Ada County Real Estate Market Report – May 2026
- Jun 24
- 3 min read
The Ada County housing market delivered its strongest performance of 2026 so far.
Sales activity accelerated, prices posted a significant monthly increase, homes sold faster, and inventory remained well below balanced-market levels. While some headlines may focus on the slight year-over-year decline in median price, the broader story is one of sustained demand competing for limited supply.
Market Overview
The median sales price for Ada County single-family homes reached $575,900 in May.
While that represents a modest 0.7% decrease compared to May 2025, it marks a significant 5.7% increase from April. The market has now climbed within approximately $26,000 of the all-time peak reached in 2022.
This price movement reflects seasonal demand returning to the market while inventory remains constrained.
Pricing Analysis
One of the more notable developments this month is the convergence between resale and new construction pricing.
Resale Median Price: $575,000 (-1.7% YOY)
New Construction Median Price: $575,995 (+0.2% YOY)
Historically, new construction has commanded a substantial premium. That gap has essentially disappeared.
For buyers, this creates opportunities to compare resale and new construction options on a more level playing field.
For sellers, pricing strategy remains critical. Buyers continue to have choices, and accurate positioning matters more than ever.
Sales Activity Continues to Strengthen
Ada County recorded 1,001 closed sales in May.
This represents:
+18.5% year-over-year
+10.2% month-over-month
Crossing the 1,000-sale threshold for the first time this year signals strong consumer confidence and healthy market demand.
Year-to-date closings are running nearly 16% ahead of 2025, suggesting buyer activity remains resilient despite higher housing costs and interest rate uncertainty.
Pending Sales Signal Continued Demand
Pending sales reached 1,478 transactions.
While that was slightly lower than April (-2.2%), pending activity remains up 13.4% compared to last year.
This suggests buyer demand remains healthy heading into summer even as the pace of contract activity moderates slightly.
A notable trend continues in new construction:
New Construction Pending Sales: +16.9% YOY
Resale Pending Sales: +9.8% YOY
Builders continue capturing significant buyer interest through incentives, rate buydowns, and expanded inventory options.
Inventory Remains the Key Story
Inventory increased modestly from April but remains significantly lower than last year.
Current inventory:
1,833 homes available
+5.6% MOM
-13.6% YOY
Resale inventory remains particularly tight, declining 19.1% from last year.
Limited inventory continues to place upward pressure on prices and creates competition for desirable homes.
Homes Are Selling Faster
Days on Market dropped substantially.
Current Average:
33 Days
-23.3% MOM
-2.9% YOY
The resale market is moving especially quickly:
Resale DOM: 19 Days
New Construction DOM: 64 Days
This gap demonstrates two very different market environments.
Resale inventory remains scarce and moves quickly when priced correctly. New construction inventory offers buyers additional options and often more negotiating leverage.
Months Supply Analysis
Months Supply of Inventory (MSI) currently sits at 2.3 months.
A balanced market generally requires 4–6 months of inventory.
Current Conditions:
Overall MSI: 2.3
Resale MSI: 1.9
New Construction MSI: 3.1
The market remains firmly seller-favored from a supply perspective.
While conditions are not as extreme as during the pandemic housing boom, supply remains well below equilibrium.
What This Means for Buyers
Buyers should recognize that market conditions continue to favor well-prepared purchasers.
Key considerations:
Competition remains strongest in the resale market.
New construction may offer additional leverage.
Waiting for significantly lower prices has not been rewarded thus far.
Inventory remains historically constrained.
The most successful buyers are focusing on affordability, financing strategy, and identifying opportunities before peak summer competition intensifies.
What This Means for Sellers
Sellers continue to benefit from favorable supply-demand dynamics. However, success is increasingly dependent on execution.
Today’s market rewards:
Strategic pricing
Professional marketing
High-quality photography
Strong negotiation
Homes that enter the market correctly positioned continue to move quickly and attract meaningful buyer interest.
Final Takeaway
May confirms that Ada County remains one of the strongest housing markets in Idaho.
Demand is growing, inventory remains limited, homes are selling faster, and prices continue moving upward seasonally.
For buyers and sellers alike, the market remains highly strategic rather than highly speculative. The right plan matters more than timing headlines.
