High Mortgage Rates Are Keeping Buyers on the Sidelines — What It Means for Boise Real Estate

The housing market has a math problem.

Home prices remain high. Mortgage rates remain elevated. Put those two together, and the monthly payment required to buy a home is keeping many would-be buyers from making a move.

That isn’t just a residential real estate story. It can influence apartment demand, retail spending, workforce mobility, development decisions, and ultimately Boise commercial real estate.

According to reporting by IBR Staff in the Idaho Business Review, national existing-home sales declined nearly 2% in July while the median home price climbed above $434,000. Mortgage rates also moved higher in early August, adding another affordability challenge for buyers.

The original Idaho Business Review article, “National home sales decline amid rising prices and interest rates,” was published August 14, 2026.

For Boise, the important question is what happens if this higher-cost housing environment lasts longer than buyers, sellers, and developers originally expected.

The Housing Market Is Stuck Between High Prices and High Rates

The national housing market isn’t collapsing.

But it isn’t moving normally either.

Existing-home sales have been running at roughly 4 million transactions annually for about three years, according to data cited by the Idaho Business Review from the National Association of Realtors.

That’s well below the historical pace of approximately 5.2 million annual sales.

July provided another example.

Existing-home transactions declined almost 2% from June. Compared with July 2025, sales were roughly flat.

At the same time, the national median home price moved above $434,000, approximately 2% higher than a year earlier.

Then there’s the financing side.

The average 30-year fixed mortgage rate reached 6.69% during the first week of August after increasing for five consecutive weeks.

Each of these conditions would create some resistance by itself.

Together, they create a much bigger affordability problem.

Higher home prices require larger down payments.

Higher mortgage rates increase monthly payments.

Insurance and property taxes add additional costs.

The result is that households that might have purchased homes several years ago may no longer qualify — or may simply decide the monthly payment isn’t worth it.

First-Time Buyers Are Feeling the Pressure

First-time homebuyers provide one of the clearest signs of the affordability challenge.

Historically, first-time buyers have represented roughly 40% of existing-home transactions, according to the figures cited by the Idaho Business Review.

In July, their share was only 29%.

That matters beyond the entry-level housing market.

Real estate depends on movement.

A first-time buyer purchases an entry-level home.

That seller moves into a larger property.

The next seller may move into another home.

One transaction can help trigger several others.

When the first rung of the ladder becomes difficult to reach, activity farther up the market can slow as well.

Inventory is another complication.

Approximately 1.54 million existing homes remained available nationally at the end of July. That represented a little more than four months of supply.

A market with roughly five to six months of inventory is generally considered more balanced.

So buyers face an unusual combination.

Affordability is difficult, but housing supply still isn’t plentiful enough to create strong downward pressure on prices.

That helps explain why transaction volume can remain weak while prices remain relatively firm.

Why This Matters for Boise Multifamily

This is where the residential housing market begins connecting directly with Boise commercial real estate.

When renters can’t afford to become homeowners, many remain renters longer.

That can support apartment demand.

We recently discussed improving Boise multifamily fundamentals, including stronger apartment absorption, declining vacancy, and renewed rent growth.

The mortgage market could reinforce that trend.

Consider a renter who planned to purchase a house.

If mortgage rates were significantly lower, buying might make sense.

At today’s rates and prices, the required monthly payment could be dramatically higher.

That household may decide to renew its apartment lease for another year.

Multiply that decision across thousands of households and it begins affecting Boise apartment vacancy.

This creates an interesting dynamic.

High interest rates make multifamily development more difficult because construction financing becomes expensive.

At the same time, those same high rates can make homeownership less affordable, keeping more households in rental housing.

In other words:

High rates can restrict new apartment supply while simultaneously supporting apartment demand.

For Boise multifamily investors, that’s an important relationship to watch.

Housing Affordability Can Affect Boise Retail and Employers Too

Housing costs also influence how consumers spend money.

A household paying more for rent or a mortgage has less discretionary income available for restaurants, entertainment, fitness, shopping, personal services, and other purchases.

That matters for retail leasing Boise businesses.

Retailers don’t operate in isolation from housing.

When evaluating a new location, businesses look at household income and population growth.

But those numbers don’t tell the whole story.

What matters is how much income households have left after paying major expenses.

Housing is usually the biggest one.

A market can have strong household incomes but still experience pressure on discretionary spending if housing costs absorb a growing percentage of those incomes.

Employers face a similar issue.

Companies considering Boise locations need workers.

Workers need housing they can afford.

If employees have difficulty purchasing or renting within a reasonable distance of their jobs, businesses may eventually face recruitment and retention challenges.

That makes housing affordability an economic-development issue as much as a residential real estate issue.

Boise Development Faces the Same Interest-Rate Problem

Developers are also dealing with higher borrowing costs.

The interest rate affecting a homebuyer isn’t identical to the financing used for an apartment building, retail center, industrial project, or office development.

But the underlying capital environment affects nearly every type of real estate.

Higher borrowing costs reduce how much developers can afford to pay for land.

They increase construction carrying costs.

They can reduce investment returns.

They can make refinancing more difficult.

And they raise the income a new development needs to generate before the project becomes financially feasible.

That creates another potential supply constraint.

Some Boise development projects that made sense under lower-cost financing simply don’t pencil under today’s assumptions.

Projects get delayed.

Land sits longer.

Developers wait for better financing conditions, lower construction costs, stronger rents, or some combination of the three.

That can eventually reduce future supply.

Local Insight: Don’t Wait Only for Mortgage Rates to Fall

There is a tendency in real estate to focus on one number:

Interest rates.

When will rates fall?

How far will they fall?

What happens when mortgage rates get back near 6%?

Those are reasonable questions.

But from a Boise commercial real estate perspective, I would watch the entire equation.

Interest rates are only one part.

Home prices matter.

Housing inventory matters.

Apartment rents matter.

Population growth matters.

Employment matters.

Wages matter.

New construction matters.

Consumer confidence matters.

A decline in mortgage rates would certainly improve purchasing power.

But lower rates could also bring more buyers back into the market at the same time, potentially supporting home prices.

That’s why affordability doesn’t automatically return simply because mortgage rates decline.

For Boise multifamily investors, prolonged barriers to homeownership could continue supporting renter demand.

For residential developers, lower rates could eventually unlock additional buyers and improve absorption of new communities.

For commercial developers, easing capital costs could make more projects financially viable.

For retailers and other Boise tenants, improved housing affordability could eventually free more household income for discretionary spending.

And for employers, a healthier housing market could make recruiting workers into the Treasure Valley easier.

The national housing slowdown therefore matters well beyond residential brokerage.

Housing sits underneath much of the local economy.

People decide where to work partly based on where they can afford to live. Businesses decide where to open based partly on where those people live and how much they spend. Developers decide what to build based on that demand.

That’s why Boise commercial real estate investors should continue watching mortgage rates and home sales even if they never plan to buy or sell a single-family house.

Housing isn’t separate from commercial real estate.

It’s part of the foundation supporting it.
