House price indices are costly to maintain, warranted by the column inches of coverage these provide. In 1998, the Halifax and Nationwide HPIs received virtually all the attention but sometimes provided such conflicting results that Mervyn King called for the development of new indices.
Ultimately, this led to the ONS HPI. It also led to our LSL Acadata HPIs. But indices based on offer-prices from estate agents or on price estimates obtained by survey, as well as from other interesting but non-definitive measures, now receive wide coverage. So important are house prices, and so large is the housing market, that we welcome other indices.
We publish their results for comparison with our own, and suggest that every index is valuable, provided that the data employed- and what the index reports- is understood. Acadata prepares:
- LSL Property Services/Acadata House Price Indices
LSL Acadata E&W HPI and Your Move Acadata Scotland HPI using every transaction reported to the Land Registry (LR) or to Registers of Scotland (RoS) and providing average prices at national, region and Local Government Area levels. LSL Acadata HPI results were used with those of the lenders in the FSA Mortgage Market Review Data Pack Supplement to PS12/16 dated October 2012 (see Reference), demonstrating how some analyses can best employ alternative house price data
- Illustrative House Price Calculator
Providing illustrative current values for properties for which an earlier price at a prior date are known
- Acadata Data Library
- Index Development
