RENTAL DATA · EARLY PREVIEW
Rental listing lifecycle
A listing period tracks one stretch of rental advertising. A brief interruption can reopen that period; a later return starts a new one.
When a listing closes
An active rental listing becomes closed when a successful detail check reports that it is no longer offered for rent. A recognized missing listing response, confirmed by a not-found listing page, also closes an existing active listing.
A timeout, blocked request, malformed response, unknown status, or missing price or address does not establish closure. Absence from a discovery scan alone does not close a listing. Older observations cannot close a listing that has newer active evidence.
Closure is recorded when observed. The platform does not wait for the reopening window to expire before marking a listing closed.
Which closure date is used
The platform keeps the first time it observed the closure. When rental history supplies a single reliable removal date, that date takes precedence for the reopening calculation.
A usable removal date must fall after the last confirmed active UTC calendar day and no later than the first closure observation. Multiple conflicting removal dates, or a same-day or later rental listing event before closure detection, make the history ambiguous. In those cases, the calculation uses the observed closure time.
Date-only evidence is compared in UTC calendar days; it does not imply a precise time of day. Observation timestamps use elapsed time. Later reliable history may fill a missing removal date without changing the first detection time.
When a listing returns
The reopening window is 10% of the saved minimum lease duration, with no maximum cap. If the duration is missing or invalid, the window is 14 days.
The calculation uses the resolved lease term saved on the closed listing. A different term in the returning offer does not change the previous period’s window. See rental source resolution for how lease facts are selected.
- At or before the window’s boundary, accepted active evidence for the same listing reopens its existing period and clears its closure dates.
- After the boundary, it creates a new period and preserves the previous closed period. An address change alone does not define a new period.
Duration comparisons use 7 days per week, 365 days per year, and 365/12 days per month. Fractional days are retained. A calendar-day difference must be no greater than the window; for example, with a 0.7-day window, a date-only closure can reopen on the same UTC date but not on the next date.
Examples
| Saved minimum lease | Reopening window |
|---|---|
| 7 days | 0.7 days (16 hours 48 minutes for timestamp evidence) |
| 30 days | 3 days |
| 6 months | 18.25 days |
| 1 year | 36.5 days |
| Unknown or invalid | 14 days |
A rental with a 7-day minimum lease that closes and returns 14 days later starts a new listing period. Its previous closure remains in the record, allowing a possible short rental turnover to remain distinct. A listing with an unknown lease returning exactly 14 days after the observed closure instead reopens its existing period.
What the status tells you
Closed does not mean confirmed rented. A listing may disappear because it was rented, withdrawn, or changed. Reopening and separate listing periods are interpretation rules, not proof of occupancy or a signed lease.
The rule operates on observed updates. It does not guarantee detection of every brief closure or reopening between checks. Closed listings remain eligible for routine refresh within their reopening window; later discovery can still identify a new active period. The window does not increase how often checks run. Existing historical periods are not automatically split or rewritten.
