U.S. Housing Inventory Gives Buyers More Options in September

Housing inventory has continued to expand across much of the U.S. this September, giving prospective buyers more choices after several years of limited supply. Recent data from Realtor.com and Redfin show that the number of homes available for sale has increased from a year ago, while buyer demand remains relatively restrained.

Realtor.com reported that national active listings were 3.6% higher year over year in August 2026. Redfin’s latest data for the four weeks ending September 13 also showed active listings up 1.5% from a year earlier, while pending home sales declined 5.4% year over year.

More Homes Are Coming Onto the Market

The increase in available homes is giving buyers more opportunities to compare properties. Redfin reported that new listings reached their highest level in more than four years in August, while the total number of homes for sale reached its highest level since 2020.

Some sellers who had previously held back may also be returning to the market as the effects of mortgage-rate lock-in gradually ease and market conditions become less competitive. At the same time, slower buyer demand means some homes are remaining available for longer periods.

Regional Conditions Still Vary

Although national inventory has increased, the trend is not consistent in every market.

Phoenix, for example, recorded a 5.2% year-over-year increase in active listings in August, exceeding the national increase. By contrast, Sacramento’s active listings declined 4.3%, while San Diego’s fell 4.9%. Miami also saw active inventory decline sharply, dropping 15% year over year.

These differences highlight why national housing statistics do not necessarily reflect conditions in an individual city or neighborhood.

What More Inventory Means for Buyers and Sellers

For buyers, increased inventory can mean more properties to compare and potentially more time to evaluate price, condition, location, and financing before making an offer. Redfin’s September data showed that pending sales were at their lowest level in nearly three years, suggesting that demand has not kept pace with available supply.

Sellers may need to pay closer attention to local competition and pricing. Redfin reported that three out of five homes sold below their original asking price in August, an indication that buyers in many markets have gained more negotiating room.

However, the experience can differ substantially by location. Markets with declining inventory may continue to experience stronger competition, while areas with growing supply may require sellers to be more flexible on pricing and terms.

Practical Takeaway

The September housing market is showing a gradual shift toward greater availability, but conditions remain highly local. Buyers may benefit from monitoring new listings, price reductions, and comparable sales in their target neighborhoods rather than relying solely on national trends.

For sellers, understanding the amount of competing inventory and how quickly similar properties are moving can help inform pricing and marketing decisions. With supply and demand moving at different speeds across the country, local market data remains an important part of making informed real estate decisions.
