​In establishing benchmarks for the single-family home purchase housing goals for Fannie Mae and Freddie Mac (the Enterprises), the Federal Housing Finance Agency (FHFA) is required to measure the size of the mortgage market.  FHFA has recently revised the market forecast models to include better specifications and new macroeconomic variables that reflect factors that impact the affordable housing market.  This paper documents the statistical forecast models that the FHFA modeling team developed as part of the process for establishing the benchmark levels for the Enterprises for 2018 through 2020.
