Inventory Levels
Calculation
Definition
The number of properties currently available for sale in a market. Measured in months of supply (total active listings ÷ average monthly sales). Low inventory (under 3 months) indicates a seller's market; high inventory (over 6 months) indicates a buyer's market.
Formula
Months of Supply = Total Active Listings ÷ Average Monthly Sales
Example
Winchester has 12 active listings and averages 15 sales per month, equaling 0.8 months of supply—indicating a tight seller's market with high competition.
