What Fills Longmont's Apartments

Longmont's renter base has grown faster than its population. The U.S. Census ACS 2020–2024 counts 15,823 renter households, 37.5% of all households, up 9.4% in five years, while the population rose 5.3% to 99,406. Colorado's renter share is 33.8%. Employed residents grew 9.5% and median household income rose 22.1% to $90,671. Even so, 60.7% of renter households spend 30% or more of income on housing, which tells you how far rents have run ahead of local pay.

The job base mixes public payrolls with technology and manufacturing. The city's 2020 annual financial report listed St. Vrain Valley Schools as the largest employer with 3,543 workers, followed by the City of Longmont at 1,625 and Seagate Technology at 1,430. Intrado, Longmont United Hospital, UCHealth Longs Peak Hospital, McLane Western, the Federal Aviation Administration, Circle Graphics and AveXis rounded out the top ten. Manufacturing was the largest industry by resident employment in 2022, and craft brewers such as Left Hand and Oskar Blues add to the city's identity. Amgen's 2015 campus closure is a reminder that single large employers can leave.

Location does the rest. State Highway 119 runs about 15 miles southwest to Boulder and 5 miles east to I-25, and U.S. 287 links Longmont to Loveland and Denver. That puts Boulder jobs and the I-25 corridor within a short drive for Longmont renters. Commuter rail is still far off: RTD's plans as of 2024 put a B Line extension to Longmont possibly in the early 2040s. For owners, demand rests on regional commuters as much as on local jobs, so access to SH 119 matters when you compare properties.

Apartment Supply And Rents In Longmont

Median gross rent in Longmont is $1,816 a month (U.S. Census ACS 2020–2024), up 35.5% from $1,340 in the 2015–2019 survey and above the Colorado median of $1,761. HUD's FY2027 two-bedroom Fair Market Rent for the Boulder metro is $2,033. The Census rental vacancy rate is 3.9%.

That low Census figure hides a building wave. The Census count of homes in buildings with five or more units jumped 30.6% in five years to 10,564, now 24.3% of the housing stock, and the median home was built in 1991. ACS estimates carry a margin of error, but the direction matches what brokers report. Matthews' Boulder market report put Longmont's vacancy for professionally managed apartments at 8.9% at the end of 2024. The gap exists because the Census counts every rental, including houses and duplexes, while brokers track large communities still leasing up new units. Listings on Redfin in fall 2026 showed several Longmont communities offering 6 to 12 weeks of free rent, a sign that landlords are still competing for tenants.

More supply is coming. Thompson Thrift's 324-unit Heritage on Hover was expected to finish by winter 2026. The Garrett Companies financed a 224-unit garden-style community at 245 Bountiful Avenue in June 2025, aiming for early 2027. McWhinney and Livmark broke ground on the 200-unit Mountain Brook Flats in December 2025, with leasing planned for 2027, and Wood Partners started site work on the 252-unit Alta Longmont on East Rogers Road in May 2026, targeting spring 2028. Together that's roughly 1,000 units.

For a buyer, this is a market to underwrite with concessions built in for the next two years. Investors studying apartment syndications in Longmont may find better pricing on stabilized 1990s and 2000s properties than on new lease-ups, but should test rent assumptions against the new supply nearby.

Where Longmont Stands Among Its Peers

Among the 28 Colorado cities we track, Longmont ranks 15th for median gross rent, 15th for renter share and 14th for five-year rent growth. Its rents fall in the middle of the pack. In raw numbers, Longmont has about 4,961 more residents, 1,360 more renter households and 2,475 more homes in buildings with 5 or more units than in the 2015–2019 survey. 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.

How Longmont Compares With Nearby Markets

Longmont's median gross rent of $1,816 is above the Colorado median of $1,761, and its renter share is 37.5% compared with 33.8% statewide.

Rent Versus Income In Longmont

At $1,816 a month, the median Longmont rent adds up to $21,792 a year, or roughly 24% of what the median household earns. Under the common 30% guideline, a household needs about $72,600 a year to cover that rent comfortably. That's a heavier load than the Colorado average of 22.1%. Renters usually earn less than the all-household median, so the real burden for tenants is higher than this simple ratio shows.

In dollars, Longmont rent climbed $476 a month over five years and household income climbed $16,411 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, $2,033, is 11.9% 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 Longmont Apartment Building

We look at buildings with 5 or more units in Longmont, from small walk-ups to larger garden-style communities, in stabilized or value-add condition. We compare in-place rents with nearby buildings, inspect roofs, plumbing and HVAC, and ask whether better management or targeted renovation can close the gap with the market.

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

Questions To Ask About An Apartment Syndication In Longmont

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

• What vacancy does the plan assume? Rental vacancy in Longmont is 3.9%. A plan that assumes much lower vacancy than the market should explain why.
• What rent growth is underwritten? Rents here rose 35.5% 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 Longmont was built in 1991, 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 Longmont rose 30.6% 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 Longmont Apartment Syndication Works

Two groups make an apartment syndication work. The sponsor, or general partner, handles the deal: finding the building, financing it and running the business plan. The limited partners are passive investors who contribute capital and share in the property's results under the offering's terms.

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.
