Longmont Rental
Market Intelligence

Market Overview

Longmont sits at the intersection of Boulder County's high cost of living and the more affordable northern Front Range corridor. With 9 scored properties and an average 8-signal vacancy monitoring, Longmont is the lowest-scoring city in our metro coverage by average index. This is not alarming on its own, but it indicates that Longmont landlords face slightly more competitive conditions than their counterparts in Thornton, Denver, or Arvada.

Average rents of $1,892 are the second-lowest among our tracked cities (only Greeley is lower at $1,562), and the 42-day average time to lease is among the highest. Longmont's rental market reflects a city where many tenants are price-sensitive workers who commute to Boulder or the Denver metro for employment. When rents push too high relative to income, these tenants look to Greeley, Frederick, or Firestone instead.

Longmont's proximity to Boulder creates an interesting dynamic. Properties that can market themselves as "Boulder area" while offering Longmont pricing tend to perform better. But landlords who try to charge Boulder rents in Longmont ZIP codes get punished with extended vacancy.

ZIP Code Breakdown

Longmont's three ZIP codes show subtle but meaningful differences in vacancy risk.

Key Findings

• 80504 is the weakest ZIP in the metro. Covering southeast Longmont and parts of the Mead corridor, 80504 scores just 61. This area has seen significant new construction that competes directly with existing rentals, putting downward pressure on older housing stock that cannot match the amenities of newer builds.
• Longmont's 42-day lease-up is a red flag. Among all 8 tracked cities, only Golden (58 days) takes longer to fill a vacancy. The combination of lower rents and longer lease-up time means Longmont landlords face a double hit: less income per unit and more lost revenue during turnover. A single vacancy month at $1,892 costs 8.3% of annual gross.
• Price sensitivity is acute here. Longmont tenants are the most responsive to rent increases in our dataset. Our tenant search simulation shows that Longmont listings priced 5% above market see 2x the days on market compared to properties priced at or below the Rentometer median. In Denver or Thornton, that same 5% premium adds far less friction.
