PMMS Definition 		
		
"Each week Freddie Mac surveys lenders on the rates and points for their most popular 30-year fixed-rate, 15-year fixed-rate and 5/1 hybrid 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, lenders surveyed each week are a 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."
