US house prices fell again in September and at a quicker-than-expected rate, a survey has suggested.
Prices were down 0.8% from the previous month on a seasonally-adjusted basis, according to the Case-Shiller index of 20 major US cities.
The data - which is actually an average of house prices during July, August and September - was lower than expected.
A tax credit for homebuyers expired in April, leading to a steep drop in home sales over the summer.
That same effect now appears to be feeding into house prices, which are published with a two-month lag.
