Days on market and cumulative days on market can describe different listing histories. Your neighborhood page should explain which history the chart measures before drawing conclusions from it. This guide helps real estate agents brief that explanation and its data checks. It does not set a local MLS rule or predict a property's selling time. ## What does cumulative days on market mean? **It is the cumulative listing-exposure measure defined by the supplying MLS.** NorthstarMLS documents CDOM as active market time tied to the address and current owner across qualifying listings. Treat that as its definition, not a nationwide rule. [MLS CDOM documentation, checked 2026.10.22](https://resources.northstarmls.com/hc/en-us/articles/54550171374491-CDOM-Cumulative-Days-on-Market). ## How is regular days on market different? **In the cited MLS system, DOM measures exposure for the current MLS number.** CDOM can span qualifying listing numbers. Preserve the distinction when mapping the report fields. [MLS duration definitions, checked 2026.10.22](https://resources.northstarmls.com/hc/en-us/articles/54550171374491-CDOM-Cumulative-Days-on-Market). ## Is time at the latest asking price another measure? **Yes. The cited MLS identifies PDOM separately from DOM and CDOM.** It describes exposure at the most recent listing price. Do not label that field cumulative property exposure. [MLS DOM and PDOM explainer, checked 2026.10.22](https://northstarmls.com/insights/ask-david-how-is-day-on-market-dom-data-shown-in-listings/). ## Does a new listing number always erase cumulative exposure? **Do not assume it does.** NorthstarMLS says qualifying CDOM can continue across listing numbers. Confirm the supplying MLS's ownership and relisting treatment before explaining a reset on your website. [MLS relisting treatment, checked 2026.10.22](https://resources.northstarmls.com/hc/en-us/articles/54550171374491-CDOM-Cumulative-Days-on-Market). ## Does a sale affect the cumulative history? **The cited MLS states that CDOM starts over after Closed status when the property is listed again.** Other systems require their own confirmation. Keep the rule source attached to the field mapping. [MLS ownership-change treatment, checked 2026.10.22](https://resources.northstarmls.com/hc/en-us/articles/54550171374491-CDOM-Cumulative-Days-on-Market). ## Do pending periods count toward CDOM? **Not under the cited MLS's documented rule.** Its CDOM documentation excludes Pending, TNAS, and Withheld periods. Do not extend those exclusions to your report without checking its source. [MLS excluded statuses, checked 2026.10.22](https://resources.northstarmls.com/hc/en-us/articles/54550171374491-CDOM-Cumulative-Days-on-Market). ## Is time off market a universal reset rule? **No verified universal interval is established here.** The applicable interval is **UNRESOLVED** until the supplying MLS confirms it. The cited explainer and rules article use different interval wording, so this page does not reproduce a reset-day count. [MLS explainer, checked 2026.10.22](https://northstarmls.com/insights/ask-david-how-is-day-on-market-dom-data-shown-in-listings/), [MLS rules article, checked 2026.10.22](https://resources.northstarmls.com/hc/en-us/articles/54550171374491-CDOM-Cumulative-Days-on-Market). ## Do construction and land records need separate handling? **Check the MLS's property-type and construction-status exceptions.** NorthstarMLS documents exceptions for certain construction stages and land records. Request the equivalent rules for your own source before combining them in a chart. [MLS CDOM exceptions, checked 2026.10.22](https://resources.northstarmls.com/hc/en-us/articles/54550171374491-CDOM-Cumulative-Days-on-Market). ## Can the page calculate CDOM by subtracting calendar dates? **Avoid replacing the source field with a calendar difference.** Such a difference does not establish the documented active periods, ownership history, or exclusions. Use the supplied measure or a provider-approved reconstruction with recorded inputs. ## Is list-to-close duration the same as active market time? **Check the report's endpoints before equating them.** The MLS InfoSparks manual defines Market Time and Active Market Time with different endpoints: closing and accepted offer. Preserve the source's own labels. [MLS report duration definitions, checked 2026.10.22](https://support.sdmls.com/support/solutions/articles/150000214678-infosparks-manual-and-faqs). ## Which listings belong in a neighborhood duration summary? **State the selection rule independently from the duration definition.** Identify whether the summary concerns closed transactions, active inventory, or another documented cohort. Save the boundary, property filters, and reporting period with that selection. ## Should active and closed listings share a median? **Keep separate cohorts unless the published method explicitly combines them.** Explain what event selects records into each chart. A shared days label is insufficient evidence that the records answer the same question. ## Should the report show a median or a mean? **Preserve the publisher's chosen aggregation and label it.** Ask the data provider whether the exported duration statistic is a median or mean. Treat an undocumented aggregation as **UNRESOLVED** instead of choosing whichever description sounds familiar. ## Can cumulative exposure establish a seller's motivation? **Do not infer motivation from this field alone.** Invite a property-specific discussion when a reader asks about the history. Keep the market report descriptive and avoid unsupported claims about distress, willingness to negotiate, or a necessary price reduction. ## Should a low DOM beside high CDOM be described as an error? **Review the underlying history before calling it wrong.** Ask the MLS provider to confirm whether the fields reflect different listing scopes. Keep any disputed value marked for review rather than silently editing the source measure. ## What if the MLS and a portal show different durations? **Record the field, timestamp, and documented method used by each source.** The MLS explainer warns that cooperating websites can calculate or display these measures differently. Request clarification before alleging manipulation. [MLS display-method limits, checked 2026.10.22](https://northstarmls.com/insights/ask-david-how-is-day-on-market-dom-data-shown-in-listings/). ## What source evidence should the real estate agent retain? **Keep the permitted export, field definition, status mapping, and reviewed history examples.** Save the date on which the provider confirmed any disputed rule. Do not include private seller circumstances in the public methodology note. ## What happens when CDOM is unavailable? **Show the duration measure you can verify and label the missing field.** Do not relabel ordinary DOM as cumulative days. State **UNRESOLVED** in the working specification until the provider supplies the required definition or field. ## What should appear in the chart caption? **Show the duration field, aggregation, selected cohort, reporting period, and source.** Add a link to the supplying MLS explanation. Keep the cohort and unit readable when the chart appears on a phone. ## How should the report compare earlier periods? **Keep the duration field, selection filters, and aggregation method consistent.** Flag a rule change or a newly available field before presenting a continuous trend. Do not splice different duration measures under an unchanged heading. ## What publication permission should be checked? **Confirm the rights attached to your feed and report output.** A field's presence in an export does not settle publication permission. Send unresolved display or redistribution questions to the responsible data provider before release. ## Which acceptance checks belong in the website brief? **Test relisting, excluded statuses, changed ownership, unavailable fields, and chart labels against confirmed source behavior.** Include phone and keyboard review. Require a visible missing-data state instead of a fabricated duration. ## Who handles a correction after publication? **Assign an editor to compare the page with the provider's corrected record.** Update the figure and affected interpretation together. Save the reason for the change and any still-unresolved rule question. ## How should a real estate agent commission this report module? **Supply the approved duration field, local method, permitted data, and inquiry destination.** Ask for an editable explanation and repeatable acceptance checks through [the real estate website brief](/work).
