Months of inventory (also called months of supply) estimates how long it would take to sell every home currently for sale if no new listings were added, given the recent pace of sales. It is one of the cleanest single measures of the balance between supply and demand.
Active listings / homes sold (or going pending) per month
A common rule of thumb: under 3 months of inventory is a seller’s market, 3 to 6 months is balanced, and above 6 months is a buyer’s market. It is a market-temperature gauge — low supply supports rising prices, high supply pressures them downward.
