Where Caldwell's Apartment Demand Comes From

Rental demand in Caldwell comes from 5,814 renter households, which is 27% of occupied housing (ACS 2020–2024). Renter households dropped 5.6% between the 2015–2019 and 2020–2024 surveys. We treat that as a caution flag and look closely at occupancy in any building we consider here.

Median household income in Caldwell, ID is $73,058, up 49% over five years. Resident employment rose 36.4% and the unemployment rate was 5% in the latest survey. Rent and income have moved at a similar pace (44% and 49%), so affordability hasn't shifted much.

Caldwell leans toward ownership. Apartment buildings compete with single-family rentals for tenants, so we look closely at how a property's rents compare with nearby rental houses.

Rents, Vacancy And Supply In Caldwell

Median gross rent in Caldwell, ID is $1,264 a month, up 44% from $878 in the 2015–2019 survey (U.S. Census ACS 2020–2024). Few markets grew rent faster over the period. We still underwrite slower growth from here, because rent spikes tend to cool once new supply catches up.

Rental vacancy is 5.6%, within the normal range for a balanced market. Census vacancy estimates for smaller places carry wide margins of error, so we check them against current local listings. 49.6% of renters spend 30% or more of their income on housing. That is close to the national picture, where roughly half of renters do, so rent increases need to track local wage growth.

About 6.1% of homes in Caldwell are in buildings with 5 or more units, roughly 1,357 homes. That count rose 15.4% over five years, a sign of meaningful new apartment construction that newer buildings will compete with. The median home was built in 2003, so the housing stock is relatively new. Value-add plans here lean more on management and amenities than on heavy renovation. For comparison, HUD's fiscal year 2027 Fair Market Rent for a two-bedroom unit in the Boise City, ID HUD Metro FMR Area is $1,540 a month.

Caldwell By The Numbers

Out of 14 Idaho cities in our data, Caldwell comes in 8th for median gross rent, 11th for renter share and 7th for five-year rent growth. Its rents fall in the middle of the pack. Compared with the 2015–2019 survey, Caldwell now has about 11,629 more residents, 345 fewer renter households and 181 more homes in buildings with 5 or more units. With fewer renter households than before, a building has to win tenants from competitors rather than from new demand.

Caldwell And Nearby Markets Side By Side

Caldwell's median gross rent of $1,264 is above the Idaho median of $1,238, and its renter share is 27% compared with 27.9% statewide.

Caldwell Rent Affordability In Dollars

The median rent in Caldwell works out to $15,168 a year, about 20.8% of the median household income of $73,058. Under the common 30% guideline, a household needs about $50,600 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 $386 a month ($4,632 a year), while median household income rose $24,026 a year. Income has outpaced rent, which means tenants have a bit more room in their budgets than they did five years ago. HUD's FY2027 Fair Market Rent for a two-bedroom unit, $1,540, is 21.8% 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 Caldwell Apartment Building

In Caldwell 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 Caldwell

Before you invest in an apartment syndication in Caldwell, with us or anyone else, the local data points to a few questions worth asking.

• What vacancy does the plan assume? Rental vacancy in Caldwell is 5.6%. A plan that assumes much lower vacancy than the market should explain why.
• What rent growth is underwritten? Rents here rose 44% 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 Caldwell was built in 2003, 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 Caldwell rose 15.4% 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 Caldwell 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.

Expect your money to be tied up for years, with no easy way to sell your share early, and remember that any investment can lose money. Most deals are open only to accredited investors under Rule 506(b) or 506(c). See investing with Skyline Capital for how we work with limited partners.
