Read topic →Stale Property Listing Detection
Stale Property Listing Detection Core point A stale listing may remain online after sale, withdrawal or price change, so an active URL does not prove the property is still available. How to verify it Track first-seen date, last update and price history and verify availability directly before treating it as active supply.
Read topic →Rental Comparable Analysis
Scope the question Market data is useful only when its source, date, geography and method are known. Do not mix asking prices with transaction prices, means with medians, or a national index with a single-property valuation.
Read topic →Real Estate Data Provenance Guide
For “Real Estate Data Provenance Guide”, authenticity is established through the issuing authority and chain of acquisition, not by the appearance of a PDF or an institutional logo. If bank-account or payment instructions change by email or message, the change should be confirmed through an independent, previously verified channel before funds move; a genuine contract does not make later payment instructions.
Read topic →Property Data Update Frequency Guide

For “Break-Even Rent Analysis”, the land-registry record must be separated from marketing descriptions.

Names, identity or passport data and property.
