Boulder County townhouse, condo sales fell 18% through September

Boulder County sales of townhouses and condos fell 18% in the first nine months of 2026 compared with the same period last year, while single-family sales fell 1.6%, according to the Denver Metro Association of REALTORS’ September county market update.

In September, 59 townhouses and condos sold, down 28.9% from 83 a year earlier. Their median sale price was $495,000, down 3.9%. Single-family sales fell 12.6% to 222, while the median price rose 3.6% to $829,000.

Active listings were lower than a year earlier in both segments: 422 townhouses and condos, down 12.6%, and 896 single-family homes, down 15.1%. Properties also took longer to sell: 93 days for townhouses and condos, compared with 83 a year earlier, and 74 days for single-family homes, up from 69.

The countywide measures give buyers a mixed picture. Townhouse and condo prices were lower and selling times longer, but there were also fewer listings. Single-family prices rose even as sales declined. These figures do not show the terms of individual transactions.

Year-to-date median prices through September were $488,500 for townhouses and condos, down 2.3%, and $848,000 for single-family homes, up 1.0%. For regional context, the association’s September metro-wide affordability index was 117 for townhouses and condos and 70 for single-family homes. The index compares median household income with the income needed to qualify for a median-priced home at prevailing rates; it is not specific to Boulder County.

The association cautions that monthly activity can swing because of small sample sizes. Its sale-price measures also exclude seller concessions and down-payment assistance, so they do not reflect every term that may affect a buyer’s transaction.
