What this means
In AL5, detached homes carry the highest median at £691,000, while flat / maisonette homes have the lowest at £210,000. Each figure is the median across every recorded sale of that type in the area, so the gap reflects the local mix of housing rather than any single property.
Types with too few recorded sales to give a reliable median are left out. Nothing here is estimated or modelled.
