The Treasure Valley real estate market is entering a period of slower growth and greater caution, as rising interest rates and affordability concerns are reshaping both residential and commercial transactions. After years of rapid expansion fueled by interstate migration during the pandemic, the region is now seeing longer listing times, tighter lending standards, and a shift in the types of buyers and developments driving activity.

Franco Gelsomino, a transaction coordinator at Martinez Real Estate Services who has worked in Idaho real estate since 2003, has witnessed the region’s transition firsthand. His experience spans the recent residential surge and the current recalibration across Idaho’s fastest-growing market.

Interest Rates Reduce Buyer Pool and Prolong Sales

The most significant change in the Treasure Valley market is the sharp increase in borrowing costs. “We went from mortgage rates that were in the twos and threes to mortgage rates that are in the sevens,” Gelsomino says. “That really cut out a good chunk of buyers from the market, especially first-time buyers.”

This rise in mortgage rates has directly impacted how quickly homes sell. Properties that previously sold in 30 to 35 days now spend an average of 45 to 75 days on the market, with some listings lingering for over 120 days. The more extended marketing periods reflect a gap between sellers’ expectations and buyers’ affordability.

“Sellers are still putting properties on the market, probably not really having a grip of what the reality is from the buyer’s standpoint, with the high rates,” Gelsomino notes. As a result, price reductions have become more common, with sellers adjusting their expectations after properties fail to attract offers at initial listing prices.

Investor Activity Maintains Transaction Volume

As higher rates sideline traditional homebuyers, investors have stepped in to fill much of the gap. “Investors have been really sweeping through the market, investing in everything from single-family homes to condos to townhouses,” Gelsomino observes.

This trend has helped maintain overall transaction volume even as affordability challenges push many would-be owner-occupants out of the market. Investment purchases now account for a larger share of sales, changing the market’s composition and supporting price stability in some segments.

Shift in Development Focus: Rentals Over Ownership

The influx of new residents from coastal states during the pandemic initially drove a surge in residential development. However, the focus of new construction has shifted. “Most of the land that has been developed in the last several years was developed for rental properties, condominiums, and apartments,” Gelsomino explains.

This emphasis on rental housing reflects the realities faced by buyers who cannot qualify for mortgages due to higher rates and stricter requirements. With homeownership less accessible, rental demand has increased, making multifamily development particularly attractive to investors and developers.

Geographic Expansion Moves Westward

Although the pace of new development has slowed compared to the pandemic peak, the Treasure Valley continues to grow due to limited land in established areas. “As Boise has saturated from the perspective of development in the last ten years and Meridian is in the process of almost saturating as well, the remaining land is just west of Boise and Meridian,” Gelsomino says.

This shift is steering new projects toward Canyon County, including cities like Nampa and Caldwell. “Canyon County at this point becomes the last place within the Treasure Valley to continue that kind of growth, since the two major cities have already reached the saturation point.” The geographic expansion reflects both land constraints and ongoing population growth, ensuring that development continues even as the market cools in core areas.

Commercial Market Remains Stable, With Pockets of Strength

The commercial real estate sector has shown more stability than the residential market, despite some moderation in activity. “Commercial real estate has been pretty stable, very steady so far. We haven’t seen any major changes,” Gelsomino reports.

Leasing activity remains strong, particularly among small and medium-sized businesses looking for new locations. Multifamily residential projects continue to attract investment, driven by persistent rental demand from new arrivals. Industrial development, especially warehouse construction, stands out as a growth area. “One thing that I see still going strong in the Treasure Valley to this day is the building of large warehouses. They’re coming up pretty much everywhere along Interstate 84 from downtown Boise all the way to the end of Canyon County,” Gelsomino says.

Tighter Lending Standards Add to Market Friction

Both residential and commercial lenders have tightened their credit requirements. “All the banks and credit unions are requiring a little bit better credit and better collateral to qualify,” Gelsomino explains.

These stricter standards have led to more deals falling through, as buyers struggle to meet new lending criteria. The combination of higher rates and more stringent underwriting is making it more difficult for buyers across all property types to secure financing, further slowing transaction volumes.

Market Outlook: Opportunities Amid Adjustment

Despite current headwinds, Gelsomino remains optimistic about the Treasure Valley’s long-term prospects. The region’s steady population growth and scarcity of developable land in core areas continue to support demand for new projects, especially in Canyon County.

He identifies several sectors as attractive for investment: “Warehousing is a good investment right now because the demand for warehouse space is there. Multifamily continues to be a good investment prospect because there is demand for housing from people coming into the state of Idaho.” Small commercial developments, such as strip centers and retail spaces near downtown Meridian and Boise, also present opportunities, with demand from small business owners remaining steady.

Looking Ahead: Cautious Optimism and Market Adaptation

The market is likely to remain in a period of adjustment as buyers, sellers, and investors adapt to higher interest rates and stricter lending standards. “I believe 2026 will prove to be a year where there’s going to be some reality check depending on how the situation with rates and inflation goes,” Gelsomino suggests.

Despite these adjustments, the underlying factors that made the Treasure Valley attractive during the pandemic—relative affordability, quality of life, and a business-friendly environment—remain in place. These strengths continue to draw new residents and businesses, supporting the region’s long-term growth.

The Treasure Valley’s evolution from a pandemic-driven boom market to a more measured, sustainable growth environment mirrors broader national real estate trends. However, the region’s specific advantages—limited land in core areas, strong rental demand, and robust commercial and industrial activity—position it for continued expansion as market conditions stabilize.

As interest rates and lending standards continue to influence who can buy, build, and invest, the Treasure Valley’s real estate market is adapting. While the days of rapid appreciation and quick sales are over for now, the region’s resilience and appeal suggest that, once the current adjustment period passes, it will remain a key growth market in the Mountain West.
