In June 2025 developers announced Astra, a 275-unit mixed-income building at 2950 NE 11th Street that replaces an old strip mall, one half of a two-building project with the Solera complex. Larger plans exist on paper. In January 2023 Bay West Development filed for up to 1,179 apartments on the former Fry's Electronics site at 800 Garden Avenue North, with phases stretching to 2034, and we treat that as a proposal until it breaks ground.

The Census numbers point to a tight, aging stock. The city has 14,152 homes in buildings with five or more units, 33.3% of its housing. The Census shows that count down 6.3% over five years, which is hard to square with recent openings; ACS estimates carry a margin of error, and a change that size in a city this size can be sampling noise. The median home was built in 1988. Census rental vacancy is 4.6%, a figure that covers every rental, including houses and duplexes, so it reads lower than broker surveys of large communities.

Those broker surveys show a market that is firming, not racing. Kidder Mathews put South King County apartment vacancy at 6.2% in the second quarter of 2026, improving from earlier quarters, with an average rent of $1,821 and modest gains. HUD's fiscal 2027 two-bedroom Fair Market Rent for the Seattle-Bellevue area is $2,549.

For apartment syndications in Renton, the useful gap is between the older garden communities that make up much of the stock and the new mid-rise product near the Sunset corridor and The Landing. Older buildings that can be updated sit below new-construction rents but compete with them for the same Boeing and hospital workers. Buyers should underwrite against nearby recent leases and check how exposed the tenant base is to aerospace.

Where Renton Stands Among Its Peers

We track 44 Washington cities. Renton places 13th for median gross rent, 16th for renter share and 34th for five-year rent growth. Its rents fall in the middle of the pack. Put in counts rather than percentages, that is roughly 3,833 more residents, 188 fewer renter households and 952 fewer homes in buildings with 5 or more units than five years earlier. With fewer renter households than before, a building has to win tenants from competitors rather than from new demand.

Renton Compared With King County

Renton's median gross rent of $1,998 is above the Washington median of $1,760, and its renter share is 45.6% compared with 36.2% statewide.

Can Tenants Afford Renton Rents?

The median rent in Renton works out to $23,976 a year, about 23.9% of the median household income of $100,432. Under the common 30% guideline, a household needs about $79,900 a year to cover that rent comfortably. That's a heavier load than the Washington average of 21.5%. Renters usually earn less than the all-household median, so the real burden for tenants is higher than this simple ratio shows.

Since the 2015–2019 survey, the median rent rose $455 a month ($5,460 a year), while median household income rose $22,698 a year. The two have moved together, so affordability today looks much like it did five years ago. HUD's FY2027 Fair Market Rent for a two-bedroom unit, $2,549, is 27.6% above the median gross rent for all unit sizes. That gap matters for buildings that accept Housing Choice Vouchers, since local housing authorities base voucher payment standards on it.

What We Look For In A Renton Apartment Building

In Renton we focus on apartment buildings with 5 or more units. Some are stabilized and well run. Others have below-market rents or deferred maintenance that a better operator can fix. Either way, the deal has to make sense on current numbers.

Washington has no state income tax on wages, and property taxes are often one of the largest expenses for apartment owners. We estimate the tax bill as it will be after the purchase, because a sale can trigger a reassessment in many places. Washington adopted a statewide cap on annual rent increases in 2025 for most rental housing older than 12 years. Our rent-control guides explain how these rules work. Insurance quotes in Washington reflect wildfire risk, so we get a quote before we make an offer.

Given how fast rents rose here, we assume much slower rent growth going forward and make sure the deal still works if rents stay flat for a while.

Due Diligence For Apartment Syndications In Renton

Whoever the sponsor is, these are the questions we would want answered about any apartment syndication in Renton, based on the local numbers above.

• What vacancy does the plan assume? Rental vacancy in Renton is 4.6%. A plan that assumes much lower vacancy than the market should explain why.
• What rent growth is underwritten? Rents here rose 29.5% over five years. Ask whether the plan assumes that pace continues, and what happens to the deal if rents stay flat.
• How was the property tax bill estimated? A sale often triggers a reassessment, so the bill after purchase can be well above what the seller pays today.
• How big is the repair reserve? The median home in Renton was built in 1988, and even newer buildings need money set aside for roofs, HVAC and appliances.
• How will the building hold occupancy? Renter households in Renton fell 1%, so the plan should show how it keeps units full.
• How and when does capital come back? Ask what the plan is for a refinance or sale, and what happens if that takes longer than expected.

How Passive Investing In A Renton Apartment Syndication Works

A syndication splits the work from the capital. As general partner, Skyline sources and buys the building, sets the business plan and runs it with a property manager. Limited partners invest money, own part of the property and receive reports, but they don't manage anything day to day.

Syndications are long-term and illiquid, and capital usually stays committed for several years. Results are never certain. Most offerings are limited to accredited investors, and the rules depend on whether a deal uses Rule 506(b) or Rule 506(c). See investing with Skyline Capital for how we work with limited partners.
