Start with the market evidence
Look at recent completed sales, sales volume and the spread between lower quartile, median and upper quartile prices. This gives you a more grounded view than asking prices alone.
Compare nearby districts
Compare postcode districts to understand whether a property looks cheap because it is mispriced or because the wider area carries different demand, stock or liquidity characteristics.
Check regeneration claims
Regeneration can improve confidence, but it should be checked against official timelines, delivery risk and distance from the asset.
Build a short investment note
Capture the target tenant, expected rent, comparable sold prices, running costs, local risks and your exit options before making an offer.
