Idaho’s population growth has increased housing demand across the state, and that has put upward pressure on home prices, rents, and overall affordability. In practical terms, more people moving into Idaho means more households competing for a housing supply that does not always expand at the same pace.
That effect has not been uniform in every market. Higher-growth areas such as Boise, Meridian, and Nampa have generally felt more pressure, while conditions in other parts of the state can be less intense. Statewide, though, population growth remains one of the main reasons Idaho housing became more expensive and more competitive than it was before the pandemic.
This report provides a retrospective summary of population growth in Idaho, going back to before the pandemic. It also shows the population growth effect on the Idaho housing market looking forward into 2026.
Historically speaking, Idaho was one of the least populated U.S. states. But that has changed in more recent years, as the state steadily climbs up through the ranks.
According to a Seattle Times report published earlier this year, Idaho’s population is closing in on the 2 million resident milestone. This steady growth has been partly fueled by new arrivals from West Coast states including Washington, Oregon, and California.
Idaho’s population growth has been reinforced by an uptick in international immigration, which began with the easing of pandemic restrictions in 2022.
According to the Idaho Department of Labor, the state gained nearly 26,000 residents between July 2022 and July 2023 alone. This solidifies its position as one of the fastest-growing states in the nation.
Population growth has affected the Idaho real estate market in several ways, mainly by increasing home prices across the board. More on that in a moment.
So what’s behind Idaho’s steady population growth in recent years? As usual, it’s a combination of overlapping factors, rather than just one thing.
The influx of new residents has had a profound impact on Idaho’s real estate market and broader economy. Increased housing demand in Idaho, as well as rising demand for jobs and infrastructure, drives economic growth and development.
But rapid population growth can also present challenges, such as the potential for rising housing costs. So let’s talk about that next.
Population growth affects home prices by adding demand faster than many local markets can add available homes. As more households move into Idaho, more buyers compete for existing listings. That pressure was especially visible during the pandemic, when a flood of new residents poured into the Boise metro area and pushed competition to unusual levels.
The market has slowed down since the housing boom, and inventory levels have rebounded. When measured by both the “time on market” or “months of supply” metrics, the Idaho real estate market has returned to something resembling normalcy.
That normalization matters, but it does not erase the earlier run-up in values. Home prices, however, remain elevated. The average home value in Idaho was $482,199 as of June 30, 2026, according to Zillow.
The statewide median home price rose by more than $200,000 from the start of 2020 to the summer of 2022. Prior to that, the state of Idaho had never experienced such a sharp and sustained surge in home values.
So the main effect of population growth is not just that prices once jumped quickly. It is that Idaho now has a higher housing-cost baseline than it did before. Even with fewer bidding wars and a slower market pace, many buyers are still shopping in a market where the lasting effects of that demand surge continue to shape affordability.
Population growth also affects Idaho’s rental market because not every new household arrives ready or able to buy a home right away. Some new residents rent first while they learn local neighborhoods, while others remain renters because higher home prices or mortgage costs make buying less feasible.
That creates a spillover effect. When population growth lifts for-sale home prices, some would-be buyers stay in the rental market longer, which adds even more demand for apartments and single-family rentals. In faster-growing cities such as Boise, Meridian, and Nampa, that pressure can show up in the form of tighter rental availability and higher rents.
Over time, this is one of the clearest ways population growth reshapes housing conditions statewide: it does not only affect people trying to buy. It can also make renting more expensive, especially in markets where household growth outpaces the addition of new housing options.
First-time homebuyers often feel the effects of population growth more directly than repeat buyers do. They are usually entering the market without built-up equity from a previous home sale, so they are more exposed when prices rise faster than incomes or savings.
In Idaho, population growth has made that challenge harder by raising the cost of entry. As demand pushed home values higher, many first-time buyers needed larger down payments, faced higher monthly payments, or had to widen their search into more affordable outlying areas. Even though competition has eased compared to the peak of the boom, affordability remains a meaningful hurdle.
This is why population growth matters beyond simple market activity. It changes who can buy, where they can afford to buy, and how long it may take them to qualify or save enough to enter the market. For many first-time buyers, the issue is no longer just finding a home. It is finding one that still fits their budget.
What does the 2026 Idaho housing market forecast look like?
Population growth will continue to be a major factor for the Idaho real estate market in 2026. But it will likely be more muted than what occurred during the previous four years.
Home prices are expected to rise at a more modest pace, compared to the surge shown in the preceding graphic. A slow but steady rise seems to be the most likely scenario.
Competition among buyers has also eased, a trend that will continue in 2026. With a slower pace and fewer competing buyers, house hunters can take a bit more time for price research and other forms of due diligence.
The bottom line is that there is certainly a population growth effect on the Idaho housing market, making it more expensive. But aside from that, the Idaho housing market appears to be moving in a buyer-friendly direction for a change.

Idaho is nearing the 2 million resident mark after several years of strong growth. The state added nearly 26,000 residents between July 2022 and July 2023, and population growth remains an important factor shaping Idaho housing conditions in 2026.
The main drivers are domestic migration from other states, increased international immigration after pandemic restrictions eased, and natural increase when births exceed deaths. The article notes that many new residents have come from West Coast states such as Washington, Oregon, and California.
Population growth adds housing demand faster than many local markets can add supply. As more households compete for existing listings, prices rise. That pressure was especially strong during the pandemic, and it helped create a higher statewide housing-cost baseline than Idaho had before 2020.
Higher-growth areas such as Boise, Meridian, and Nampa have generally felt the most pressure. The article explains that these markets have seen stronger competition and more noticeable affordability strain than some other parts of the state.
Yes. First-time buyers are often affected more directly because they usually do not have home equity from a prior sale. As prices rose, many needed larger down payments, faced higher monthly payments, or had to expand their search into more affordable outlying areas.
Not every new household buys right away, so many new residents rent first. Higher home prices and mortgage costs can also keep would-be buyers in the rental market longer. That added demand can tighten rental availability and push rents higher, especially in faster-growing cities.
Compared to the height of the boom, the market appears more buyer-friendly in 2026. Competition has eased, inventory has rebounded, and buyers generally have more time for research and due diligence. Even so, affordability remains a challenge because prices are still elevated.
The most likely 2026 scenario is slower and steadier price growth rather than another sharp surge. Buyer competition has eased, and the market has moved closer to normal conditions when measured by time on market and months of supply.
The article says Idaho has been one of the fastest-growing states in the nation. It does not state that Idaho is the single fastest-growing state in 2026, but it makes clear that the state remains a national growth leader.
Buyers should also watch inventory levels, time on market, months of supply, mortgage costs, and local affordability. Population growth is a major influence, but those other factors help explain whether a specific Idaho market feels more competitive, more balanced, or more favorable to buyers.
