Can Higher Mortgage Rates Increase Housing Inventory?

When they’re usually being talked about, mortgage rates are considered an affordability challenge. But rates can also affect how many homes remain available for sale on the market. When borrowing costs rise, buyer demand may cool, homes can take longer to sell, and active inventory can grow.

The way mortgage rates and housing inventory move together sometimes feels counterintuitive, but it might mean more options for buyers waiting for the right home.

Housing Inventory Growth Has Slowed but Remains Positive

According to Realtor.com’s July 2026 report, the country had 1,126,252 active listings last month. That was a 2.1% increase from both June 2026 and July 2025. Inventory was still growing, but the annual pace had slowed sharply from 10.0% in January 2026 and 31.5% in May 2025.

The last three bars in the chart below, 2.2% in May, 1.9% in June, and 2.1% in July, show more stability than the long decline that came before them. That may indicate growth is nearing a floor, but it’s too early to call it a lasting turn.

Housing Inventory Reached Its Best July Level Since 2019

The national listing count has now increased year over year for 33 consecutive months. July 2026 also marked the highest July inventory level since 2019. Compared with the 2021 low of 546,697 active listings, the July 2026 total had more than doubled.

Even so, supply wasn’t fully back to normal. Realtor.com reported that July inventory remained 11.6% below the typical 2017–2019 level and 9.1% below July 2019. The market is still suffering a gap of about 150,000 listings compared to pre-pandemic inventory levels. But experts think that gap could close before the end of the year thanks to mortgage rates.

How Mortgage Rates and Housing Inventory Move Together

Compass Chief Economist Mike Simonsen summarizes the pattern this way:

“When rates rise, inventory rises. When rates fall, inventory falls.”

He noted that if rates stay elevated, active supply may have a chance to build during the second half of 2026.

It’s worth noting how this mechanism works. Higher rates don’t necessarily persuade more homeowners to list. Instead, they can reduce buyer activity, so available homes take longer to move into pending or closed status. Those listings remain on the market and add to the active-inventory count.

Freddie Mac reported an average 6.65% rate for a 30-year fixed mortgage on August 20, 2026. Realtor.com’s July midyear forecast projected a 6.3% average and year-end rate and a 3.6% year-over-year increase in existing-home inventory for 2026. But remember that those are forecasts, not guarantees.

What More Homes for Sale Could Mean for You

• For buyers: More active listings may give buyers a broader selection and more time to compare properties. In some markets, buyers may also have more room to discuss price, repairs, or seller concessions.
• Affordability still matters: Higher rates still affect monthly payments and purchasing power. Buyers should compare the full cost of each loan and property with qualified mortgage and real estate professionals.
• For sellers: When supply builds, sellers may face more competition from comparable homes. Accurate pricing, property preparation, and attention to current buyer feedback can become more important.
• Local demand still matters: National inventory doesn’t determine the outcome for any one property. Demand can vary by metro area, neighborhood, price range, condition, and property type.

Use Local Housing Inventory To Guide Your Next Move

National reports show the direction of the broader market. Meanwhile, local MLS data shows what buyers and sellers are actually facing. Ask a local agent to review active and new listings, pending sales, days on market, price reductions, concessions, and months of supply.

An accurate local view can help buyers decide how quickly to act and can help sellers set a realistic pricing and negotiation strategy.

Bottom Line

Higher mortgage rates remain an affordability hurdle, but they can have a secondary effect: slower buyer demand may allow active housing inventory to grow. July 2026 brought the strongest July supply since 2019, although national inventory was still below typical pre-pandemic levels.
