On a monthly basis, the New Housing Price Index (NHPI) fell 0.4% in October, the largest monthly decline since April 2009. However, the picture was mixed across the country, as prices were down in 9 out of 27 census metropolitan areas (CMAs) surveyed, but unchanged in 11 CMAs and up in the remaining 7.
Logical, though that’s not an observed phenomena as far as I know. So many factors could be in play here too such as the mix of types of housing and floor sizes etc. Everything from tiny studios to 5 bedroom mansions are included in here.
