YieldRadar maps gross rental yield across every UK postcode district, recalculated monthly from live asking prices and rents. Compare any two areas side by side, filter by property type and bedroom count, and run stamp duty, yield, and cashflow numbers on a specific deal. The map, area comparison, budget search, and all three calculators are free. A small paid tier unlocks property-type/bedroom filtering on area pages and a couple of CSV exports.
