Treasure Valley Home Sales See a Boost in October
A number of housing market variables have aligned this fall, leading to a seasonal surprise increase in home sales for the month of October.
“With the average mortgage interest rate remaining in the lower sixes since mid-September, buyer demand and home sales have picked up,” explained Jennifer Kyser, real estate agent with The Agency Boise. “The spring and summer months are typically the busiest for real estate transactions, but today’s market is so heavily influenced by mortgage rate fluctuations that for the last two years, home sales have trended down in September (as would be expected), just to pop back up in October.” Last month, there were 1,297 total home sales in Ada and Canyon County.
Higher mortgage interest rates combined with home prices have impacted affordability for potential buyers in recent years. Today's buyers are taking advantage of the slight reprieve in mortgage interest rates, increase in available listings, and the tempered home price growth due to increases in supply. Local home values have increased a bit this year, but at a slower, more healthy pace than in the last decade.
The chart above takes a historical look at year-to-date price growth for the last four years for both Ada and Canyon County. Home price growth accelerated in 2022, then corrected downward in 2023 in response to higher mortgage interest rates. In 2024 and 2025 (so far) home prices have appreciated, but at a slower pace.
In October 2025, the median sales price for Ada County homes that closed last month was $549,900, $50 less than in October 2024. In Canyon County, the median sales price for October home sales was $425,000, a 2.4% increase year-over-year.
Another possible reason we’re seeing a rebound in sales this fall is that buyers continue to gain negotiation power. In Ada County, homes sold for an average of 96.9% or the original list price in October, meaning buyers paid about 3.1% below the original asking price. In Canyon County, buyers paid an average of 3.2% below the original list price. Many builders continue to offer interest rate incentives and/or buyer credits, adding further flexibility to the new home segment of the market.
