📅 Cumulative Days on Market (CDOM)

Cumulative Days on Market (CDOM) tracks the total number of days a property has been listed across multiple listing periods, even if the listing is removed and later relisted.

What CDOM Measures

CDOM reflects the full exposure history of a property on the MLS. Unlike standard Days on Market (DOM), CDOM typically continues when a listing is temporarily removed or relisted, unless the property remains off market long enough for an MLS reset.

Its purpose is to prevent sellers from artificially lowering market time by relisting a property multiple times.

How Cumulative Days on Market Works

  • 📅 CDOM starts counting when a property first appears on the MLS
  • 🔁 If a listing is removed and relisted, DOM may reset, while CDOM typically continues unless the property remains off market long enough for an MLS reset
  • 📊 CDOM continues accumulating until the property sells or permanently leaves the market
  • 🏷️ The final CDOM shows total market exposure across all listing attempts

This creates transparency for buyers, agents, and appraisers reviewing a property’s history.

CDOM vs. DOM: What’s the Difference?

DOM (Days on Market) measures how long a listing has been active during a single listing period. CDOM measures the total time across all listing periods.

In short:

  • DOM can reset
  • CDOM is cumulative
  • CDOM reveals true market exposure

Why CDOM Matters to Buyers and Sellers

  • 🔍 Buyers: A high CDOM may indicate prior pricing issues or limited demand
  • 💬 Sellers: CDOM affects negotiation leverage and buyer perception
  • 📈 Agents & appraisers: CDOM helps assess true market interest

CDOM is often reviewed alongside market conditions such as buyer’s markets and seller’s markets.
