Figures gathered October 2026 from public market data.

Boulder County holds 52,108 renter households, a 38.0% share of its 137,008 occupied homes, per the Census Bureau's 2020-2024 American Community Survey. That share runs above Colorado's statewide renter rate of 33.8%, and Boulder city alone accounts for 45.0% of the county's renter households.
Median gross rent in Boulder County reached $1,966, up 31.5% from $1,495 in the 2015-2019 survey. Rental vacancy sits at a tight 4.0%, below the 5.1% Colorado rate, while 26.0% of Boulder County's housing stock sits in buildings of five or more units. Rents and vacancy both shift from one Boulder County city to the next, from Erie's $2,805 median to Longmont's tighter 3.9% vacancy.

Rents vary sharply across Boulder County's covered cities. Erie posts the highest median gross rent, at $2,805, despite the lowest renter share, 12.4%, among the four cities compared here.
| City | Median gross rent | Renter share | Share of units in 5+ buildings | Rental vacancy |
|---|---|---|---|---|
| Boulder | $2,018 | 52.8% | 43.0% | 4.3% |
| Longmont | $1,816 | 37.5% | 24.3% | 3.9% |
| Erie | $2,805 | 12.4% | 4.4% | 2.6% |
| Lafayette | $2,121 | 34.3% | 16.5% | 2.7% |
Boulder carries the densest apartment stock among the four, with 43.0% of its units in 5+ unit buildings, more than double Longmont's 24.3% share. Lafayette's 34.3% renter share and 2.7% vacancy rate point to a tighter rental market than the Boulder County average. Erie and Lafayette both post vacancy under 3.0%, while Boulder and Longmont run closer to the county-wide 4.0% figure.
Property taxes and assessment in Boulder County
Colorado assesses multifamily rental property in the same residential class as single-family homes, not as commercial property, according to the state Division of Property Taxation. For property tax years starting January 1, 2026, the statewide residential assessment rate is 6.8% for local government levies and 7.05% for school district levies.
Real property in Boulder County is revalued every odd-numbered year under the market approach, using comparable sales from a state-set window for the 2025-2026 cycle. Boulder County has not published a county-specific assessment adjustment beyond the statewide rate, so owners should confirm current mill levies with the Boulder County Assessor before pricing a sale. Colorado charges no real estate transfer tax; only a small state documentary fee applies to most deeds.
What this means if you sell in Boulder County
When you sell commercial property in Boulder County, CO, you are selling into a market where renters hold 38.0% of households and vacancy sits at a tight 4.0%. Buyers will weigh that tight vacancy against Boulder County's 59.9% rent-burden rate, since a stretched tenant base can limit how far rents can be pushed after closing.
Colorado's statewide rent control preemption, C.R.S. 38-12-301, keeps rent-setting a market decision rather than a local one, which simplifies underwriting across Boulder, Longmont, Erie and Lafayette alike. Deposit rules matter too: Colorado caps deposits at two months' rent and requires return within one month of lease end, or 60 days if the lease allows it.
As a multifamily buyer active in Boulder County, we review 5+ unit buildings from Boulder to Longmont as they stand today. Send a current rent roll and your latest tax statement, and we will price the property on those numbers.

Boulder County Seller FAQ
What should I know about taxes before I sell commercial property in Boulder County, CO?
Colorado taxes multifamily buildings as residential property, assessed at a statewide 6.8% local rate and 7.05% school rate for 2026. Boulder County applies its own mill levies on top of that rate, so confirm the current levy with the Boulder County Assessor before pricing a sale.
How high is rental vacancy in Boulder County?
Rental vacancy in Boulder County was 4.0% in the Census Bureau's 2020-2024 American Community Survey, below Colorado's 5.1% statewide rate. Within the county, Erie and Lafayette ran under 3.0% while Boulder posted 4.3%, so buyers weigh a building's own occupancy against those local rates.
How much have rents risen in Boulder County?
Median gross rent in Boulder County rose from $1,495 in the 2015-2019 survey to $1,966 in 2020-2024, a 31.5% gain. HUD's FY2027 two-bedroom Fair Market Rent for the Boulder, CO MSA is $2,033, running above the county's own median.
Does Boulder County have rent control?
No. C.R.S. 38-12-301 makes rent control on private residential housing a matter of statewide concern in Colorado, so no county or city, including Boulder County's cities, may enact a rent-control ordinance. Rent levels across Boulder, Longmont, Erie and Lafayette are set by the market.
How do I sell commercial property in Boulder County, CO?
Send the address, unit count, and any financials. We review Boulder County apartment buildings of 5+ units, give feedback typically within 48 hours, and follow with a written letter of intent if it fits.
Do you buy apartment buildings throughout Boulder County?
Yes. We evaluate multifamily properties across Boulder County, including Boulder, Longmont, Erie, and Lafayette, as well as smaller towns and unincorporated areas. Every property is reviewed on its own fundamentals.
What size Boulder County properties do you buy?
Apartment buildings and income-producing residential properties with 5 or more units. Our sweet spot is 15–25 units, and we review larger communities with capital partners.
Will you buy a property that needs work or has high vacancy?
Yes. We underwrite value-add, mismanaged, and distressed properties as they are today — no repairs or lease-up required before selling.
Is it possible to sell rental property in Boulder County without evicting tenants?
It is. We buy apartment buildings occupied, and tenants stay on their current leases. Skyline Capital Investments is a commercial real estate buyer of 5+ unit buildings, so occupied properties are the norm for us.
How fast can I sell my apartment building in Boulder County?
Most owners get clear feedback within 48 hours of sending the address, unit count, and a rent roll. Closing is typically set around your timeline, including extra time for a 1031 exchange.
How do property taxes factor into a Boulder County offer?
Property is assessed at the county level (the county seat is Boulder), within Colorado rules. Colorado reappraises property every odd-numbered year, and the legislature has adjusted residential assessment rates several times recently. We model the current rate and the next reappraisal when we prepare an offer.
