Where Boise's Apartment Demand Comes From

Boise has 37,268 renter households, and 36.8% of the city's households rent, well above the Idaho share of 27.9% (U.S. Census ACS 2020–2024). The city grew 4.9% in five years to 237,242 people, and the number of employed residents rose 8.4%. Median gross rent in Boise is $1,446 a month, up 51.1% from $957 in the 2015–2019 survey. Incomes rose too, with median household income up 39.8% to $83,904, but 49% of renters still spend 30% or more of their income on housing.

Health care, the state capital and the university anchor the job base. St. Luke's Regional Medical Center was the Boise metro's largest employer in 2025 with more than 10,000 workers, according to the Idaho Department of Labor, followed by St. Alphonsus Health System, Boise State University, Micron and the Meridian school district, each with 5,000 to 7,499. Albertsons, Walmart, the Boise School District and the City of Boise each employed 2,500 to 4,999. HUD's 2024 market analysis counted 13,350 State of Idaho employees, the largest single employer in the area. Covered employment across the metro rose about 4.1% from 2024 to 2025.

Boise State adds a steady student renter pool. HUD estimated about 18,150 full-time-equivalent students in 2024, with roughly 13,950 living off campus, mostly in the 7,975 or so private apartments near the university. For owners, that mix of hospital, government and university jobs is less cyclical than the region's tech and construction work.

Micron is the biggest swing factor. The chipmaker is building two memory fabs at its Southeast Boise headquarters, a project it now values at about $50 billion. As of February 2026 the first fab was under construction and expected to be finished in 2026, with first chip output in 2027, and ground was being prepared for the second. Micron estimates about 17,000 jobs in Idaho tied mostly to the project, including 3,500 direct hires. Reporting in 2024 put peak construction employment on the site at about 3,700 workers. That adds two waves of renters: trades workers now, and engineers and technicians as production ramps. Southeast Boise, near the campus and the airport, is where that demand lands first.

Boise's Supply Wave And The Rent Reset

The Boise area built heavily after 2020 and is still absorbing it. HUD put metro apartment vacancy at 11.1% at the end of 2023, with about 4,200 units under construction and average rent down 2% to $1,515. CoStar reported vacancy at 8.8% and falling in September 2025, with new supply expected to taper. CBRE put metro occupancy at 94.3% in the fourth quarter of 2025, with an average effective rent of $1,637 that was flat for the quarter, 1,713 units delivered in that quarter and only 597 units still under construction at year end. In January 2026 CoStar described rents as relatively flat in recent quarters even as vacancy kept falling. Listing data has since turned up: RentCafe put the average Boise apartment at $1,806 a month in September 2026, up 6.3% from $1,700 a year earlier. Listing averages and broker effective rents measure different things, so read them as direction, not a single number. At the end of 2023, nearly half of the units under construction were in the Meridian area west of Boise, per HUD, rather than in the city itself.

The Census shows a tighter picture inside city limits. Boise has 18,127 homes in buildings with five or more units, only 17.1% of its housing stock, though that count rose 13.9% in five years. The Census rental vacancy rate is 3.5%. That figure covers every rental, including houses and duplexes, so it is lower than broker vacancy for large communities, which includes buildings still in lease-up. The HUD fiscal 2027 fair market rent for a two-bedroom in the Boise City metro area is $1,540, a little above the city's Census median. The median Boise home was built in 1986.

For a buyer, the pipeline has shrunk to a fraction of its 2023 size, which should help occupancy at existing buildings. Rents were flat in late 2025, so apartment syndications in Boise should be underwritten on occupancy and expense control more than on a quick return to fast rent growth.

Boise By The Numbers

We track 14 Idaho cities. Boise places 6th for median gross rent, 4th for renter share and 3rd for five-year rent growth. Its rents fall in the middle of the pack. Compared with the 2015–2019 survey, Boise now has about 11,127 more residents, 1,433 more renter households and 2,212 more homes in buildings with 5 or more units. New homes in 5+ unit buildings outpaced the growth in renter households, so newer buildings are competing for tenants and older ones may need to offer more to keep them.

Boise Compared With Ada County

Boise's median gross rent of $1,446 is above the Idaho median of $1,238, and its renter share is 36.8% compared with 27.9% statewide.

Boise Rent Affordability In Dollars

The median rent in Boise works out to $17,352 a year, about 20.7% of the median household income of $83,904. Under the common 30% guideline, a household needs about $57,800 a year to cover that rent comfortably. That's a heavier load than the Idaho average of 19.1%. 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 $489 a month ($5,868 a year), while median household income rose $23,887 a year. Rent has outpaced income, so we are careful about how much further a business plan pushes rents on renewal. HUD's FY2027 Fair Market Rent for a two-bedroom unit, $1,540, is 6.5% 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 Boise Apartment Building

In Boise 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.

Property taxes are a big line item for any Idaho apartment building. We estimate the tax bill as it will be after the purchase, because a sale can trigger a reassessment in many places. Idaho has no statewide rent control law, though local rules on notices, fees and deposits still apply. Insurance quotes in Idaho 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 Boise

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

• What vacancy does the plan assume? Rental vacancy in Boise is 3.5%. A plan that assumes much lower vacancy than the market should explain why.
• What rent growth is underwritten? Rents here rose 51.1% 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 Boise was built in 1986, and even newer buildings need money set aside for roofs, HVAC and appliances.
• How will the building compete with new supply? Homes in 5+ unit buildings in Boise rose 13.9% over five years, so newer properties are part of the competition.
• 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 Boise 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.
