Why does Freddie Mac also have the CMHPI classic series?
For two important reasons – First, for continuity since so many researchers and businesses use the classic CMHPI in their work and understand its properties. Second, because appraisal data is also a valid observation of market conditions. Researchers can use the two series to try to predict market turning points, or may find that one series works better for their needs. For these reasons Freddie Mac will continue to publish both series.
