DOM stands for Days on Market. It is a measurement of the age of a listing. It is the total number of days the listing is on the active market before an accepted offer.
CDOM stands for Cumulative Days on Market. It is the total market time accumulated on a property address. CDOM is calculated when a property has been in the FlexMLS system and expires or withdrawn and relisted within 90 days. It adds the previous DOM with the current DOM and puts that amount in the CDOM column.
You will find the CDOM column in a variety of places on FlexMLS’s website. You will see it on the Detail\History tab, Compare tab, Price Analysis page of the CMA, and the Statistical CMA.
CDOM does not carry over for sold or pending listings.
