Data Source

All house price information is derived using Nationwide mortgage data. This data is extracted monthly from mortgage applications at the approvals stage and after the corresponding valuation has been completed. Approvals data is used as opposed to mortgage completions since it should give an earlier indication of current trends in prices in the housing market.
