About Mortgage Rates Survey
The Freddie Mac Primary Mortgage Market Survey® (PMMS®) has evolved since its inception in April 1971 into the foremost reliable, representative source of regional and national mortgage rate trends and is relied upon by the mortgage industry and the public in gauging market conditions and evaluating mortgage loan options.
Each week Freddie Mac surveys lenders on the rates and points for their most popular 30-year fixed-rate, 15-year fixed-rate, 5/1 hybrid amortizing adjustable-rate, and 1-year amortizing adjustable-rate mortgage products. The survey is based on first-lien prime conventional conforming home purchase mortgages with a loan-to-value of 80 percent. In addition, the adjustable-rate mortgage (ARM) products are indexed to U.S. Treasury yields and lenders are asked for both the initial coupon rate and points as well as the margin on the ARM products.
Currently, about 125 lenders are surveyed each week and the mix of lender types – thrifts, credit unions, commercial banks and mortgage lending companies – is roughly proportional to the level of mortgage business that each type commands nationwide.
The survey is collected from Monday through Wednesday and the results are released on Thursdays at 10 a.m. ET. Average rates and points (and margin for ARMs) for each product are reported for the nation and the five Freddie Mac regions. The PMMS results are published extensively in the media, used in several government agency reports, and many other industry-related publications. For example, the Federal Reserve Board includes the average 30-year rate on its list of Selected Interest Rates (Statistical Release H.15) as the measure of conventional mortgage rates.
