The Mouseprice.com Street Rankings 2007 are calculated utilising the latest in automated valuation model (AVM) technology from Calnea Analytics. Each street in England & Wales was given a value representing the arithmetic mean of the current value of properties in each street. The street rankings utilise a data set of approximately 10 million properties. Various data sources are employed, however, HM Land Registry data represents the largest single dataset. Details of all property transactions that have been recorded by Land Registry since April 2000 are included within the calculation of the rankings.

The rankings aim to show the average cost of residential property ownership on a given street. As such, streets which predominantly consist of detached properties will tend to rank more highly than streets which predominantly consist of flats.

Streets with very few residential properties and streets which have not had enough property transactions in the last seven years are excluded from the rankings.
