Treasure Valley Market Update | Ada & Canyon Counties Are Telling Two Different Stories
September 7-13, 2026
We're another week into September, and this week's Treasure Valley housing numbers are a good reminder that “the market” isn't one single thing.
Ada County and Canyon County had noticeably different weeks.
Ada saw more homes come onto the market and more homes go pending, even as closings slowed. Canyon County, meanwhile, saw fewer new listings, fewer pending homes and a significant week-over-week drop in closings.
Does that mean one county is suddenly booming and the other is crashing? No.
Weekly real estate data can move quickly, especially when we're comparing relatively small seven-day windows. But these numbers can help us see where buyers are active, how much inventory is available and what trends are worth watching over the next several weeks.
Here's what happened this week.
📍 Ada County | Buyer Activity Picked Back Up
Ada County had 308 new listings this week, up 3% from the previous week.
Meanwhile, 207 homes went pending, a 13% increase.
That's probably the most interesting combination in Ada County this week.
More homes entered the market, but more homes also moved under contract.
Here's the full picture:
308 new listings ↑ 3%
182 homes sold ↓ 28%
$715,136 average listing price ↓ 10%
$702,983 average sold price ↑ 4%
$569,950 median listing price ↓ 9%
$577,500 median sold price ↑ 5%
2,224 active listings ↑ 1%
207 pending sales ↑ 13%
2.1 months of inventory ↑ 1%
Closings fell 28% this week, but that number deserves some context.
A closed sale tells us what happened weeks ago, because a home generally spends time under contract before the transaction actually closes.
Pending sales give us a more current look at homes buyers are putting under contract now.
So while fewer Ada County transactions officially closed this week, the 13% increase in pending sales suggests buyers haven't simply disappeared as we've moved into September.
Pending Vs Sold | Why You Should Care About the Difference
This is one of those real estate terms that gets thrown around constantly without much explanation.
A home that's pending has an accepted offer but hasn't completed the transaction yet.
A home that's sold has made it all the way through closing.
That means today's pending activity can eventually show up in future weeks' sold numbers.
It's also why looking at only “homes sold this week” doesn't tell us everything about what buyers are doing right now.
In Ada County this week, sold activity decreased while pending activity increased.
That's something we'll be watching.
📍 Canyon County | September Started With a Burst of Activity
Canyon County looked considerably different.
Only 111 new listings came onto the market, down 32% from the previous week.
And 65 homes closed, a 51% decrease.
The rest of the numbers:
111 new listings ↓ 32%
65 homes sold ↓ 51%
$567,182 average listing price ↑ 9%
$489,174 average sold price → unchanged
$450,000 median listing price ↓ 1%
$435,000 median sold price ↓ 3%
1,227 active listings ↓ 1%
102 pending sales ↓ 17%
2.3 months of inventory → unchanged
Unlike Ada County, Canyon County's new listings, closings and pending activity all declined this week.
But here's where we need to be careful.
Did Canyon County Home Sales Really "Crash 51%"?
Technically, 65 homes sold this week compared with 134 the week before, which produces that 51% week-over-week decline.
But that's not the same thing as saying the Canyon County housing market has fallen 51%.
Not even close.
We're comparing one seven-day period to another seven-day period.
Closing dates can bunch together. Holidays can affect transaction schedules. A handful of higher or lower-priced properties can move weekly averages. And smaller datasets naturally create larger percentage swings.
That's why these reports are most useful when we follow them week after week.
If Canyon County closings, pending sales and new listings continue declining for several consecutive weeks, then we've got a developing trend worth digging into.
For now, this is a slow week worth watching, not a reason to panic.
Ada's Median Sold Price Was Higher Than Its Median List Price | What Does That Mean?
Here's another number that caught our attention.
Ada County's median listing price this week was $569,950, while its median sold price was $577,500.
At first glance, you might assume that means the typical home sold above asking price.
It doesn't.
These aren't necessarily the same homes.
The listing-price number represents homes newly listed during this particular week, while the sold-price number represents homes that closed this week after likely being listed and going under contract earlier.
So you can't subtract one from the other to determine how much buyers are paying over or under asking.
To answer that question, we'd need to compare the original/final asking price and closing price of the same properties.
It's a small distinction, but an important one when you're trying to understand these reports instead of simply looking at arrows.
Buyers Still Have Choices
Despite the different activity happening in each county, inventory remains fairly substantial.
Ada County finished the week with 2,224 active listings and 2.1 months of inventory.
Canyon County had 1,227 active listings and 2.3 months of inventory.
“Months of inventory” estimates how long the current supply of homes would last at the current pace of sales if no additional homes were listed.
The fact that both counties remain a little above two months tells us there are homes available but it doesn't mean every buyer has endless options.
Inventory can look very different depending on city, neighborhood, property type and price range.
Someone shopping under $450,000 may experience a completely different market from someone shopping at $800,000+.
That's why county-wide numbers are a starting point, not the whole story.
So, What Does This Mean for Buyers
This week's numbers aren't telling buyers to “BUY NOW!” or “WAIT!”
Real estate doesn't work that neatly.
But they do give buyers some useful context.
Ada County has more than 2,200 active listings, while new listings increased again this week. Buyers who are financially ready may have opportunities to compare properties instead of feeling like they have to jump at the first home they see.
At the same time, 207 Ada County homes went pending this week.
Good homes are still moving.
In Canyon County, slower activity may be worth watching, particularly if you're shopping in an area or price range where properties have been sitting longer.
The important question isn't simply “Is it a buyer's market?”
It's “What's happening with homes like the one I want to buy?”
What Does It Mean for Sellers
This week's biggest lesson for sellers might be that price and location matter more than the county-wide headline.
There are thousands of active listings across Ada and Canyon counties.
That means buyers have alternatives.
Heading into fall, sellers should pay attention to the homes they're actually competing against: similar price, similar neighborhood, similar size and similar condition.
If buyers consistently choose other homes while yours sits, the market is giving you information.
And with activity beginning to look different between Ada and Canyon counties, relying on a broad “Treasure Valley market” headline becomes even less useful.
What We're Watching Next Week
Instead of making a dramatic prediction from one week's numbers, there are three things we'd watch next:
Ada County pending sales. Was this week's 13% increase the beginning of stronger September activity, or just a one-week bump?
Canyon County activity. Do new listings, pending sales and closings rebound after this quieter week?
Inventory. Ada inventory increased slightly while Canyon decreased slightly. As we move deeper into fall, we'll be watching whether the number of homes available begins to consistently decline.
Give us another few weeks of September data and we'll have a much better picture of where the fall market is heading.

The Bottom Line
If you only looked at the number of homes sold this week, you might walk away thinking the entire Treasure Valley market suddenly slowed dramatically.
Dig a little deeper and the picture is more nuanced.
Ada County saw fewer closings but more new listings and more pending sales. Canyon County saw activity pull back across several measures. Inventory in both counties remained relatively stable.
One week doesn't make a trend.
But now we know exactly what to watch next.
And that's really the purpose of these weekly updates: not predicting the market from a handful of arrows, but helping Treasure Valley buyers and sellers understand what those numbers actually mean.
