The short answer
A PropM8 Scan is a desk check of one home from public records: what the recorded sales support, what the registers show, and what to ask before you offer. It is not a survey, a RICS valuation or legal advice.
You read it before you pay a solicitor or a surveyor, while walking away still costs nothing. Your number, what the sales evidence supports, is free. Your solicitor still does the legal work.
Why this matters for your purchase
This is the kind of thing a PropM8 Scan is built to show you early, before solicitors, surveyors or lenders are involved, while walking away still costs nothing.
