Our statistical House Price Calculator (HPC) is a tool for professionals investigating the possible current value of an individual property within a portfolio. It combines use of our Acadametrics Prices and Transactions, providing granular data unavailable from traditional indices, with unique statistical confidence limits for the estimated results, based upon ground-breaking calibration against the factual price changes for properties sold twice or more.

HPC prices incorporate: the true Land Registry (LR) prices, after smoothing (as opposed to mortgage offer prices); monthly county/London borough (as opposed to say quarterly, regional, data) unless data volumes require estimation at e.g. regional level; every transaction in England and Wales (as opposed to a sample).

Please use a full postcode, including a central space, and enter the purchase price without a currency symbol or comma separator.

Accuracy of house price calculators is limited by the granularity level at which the values are estimated. An accurate value for an individual property requires the engagement of a professional surveyor. An HPC estimated value assumes that house prices for the type and postcode shown have changed at the same rate as have the equivalent prices for the county/London borough within which the postcode lies. HPC deviations shows the range of prices, which our calibration finds for the particular property type, within the applicable county/London borough. A property in a fashionable locality, within the catchment area for a good school, might be worth as much as the “estimated value plus 2 standard deviations”, rather than the “current estimated value”, both of which we show. Our methodology is described here. Given sample data from a whole portfolio, we offer free sample revaluations with confidence limits. Please use the link on the left for details.

I understand that Acadametrics does not guarantee any accuracy and shall not be liable for any loss or damage, whatsoever, consequential upon any error, mis-description or other inadequacy in HPC and that persons using HPC do so entirely at their own risk.
