Additional Datasets

We conduct a variety of additional research and analysis that we make available to the public. This information provides ongoing insight into activities and trends in the housing market and the broader economy.

Single-Family Loan-Level Dataset

Freddie Mac makes available loan-level credit performance data on a portion of fully amortizing fixed-rate mortgages that the company purchased or guaranteed from 1999 to 2015 to help investors build more accurate credit performance models in support of ongoing risk-sharing initiatives.

Quarterly Refinance Statistics

Our quarterly analysis shows the refinancing trends of borrowers who recently refinanced their home loans.

The Federal Cost of Funds Index (COFI)

COFI is used as a benchmark for some types of mortgage loans and securities. It is calculated as the sum of the monthly average interest rates for marketable Treasury bills and for marketable Treasury notes, divided by two, and rounded to three decimal places.
