Why Real Estate Data Doesn't Match: Causes and How to Fix It
Quick answer: Real estate data often differs across systems because MLS, PMS, CRM, and ERP platforms use different identifiers, schemas, formats, and update rules to represent the same property. Fixing it isn’t a one-time cleanup. It requires a reconciliation capability: identify candidate matches, normalize values, validate them, enrich missing fields, consolidate confirmed duplicates, resolve source priority when systems disagree, and monitor for new inconsistencies as records change.
