Why is housing inventory growth slowing down in 2026?

After the release of the March existing home sales report, which missed estimates, the fact that housing inventory growth is slowing down has caught some people off guard. States like Florida, which some people said would see worse-than-2008 housing inventory increases in 2026, are already negative year over year.

Even the Dallas-Fort Worth-Arlington metro has negative year-over-year inventory.

Why is this happening? Slowing inventory growth is more rooted in how housing economics works, which, if properly told, isn’t always an exciting story, just a truthful one. I discussed this topic in today’s episode of the HousingWire Daily podcast and I want to go through the basics here.

Housing inventory is getting back to normal

I wasn’t a fan of the housing market from 2020 to early 2022 because housing inventory reached levels I deemed savagely unhealthy. Record-low levels of listings created massive price inflation that we are still dealing with today. Think about it: We had 3.25%-5% mortgage rates in the decade before COVID, but we never had home-price growth run rampant because inventory was higher then.

Normal inventory, according to the National Association of Realtors, is between 2 and 2.5 million. I think the housing market is perfectly fine as long as we have 1.52-1.93 million total active listings and 4 months plus of supply. This is what we had last year during the peak seasonal inventory period and what we should have this year, just breaking over 1.52 million. Currently, we are at 1.36 million so we should still get above 1.52 million at some point this year. 

Now, because inventory is getting back to normal, it’s going to take a lot more demand weakness or new listings growth to get inventory growth to really pick up from here. The peak 33% inventory growth rate we had last year was good, but it was working from a lower bar. Also, mortgage rates have been above 6.50% for most of the year.  For all the drama we have had with events in 2026, it’s still the lowest mortgage rate curve for spring in many years. We can all thank a mortgage spread for that!

As you can see in the chart below, existing home sales have gone nowhere for years, but inventory has grown from record-depressed levels to almost normal again. At this point, we need to see more demand weakness, meaning homes take longer to sell, to have a similar type of growth to what we had in 2025.

Now imagine if mortgage rates were under 5.75%… It would be even harder to get more inventory growth. Even if total inventory is negative this year, we are working from a higher level, keeping prices in check and having wages outgrow home prices again in 2026.

Harder year-over-year comps

A big theme of my work since mid-June of 2025 has been that the housing market has shifted, and it did so after a year of really good inventory growth. The shift is that when rates go lower, it’s harder for inventory to grow, especially in this market when rates drop below 6.64% and head down toward 6%. The comps for 2026 will be very difficult to show much growth until we get toward mid-June.

New listings data isn’t taking off

New listings data is key to understanding how many people are listing their homes for sale — most of whom go on to buy another home. Since 2020, we haven’t had a normal year of new listings data. It didn’t matter when rates were at 3% or 8%; we never really had a year where the seasonal high period had many weeks where new listings data was running between 80,000 and 100,000.

So far this year, nothing big is happening again. We should get toward 80,000 new listings per week like we did last year, but it’s not going to be a normal year again in 2026.  For some context here, during the housing bubble crash period, new listings data was running between 250,000 -400,000 per week for years.

Conclusion

When trying to understand inventory, don’t make it complicated. Inventory is up from record-low levels, mortgage rates are lower this year than in previous years, purchase application data is at multi-year highs, new listings data isn’t back to normal yet and we are working from extreme hard comps until mid-June. That’s it. It’s not a sensationalist story, just based on solid data.
