PSAR frequently receives questions about how Days on Market (DOM) is calculated and displayed in the CRMLS system. Knowing how DOM and Cumulative Days on Market (CDOM) work is important, especially because third-party real estate portals with high traffic, like Zillow, Realtor.com, and Redfin, show listing histories that many consumers view.
Here’s a quick overview of how DOM is handled in CRMLS and how we understand it works in SDMLS.
- DOM Reset: When a property is relisted, the DOM resets to zero.
- CDOM Reset: CDOM resets to zero only if the property has been off the market for 90 consecutive days or if there is a change in ownership.
- Immediate Relisting: Agents can relist a property immediately after canceling or withdrawing it.
- Display: Both DOM and CDOM are shown in CRMLS. This includes listings input through SDMLS, even though SDMLS itself does not calculate CDOM.
SDMLS (Based on SDMLS public resources)
- DOM/CDOM Reset: If a listing is canceled or withdrawn, it may not be reentered as a new listing by the same brokerage for 30 days.
- Relisting Rule: No relisting within 30 days.
- Display: Only DOM appears to be shown. There’s no evidence that SDMLS calculates or displays CDOM.
Third-Party Real Estate Portals
Zillow, Realtor.com, and other portals generally show the DOM value reported by the MLS. They do not appear to show CDOM. However, they do display a detailed listing history that shows when properties were listed, withdrawn, or canceled. This means potential buyers can still see how long a property has been on and off the market, even if the DOM resets.
Key Takeaway for REALTORS®
Be prepared to explain listing history to your clients. While DOM may reset in some systems, public-facing sites may still show previous activity. CDOM is visible to agents in CRMLS, even for SDMLS listings, which can help you give better context to your buyers and sellers.
