The Hometrack House Price Survey is based on a monthly survey of estate agents and surveyors across all postcode districts in England and Wales. The average price data is based on the contributor's opinion on the achievable selling price for each of four standard property types in every postcode district. Other variables measured include: local market conditions, average house prices, average time to sell, achieved price as percentage of asking price, change in property listings, change in registered applicants, viewings per sale. Information on the methodology used is also provided.
