What the numbers mean
The median price tells you the midpoint of the homes that actually sold, not what any specific home is worth. Days on market is how long the typical home took to go under contract. Inventory shows how many homes buyers had to choose from, and months of supply estimates how long that stock would take to sell at the recent pace. For what your house would sell for, a comparative market analysis beats any regional number.
Where the figures come from
All figures on this page come from the Boise Regional REALTORS September 2026 Ada County Market Report , with data as of October 8, 2026. This page is updated monthly with sourced figures, and it does not attempt to predict where prices are going: the honest answer is that no one can forecast that with accuracy, and any agent who promises otherwise is guessing.
Sylvia's Advice
Here is what these numbers mean in practice. The median tells you where most of the market is transacting, and days on market tells you how long the typical seller waits for an accepted offer; both are context, not a verdict on any single home. Inventory and months of supply show the balance between buyers and sellers. For buyers, touring seriously and being ready to act when the right home appears still matters. For sellers, the price position and preparation do the heavy lifting, whatever the month's averages say.
