I have been a little slow on updating my data using the FT house price index. This index is a lagging indicator of house prices with the data being around 3 months old.
The data is from the Land Registry and also includes every transaction including properties bought for cash. This is in contrast to the Halifax and Nationwide data which is based on valuation data and is sampled.
The FT HPI data has had a much smoother data set with out wild fluctuations in monthly data.
The latest data set is here and shows house prices continuing to fall, but with the falls starting to moderate with a 0.7% fall for May.
If I remember I will now update this every month along with the Land Registry,Halifax and Nationwide data.
I do not bother with the Rightmove index as it is not seasonally or mix adjusted and is based on asking prices at estate agents, which bears no resemblance to actual purchase prices in this market.
I also do not bother with the DCLG index as this uses the Land Registry data which I already sample.
