Has anyone found any house price growth statistics which reflect the GENUINE growth in the value of houses, not the change in type of house in an area? What I mean is, if a town has a lot of terraced houses, selling at around £50,000, and a developer builds some luxury detached houses which sell at £200,000, then the average house price might appear to be £75,000, a growth of 50%. However, the terraced houses are still selling for £50,000 so the growth is actually 0%. The genuine measure of house price growth can only be based on houses that existed at the start of the measuring period, and still exist at the end. Does anyone know any stats like that?

Hometrack and the Land Registry give info for a postcode separated into terraced, semi, detatched and flats. With Hometrack the free data is only 3 months old but you can track it long term by keeping records. Also you can get actual sale prices for individual properties back to about 2000, great fun. With the Land Registry they just give you the raw data which shows a lot of random variation quater by quarter. Remember that house prices also increase because most of us are improving our houses .. loft conversions, upstairs bathrooms, extensions, etc. Hope that helps.
