Boise, Treasure Valley home sales are ‘heating up’ heading into summer

Home sales in the Boise area continued their breakneck pace into the summer, with Ada and Canyon counties both seeing double-digit leaps year-over-year during May.

All told 1,001 single-family homes changed hands in Ada County last month, nearly 20% more than the same period in 2025. Canyon County saw a 12.3% jump over 2025, totalling 521 closed sales, according to data from the Intermountain Multiple Listing Service, a real estate clearinghouse.

May’s numbers maintained a strong trend in 2026. In April, Ada County home sales jumped almost 22%, the biggest year-over-year leap since the COVID-19-crazed market of September 2020, which saw a 27.5% increase over September 2019.

Houses are selling faster, too. The average single-family home sold in Ada County in May spent 31 days on the market. That’s 12 fewer days than in April, and a 9% drop year over year, according to The Agency Boise, a real estate firm. If you cut new construction out, things are happening even faster: Existing or resale homes sold in an average of just 17 days, 10 days more quickly than the month before.

The combination — more houses selling faster — has depleted the inventory of homes for sale, The Agency found. Ada County had 1,937 houses for sale at the end of the month, according to MLS data, an 8.7% decline from a year prior. Canyon County had 1,139, a 2.9% drop.

“Real estate is hyper-local, so it’s not unusual to see multiple offers in areas with high demand and low inventory,” Julia Shoemaker, a real estate professional with The Agency Boise, said in a press release accompanying the data. “But now we’re seeing an overall increase in competition throughout the market for homes based on location, condition, and strategic pricing.”

Despite that, prices remained relatively flat year-over-year. The median sales price in Ada County was around $575,000 in May, a drop of less than one percent from 2025. Canyon County saw a 2.6% rise to $445,000.

The Agency found that 65% of homes in Ada County sold at or above their original list price, with resales commanding 99.7% of asking — the highest ratio since the firm began tracking that figure in October 2023.

“Overall, the market is heating up,” said Cassie Zimmerman of The Agency, “but the change is even more pronounced in the existing/resale segment of Ada County.”
