Monthly Interest Rate Survey (MIRS)

The survey provides monthly information on interest rates, loan terms, and house prices by property type (all, new, previously occupied), by loan type (fixed- or adjustable-rate), and by lender type (savings associations, mortgage companies, commercial banks, and savings banks), as well as information on 15-year and 30-year fixed-rate loans.  In addition, the survey provides quarterly information on conventional loans by major metropolitan area and by FHLBank district.

To conduct this survey, the Finance Board asks a sample of mortgage lenders to report the terms and conditions on all single-family, fully amortized, purchase-money, nonfarm loans that they close during the last five business days of the month.  The survey excludes FHA-insured and VA-guaranteed loans, multifamily loans, mobile home loans, and loans created by refinancing another mortgage.

 Historical Summary Tables  Adjustable Rate Mortgage (ARM) Index
The following tables present historical summary data from the Finance Board's Monthly Survey of Rates and Terms on Conventional Single-Family Non-farm Mortgage Loans. This survey is the nation's most comprehensive source of information on conventional mortgage rates and terms.

Washington, D.C. -- Many lenders use this rate to reset the interest rate on some ARMs. This index was the only index rate that federally chartered savings and loan associations could use as an adjustable-rate mortgage index in the early 1980s. For many years, this index was made available by the former Federal Home Loan Bank Board, and later by the Office of Thrift Supervision.
