Boise Housing Market Update: October 2026
Home prices ease, new construction takes the lead, and buyers gain a little breathing room.
Fall has officially arrived in the Treasure Valley, and the housing market is settling into a more measured rhythm.
The latest numbers from Boise Regional REALTORS® show a market that's cooling from its summer pace, but still demonstrating resilience compared to last year. And perhaps the most interesting development? New construction now represents more than half of Ada County's available housing inventory.
For buyers considering a move to Boise, Meridian, Eagle, Star, or the surrounding Treasure Valley, that shift is worth understanding.
Let's take a closer look at what the September data, released in October, tells us.

1. Boise-Area Home Prices Are Easing, Not Collapsing
Ada County's median single-family home price settled at $575,000 in September, down 3.4% from August.
However, prices remain 2.9% higher than September 2025.
That's an important distinction.
A monthly price decline doesn't necessarily indicate a weakening market. Seasonal changes, the types of homes selling, and shifts in buyer activity all influence median prices.
And location continues to matter.
For example:
Boise's median sales price was approximately $535,000.
Star's median sales price reached approximately $627,500.
Across Ada County, the median resale home sold for $561,065.
New construction had a median sales price of $622,704.
These differences illustrate why looking exclusively at countywide statistics can be misleading.
My perspective: If you're buying or selling, the most useful data isn't necessarily the countywide median. It's what comparable homes are doing in your specific neighborhood, price range, and property category.
2. New Construction Now Represents More Than Half of Available Homes
This is arguably the most interesting development in the latest report.
Of the 2,006 single-family homes available in Ada County at the end of September:
1,051 were new construction.
955 were resale properties.
That means approximately 52% of available inventory consisted of newly constructed homes.
New-construction inventory increased 6.4% from August, while resale inventory declined 3.6%.
Why does this matter?
For buyers, particularly those relocating to the Treasure Valley, new construction may deserve a closer look.
Depending on the builder, community, and available inventory, buyers may encounter opportunities involving financing incentives, closing-cost assistance, or upgrades.
Those incentives aren't reflected in the median sales price, which means the advertised price doesn't always tell the entire financial story.
Of course, new construction isn't automatically the better value. Lot premiums, landscaping, window coverings, HOA costs, and construction timelines all deserve consideration.
My perspective: Compare the total cost of ownership, not just the purchase price. A well-negotiated resale property may outperform a new home financially, while a builder's incentives could make new construction surprisingly competitive.
The right choice depends on your priorities.
3. Homes Are Taking a Little Longer to Sell
The average number of days on market increased from 37 in August to 39 in September.
Breaking that down:
Resale homes: 35 days
New construction: 48 days
This suggests buyers may have slightly more time to evaluate properties before making a decision.
But here's the nuance: 39 days is still approximately five days faster than the same period last year.
And with only 2.4 months of available inventory, Ada County remains below the four-to-six-month range generally associated with a balanced housing market.
So while the pace has moderated, we're not suddenly looking at an oversupplied market.
For buyers, that may mean a little more room for due diligence and thoughtful negotiation.
For sellers, it reinforces the importance of realistic pricing, strong presentation, and a strategy tailored to current competition.
4. Sales Are Slowing Seasonally, but Outperforming Last Year
September recorded 854 closed single-family home sales, down 10.6% from August.
That might sound dramatic until you consider the bigger picture.
Sales were actually 8.5% higher than September 2025, making this the strongest September for closed sales since 2021.
The market is slowing compared with summer, but it's performing better than it did a year ago.
Pending sales also declined 10.2% from August, marking the fifth consecutive monthly decline since the spring peak.
This is consistent with a market transitioning into its typically quieter fall season.
Interestingly, new construction accounted for approximately 57% of pending sales, another indication of how significant builders have become in today's local housing landscape.
5. What This Means for Treasure Valley Buyers and Sellers
If You're Buying
The combination of seasonal price moderation, slightly longer marketing times, and substantial new-construction inventory may create opportunities worth exploring.
For relocation buyers, this is an especially useful time to compare different lifestyles and housing options across Boise, Meridian, Eagle, Star, and surrounding communities.
You may find that a resale property offers a more established setting, while a new-construction community provides modern layouts, energy-efficient features, and potential builder incentives.
Neither is universally better.
The goal is to understand the trade-offs before committing.
If You're Selling
Buyers have more options than they did during the most competitive periods of the market.
That makes pricing and presentation particularly important.
It's also worth paying attention to new construction, even if you're selling a resale home.
If a nearby builder is offering attractive financing incentives or closing-cost assistance, that may influence how buyers evaluate your property.
A successful listing strategy should account for the competition buyers are actually considering, not simply what sold six months ago.
The Bottom Line: A More Thoughtful Fall Market
The October market update reveals a Treasure Valley housing market that is moderating, not stalling.
Prices have softened from August, but remain higher than last year. Homes are spending slightly longer on the market, yet sales activity continues to outperform 2025.
Meanwhile, the growing share of new construction is changing the choices available to buyers.
For anyone planning a move, the opportunity isn't necessarily about perfectly timing the market.
It's about understanding the options, recognizing value, and making decisions that support your finances and lifestyle.
