Housing Inventory Rose In September, Realtor.com Says

Home shoppers saw a broader selection of properties in September 2026, according to Realtor.com’s monthly housing trends reporting. The company said active for-sale inventory rose sharply from the year-earlier period and topped 1.16 million listings nationally.

The biggest year-over-year inventory increases highlighted in Realtor.com’s October 2 report were in Minneapolis, Seattle and Buffalo, New York. Schaumburg and the Chicago metro were not listed among the top three markets for September’s largest inventory gains, so the finding is best understood as a national housing-market update rather than a Schaumburg-specific ranking.

What Changed In September

Active listings are homes currently advertised for sale. When active inventory rises, buyers generally have more homes to compare, and sellers may face more competition than they did in tighter markets. Realtor.com framed the September data as a shift toward more buyer leverage in some parts of the country, especially where listings grew the most.

That does not mean every local market moved the same way. Housing conditions can differ by neighborhood, price range, property type and commute pattern. A national inventory increase can happen at the same time that some local segments remain competitive.

Why It Matters For Buyers And Sellers

For buyers, more listings can make the search feel less rushed and may create more room to compare homes, inspection issues, asking prices and monthly payment assumptions. For sellers, a growing supply of competing homes can make pricing, presentation and timing more important.

For Schaumburg-area readers, the practical takeaway is not that local inventory surged at the same pace as Minneapolis, Seattle or Buffalo. Rather, the national data is a reminder to look closely at current local numbers before making decisions. Useful local questions include how many comparable homes are listed, how long they have been on the market, whether price cuts are becoming more common and how recent sales compare with asking prices.

What The Evidence Shows

Realtor.com’s September 2026 data page and related housing trends coverage track metrics such as active listings, inventory changes, price reductions and market conditions. The September report identified a broad national rise in homes for sale, with more than 1.16 million active listings and especially large inventory gains in the three highlighted metros.

Realtor.com also publishes weekly housing trend updates, which can help show whether a monthly change is part of a longer pattern or a shorter seasonal move. The company’s 2026 market-timing research adds broader context on how inventory and buyer activity can shift during the year.

Limits And Uncertainties

Monthly metro rankings can change quickly. September’s top inventory-growth markets may not stay in the same order in later data releases. Realtor.com’s conclusions also reflect its own listings data and methodology; other housing data providers may measure slightly different markets, time periods or listing categories.

Readers comparing markets should avoid treating one national report as a complete picture of a specific neighborhood. Local data, recent comparable sales and current mortgage terms can all affect the real-world affordability and competitiveness of a home search.
