Days on Market

Days on market (DOM) is the number of days a property has been listed for sale or rent before being taken off the market - either because it sold, was let, or the listing was withdrawn. It is one of the most widely used metrics for assessing supply-demand dynamics in real estate.

A low DOM indicates a competitive market where properties sell quickly, often at or above asking price. A high DOM suggests weaker demand or that the property may be overpriced. Average DOM tracked at the neighborhood level is a reliable leading indicator of market temperature.

Property data APIs that include DOM allow developers to build market analysis tools, valuation models, and pricing intelligence features. It is also useful for deal-finding tools that flag properties that have been on the market unusually long.
