House price index
From Wikipedia, the free encyclopedia
The House Price Index (HPI) is a measure of the cost of single-family houses published by the Office of Federal Housing Enterprise Oversight.
The HPI is measured monthly and tracks repeat sales of houses using a modified version of the weighted-repeat sales methodology proposed by Karl Case and Robert Shiller. This means that, to a large extent, it is able to adjust for the quality of the homes sold, unlike simple averages.
The HPI was developed in conjunction with OFHEO's responsibilities as a regulator of Fannie Mae and Freddie Mac. It is used to measure the adequacy of their capital against the value of their assets, which are primarily home mortgages.
