Where Nampa's Renters Come From

Nampa is growing fast, but most of that growth has been owners. The city's population reached 110,319, up 17.4% in five years, and the number of employed residents rose 27.4% (U.S. Census ACS 2020–2024). Renters make up 29.8% of households, or 11,656 in all, a little above the 27.9% share for Idaho. The Census puts renter households 0.3% lower than five years earlier, which is hard to square with that much population growth. ACS estimates carry a margin of error, so read it as a flat renter count rather than a real decline.

The job base is wider than a typical commuter suburb. Amazon opened the Treasure Valley's first fulfillment center in Nampa in 2020. Food processing has deep roots here: Amalgamated Sugar has run a Nampa factory for more than a century, and Sorrento Lactalis and Materne, the maker of GoGo squeeZ, have both expanded local plants. Double R Trailers has been headquartered in Nampa since 2002, and Mission Aviation Fellowship, onsemi, Plexus, Woodgrain and Union Pacific all have operations in town. The Stow Company announced a $143 million, 550,000-square-foot closet and storage plant in the Midland Industrial Park in 2022, with about 236 jobs and an opening targeted for May 2023. Saint Alphonsus and St. Luke's both run medical centers in the city, and Northwest Nazarene University, the College of Western Idaho's Nampa campus and Boise State's West Campus add students and staff.

For apartment owners, the takeaway is a renter base made up largely of working households in manufacturing, logistics, health care and education. Median household income is $74,279, up 52.1% in five years, but 50.1% of renters still spend 30% or more of income on housing, so tenants here notice every rent increase.

New Supply And Rents In Nampa

Rents in Nampa have climbed quickly. Median gross rent is $1,420 a month, up 53.5% from $925 in the 2015–2019 survey and well above the Idaho median of $1,238 (U.S. Census ACS 2020–2024). HUD's fiscal 2027 Fair Market Rent for a two-bedroom in the Boise City metro area, which includes Nampa, is $1,540 a month.

Large apartment buildings are a small part of the city. Only 7.2% of Nampa's homes, about 2,900, sit in buildings with 5 or more units, though that count grew 16.0% in five years. The housing stock is young, with a median year built of 2000, and much of it is single-family subdivisions. Census rental vacancy is 3.9%. That figure covers every rental, including houses and duplexes, so it usually runs below the vacancy that brokers report for large managed communities.

The wider Treasure Valley went through a heavy round of apartment deliveries. Lee & Associates reported that metro vacancy peaked in late 2024 and was falling through 2025, as renters absorbed more units than were delivered, with rent growth near flat. Nampa owners still compete with lease-ups in Meridian and Boise, so concessions at new properties across the valley matter even for an older Nampa building.

The bigger supply question is long term. A city plan for southwest Nampa, the mostly undeveloped land between Karcher Road and Lake Lowell Avenue, calls for high-density housing such as apartments around a mixed-use Midway/Lone Star district. The city has estimated it will need 16,940 more homes by 2040. For anyone weighing apartment syndications in Nampa, that pipeline is worth tracking, along with how much of the city's new rental supply arrives as build-to-rent houses and fourplexes rather than 5+ unit buildings.

Nampa By The Numbers

We track 14 Idaho cities. Nampa places 7th for median gross rent, 10th for renter share and 2nd for five-year rent growth. Its rents fall in the middle of the pack. Put in counts rather than percentages, that is roughly 16,367 more residents, 35 fewer renter households and 400 more 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.

How Nampa Compares With Nearby Markets

Nampa's median gross rent of $1,420 is above the Idaho median of $1,238, and its renter share is 29.8% compared with 27.9% statewide.

Rent Versus Income In Nampa

At $1,420 a month, the median Nampa rent adds up to $17,040 a year, or roughly 22.9% of what the median household earns. Under the common 30% guideline, a household needs about $56,800 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.

In dollars, Nampa rent climbed $495 a month over five years and household income climbed $25,443 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, $1,540, is 8.5% 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 Nampa Apartment Building

Our buy box in Nampa is the same one we use nationwide: 5+ unit apartment buildings, stabilized or in need of work, priced on today's rents. Then we test the property against the local data on this page and a full inspection of its major systems.

Property taxes are a big line item for any Idaho apartment building. We underwrite the tax bill after purchase, not the seller's current bill, since a sale often resets the assessment. 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.

After a stretch of fast rent growth, we keep rent assumptions modest and leave room for concessions if new supply opens nearby.

Evaluating Apartment Syndications In Nampa

The data on this page turns into a short checklist for evaluating an apartment syndication in Nampa.

• What vacancy does the plan assume? Rental vacancy in Nampa is 3.9%. A plan that assumes much lower vacancy than the market should explain why.
• What rent growth is underwritten? Rents here rose 53.5% 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 Nampa was built in 2000, 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 Nampa rose 16% 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 Nampa Apartment Syndication Works

Here's the short version. The general partner, in this case Skyline, finds an apartment building in Nampa, buys it with a loan and investor capital, and runs it. Limited partners supply part of that capital and hold an ownership share, without landlord duties or personal liability for the loan.

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.
