Why 1 in 5 Homes Went to Investors Last Month

One in five homes sold in September was bought by an investor or someone buying a second home. That 20% share is the highest in a little over a year, according to MarketWatch.

Sales of existing homes, meaning homes that were owned before rather than newly built, still rose 1.5% from August to September 2026, according to NAR. The investor and second-home share was 15% in August 2026 and 15% in September 2025, so September was five percentage points higher than both.

The middle sale price rose 1.3% to $417,500 in September 2026, according to Reuters. The average mortgage rate, the interest charged on a home loan, was 7.03% in September 2026, the highest since January 2025. And 20.8% of homes listed for sale had a price cut in September 2026, a four-year high, according to Realtor.com.

The broader context here is simple. A 7% rate hits a family borrowing to live in the house hard, because the monthly payment jumps. An investor renting the place out, or a second-home buyer using more cash, does the math differently.

In my view, think of two piles of homes — the ones that sold, and the ones still sitting. The $417,500 number only covers the sold pile. The 20.8% with price cuts covers the sitting pile. If investors bought cheaper homes or bought from sellers ready to deal, the sold pile can stay high while more sellers cut prices.

Looking at what this means going forward, investors can keep sales moving when regular buyers freeze. That helps sales numbers but leaves more risk tied to rents and empty homes. For banks and builders, September says demand exists at 7%, but it is narrower and less about people buying a main home.
