Market Intelligence & Opportunity
Ada County recorded 205 condo closings in 2015 and 190 in 2025. Over the same period, the median price of a condo that sold rose from $150,000 to $412,500. This contrast is central to understanding the segment: its price range evolved, yet condo sales did not grow into a steadily larger share of local transactions.
A small market with distinct peaks
Boise’s wider housing story gives this small category some scale. Ada County grew from 392,365 residents in the 2010 census to an estimated 546,141 in 2025, roughly 39%. During the most intense part of the housing boom, the Federal Housing Finance Agency reported 41.1% annual appreciation for single-family homes in the Boise City metro area through the second quarter of 2021, the highest among the 100 largest U.S. metros, versus 17.4% nationally. While those population and price measures use different geographies and do not measure condo values, they describe the broader setting in which this segment has evolved.
Condominiums accounted for 1.57% to 2.33% of annual closings across four housing categories in the supplied data. Their share was 1.99% in 2015 and 1.92% in 2025. Condo closings peaked at 284 in 2017 while the low was 149 in 2022. Despite regional growth and broader price gains, condo sales remained a small and uneven flow. Individual building deliveries show up clearly in its annual total.
How building deliveries appear in the totals
The Afton and One Nineteen illustrate an earlier wave. At One Nineteen’s 119 S 10th Street address, 11 closings appeared in 2016 and 14 in 2017. The Aftons’ first-phase address at 611 S 8th Street contributed 26 in 2017. A second Afton address at 880 W River Street had 29 in 2019, even though the countywide condo total barely changed from the prior year.
A later wave came from Harris Ranch Lofts in East Boise. Sales at its six Haystack Street addresses numbered 12 in 2022, 35 in 2023, 37 in 2024, and 29 in 2025. These are all recorded closings at the addresses; the data does not consistently identify an initial developer sale. Their concentration nevertheless shows why an annual count requires building-level context.
Price growth and a changing mix of sales
The median condo sale price rose 175% from 2015 to 2025. For single-family homes, the corresponding median rose about 144%, from $225,000 to roughly $549,700. The average tells a different comparative story: condo averages rose about 138%, while single-family averages rose about 151%. Unit size, building, condition, and the share of higher-priced sales changed over the decade.
The price distribution makes the change tangible. In 2015, 175 of 205 condo closings were below $300,000. In 2025, only 39 of 190 fell below that nominal threshold, and 97 closed between $300,000 and $499,999. Fixed dollar brackets don't account for inflation; they show how different the mix of transactions can look to a present-day buyer.
Recent marketing time
Within Boise city limits, the median condo that closed spent 22 days on market in 2024 and 24 in 2025, compared with 11 and 12 days for single-family homes. Earlier years were less consistent.
From a buyer’s side, a condo is more than a floor plan at a price. The decision can reach into the association’s finances and insurance, parking rights, rental rules, financing, and the experience of owning in that building. The closest alternative might be another unit down the hall, a nearby project with very different dues, or a single-family home in the same price range.
This is an area where building-specific research and specialized representation can matter: presenting the residence clearly, making ownership details accessible, and explaining how it compares with the choices a buyer is likely to consider. The longer median makes that work worth attention. The series gives Urban Boise a baseline to monitor as its own sales history develops.
What the long view can tell you
The decade does not yield one growth rate or one level of competition that applies to every condo. It shows a small category shaped by building releases and by changes in the varied properties that transacted in any given year. For a particular residence, its building history, association, layout, parking, condition, and competing inventory remain the best comparisons and indicators.
About the data
Source: Urban Boise analysis of Intermountain MLS Ada County closed-sale exports for calendar years 2015–2025. Closings include Sold and Unpublished Sold records and are grouped by closing date. Market share uses condo, single-family, single-family with acreage, and townhouse sales; manufactured-home and other categories are excluded. Single-family price and DOM comparisons use the Single Family type alone. Prices are nominal. Days on market and prices describe closed listings, not current inventory or repeat-home appreciation. Development-address counts include possible resales.
