Buyers: Where does a price sit?
It works out the property’s price per m² (price ÷ floor area) and ranks that against the matched resale sales in CF3 over the last 12 months, the same sales the spread chart above draws. Both size and price move the result.
Both boxes start at the market’s middle: the median sale price, and the floor area that price buys at the median £/m² here, so the default sits on the median. Type over either. It is not a valuation of any single home.

The band is the same sum at the middle 60% (p20–p80) of those sales: what the cheaper and the more expensive end of this market paid per m² for the same space.
It knows the area and the size, and nothing else about the home. Condition, floor, outlook, lease length and garden are what a valuation is for.
