Treasure Valley Home Sales Are Rising Despite High Rates—What That Could Mean for Boise Commercial Real Estate
High borrowing costs were supposed to cool real estate demand.
In the Treasure Valley, the picture isn’t quite that simple.
Mortgage rates remain elevated, yet home sales in Ada and Canyon counties have recently moved higher compared with the prior year. That combination is worth watching beyond the residential market.
For Boise commercial real estate, housing activity can provide clues about population movement, consumer confidence, development patterns and where future retail and service demand could emerge.
According to reporting by IBR Staff in the Idaho Business Review, the average rate for a 30-year fixed mortgage recently reached 6.55%. Even with borrowing costs remaining challenging, May home sales increased year over year in both Ada and Canyon counties.

The interesting question for commercial real estate isn’t simply where mortgage rates go next.
It’s what happens if the Treasure Valley continues generating transaction activity even while money remains expensive.
Buyers Are Adjusting to a Higher-Cost Market
The average 30-year mortgage rate reached 6.55%, according to figures cited by the Idaho Business Review. That was up from 6.49% the previous week, although still below the 6.75% level reported during the comparable period a year earlier.
The 15-year fixed rate also increased, reaching 5.93%.
For buyers who became accustomed to extremely low mortgage rates earlier in the decade, today’s environment can feel expensive.
But markets eventually adjust.
Some buyers delay purchases. Others reduce their price range. Sellers become more strategic. Builders introduce incentives. And transactions that still make financial sense move forward.
Treasure Valley sales figures suggest that process may already be happening locally.
According to MLS information provided to the Idaho Business Review by The Agency Boise, Ada County recorded 1,001 residential closings in May, representing a 19.9% increase from May 2025.
Canyon County recorded 521 sales, up 12.3% year over year.
Those are meaningful increases considering the financing environment.
Julia Shoemaker of The Agency Boise told the publication that competition is becoming more noticeable across the market, with location, property condition and pricing playing important roles in attracting buyers.
That same principle applies remarkably well to commercial property.
When financing becomes expensive, quality and pricing matter more.
Housing Activity Can Signal Future Commercial Demand
Why should a Boise commercial real estate investor care about residential closings?
Because rooftops create customers.
Every household needs groceries, restaurants, health care, fitness, childcare, banking, automotive services and dozens of other businesses.
When residential neighborhoods continue adding households and generating transactions, commercial operators pay attention.
This is particularly important across the Boise-Meridian-Nampa-Caldwell corridor.
Population growth and housing development can eventually create opportunities for:
- Neighborhood shopping centers
- Grocery and convenience retail
- Restaurants and drive-thru concepts
- Medical and dental offices
- Daycare and education businesses
- Fitness and wellness operators
- Personal services
- Automotive businesses
For retail leasing in Boise and throughout the Treasure Valley, housing growth is one of the fundamental demand generators.
Retailers don’t simply ask how many cars pass a site.
They want to know who lives nearby, how quickly the trade area is growing, household incomes and whether enough customers exist to support another location.
That’s why residential activity should remain on the radar of commercial landlords and developers.
Higher Interest Rates Still Matter for Boise Development
Strong housing activity doesn’t mean interest rates can be ignored.
Quite the opposite.
The same financial forces affecting homeowners also affect commercial developers and investors.
Higher borrowing costs can make it harder to finance new construction. They can reduce the price an investor is willing to pay for an existing building. They can also make refinancing more difficult for owners whose loans are maturing.
For developers, the equation becomes particularly challenging.
Land may cost more than it did several years ago.
Construction costs remain significant.
Financing is expensive.
And tenants still have limits on how much rent they can afford.
That can create a strange market where demand for commercial space exists but constructing enough new space to satisfy that demand doesn’t always pencil.
For existing property owners, that can sometimes be beneficial.
If new supply becomes harder to build while the local population continues growing, well-located existing retail, industrial and medical properties may become increasingly valuable.
Not every property benefits equally, however.
Just like the residential market, commercial real estate becomes more selective when capital is expensive.
Location matters.
Condition matters.
Tenant quality matters.
And pricing matters.
The Ada-Canyon Connection Is Becoming More Important
The sales growth in both Ada and Canyon counties also reinforces something increasingly important about Treasure Valley commercial real estate.
This is not simply a Boise story anymore.
People routinely live in one community, work in another and shop somewhere in between.
A family may live in Nampa, work in Meridian and spend money throughout the metro.
That means investors and tenants evaluating expansion opportunities should increasingly think about the Treasure Valley as a connected economic region rather than a collection of isolated cities.
Canyon County is particularly important to watch.
As households search for affordability and new housing continues expanding westward, commercial services eventually need to follow.
Retail typically follows rooftops.
Medical services follow patients.
Restaurants follow spending.
Employers follow workers.
Over time, residential growth can reshape the commercial map.
Local Insight: Watch What Happens When Rates Eventually Ease
The most interesting question may not be what today’s mortgage rate does to the market.
It may be what happens when borrowing conditions eventually improve.
If Ada and Canyon counties can produce year-over-year sales growth while mortgage rates remain above 6%, there could be additional demand sitting on the sidelines from buyers who simply cannot make today’s numbers work.
A meaningful decline in borrowing costs could potentially bring some of those buyers back.
That could increase residential transactions, encourage additional development and reinforce population-driven commercial demand.
There is another side to that equation.
Lower rates could also make commercial development easier to finance, allowing projects that have been waiting on the sidelines to move forward.
For Boise landlords and investors, that means the current period is worth watching closely.
Today’s higher-rate environment can reveal which locations have genuine underlying demand and which projects depended primarily on cheap financing.
Properties that continue performing when capital is expensive may tell us something important about where the strongest opportunities will be when financing becomes easier.
For Boise commercial real estate, residential activity isn’t just background noise.
It helps show us where people are choosing to live, where consumer spending may grow and where businesses could need space next.
