Get alerted to new house sales in your postcodes, streets or towns from HM Land Registry Price Paid Data (OGL). Reads each monthly update, alerts only new sales, adds sector comparables (price vs median) and 12-month area stats. Slack/webhook alerts, CSV. England and Wales.
Fix: sales not delivered because the run hit the max total charge or the 5,000-alert cap are no longer marked as seen, and the monthly-file ETag is not advanced, so they are alerted on the next run (previously they were lost).
Watches after the budget is used up are still checked for free work (baseline, deletions, summary); only paid sales are deferred.
OUTPUT and the final summary row now show incomplete, deferredSales and a per-watch deferred list; the status message says "N sale(s) deferred to next run (max total charge reached)". An exactly used-up budget is no longer reported as stopped.
