Months of inventory represents how long it would take to deplete the current inventory assuming no new homes are put on the market. It's commonly used to determine the health of a particular market.

Between 0-4 months of inventory is considered a seller's market because supply is relatively low, which means that sellers have more control to set terms or raise prices. 5-7 months signals a balanced market - there is a healthy mix of buyers and sellers. 8 or more months of inventory indicates a buyer's market, which means buyers have more negotiating power.
