The Short Answer

Housing inventory is the number of homes currently for sale. It matters because it shapes prices, competition, and how much negotiating room buyers and sellers have.

How it is measured

Inventory can be counted as the total number of active listings, or as months of supply, which compares listings to the pace of sales. Lower months of supply generally means a tighter market.

Why inventory changes

Interest rates, seasons, construction, and homeowner decisions all affect supply. When rates rise, some homeowners may choose to stay put, which can keep fewer homes on the market.
