​National Survey of Mortgage Originations (NSMO) Public Use File

The National Survey of Mortgage Originations (NSMO) is a component of the National Mortgage Database (NMDB®) program.  It is a quarterly mail survey jointly funded and managed by the Federal Housing Finance Agency (FHFA) and the Consumer Financial Protection Bureau (CFPB).  NSMO provides unique and rich information for a nationally representative sample of newly originated closed-end first-lien residential mortgages in the United States, particularly about borrowers’ experiences getting a mortgage, their perceptions of the mortgage market, and their future expectations.  This voluntary survey is administered by Westat, a survey and data collection corporation, to the borrowers associated with the sample mortgages.  The respondents can either return the English questionnaire by mail or complete the survey online in English or Spanish. 

NSMO draws its sample from newly originated mortgages that are part of the NMDB, which is a 1-in-20 sample of closed-end first-lien residential mortgages newly reported to one of the three national credit bureaus.  Beginning with mortgages originated in 2013, a simple random sample of about 6,000 mortgages per quarter is drawn for NSMO from loans newly added to the NMDB.

The NSMO public use file was updated on February 20, 2020.  It is based on the first 21 quarterly waves of the survey, containing 29,962 sample mortgages originated from 2013 through 2017.  The original file was published on November 8, 2018, containing mortgages originated from 2013 through 2016.


  • The NSMO survey has been conducted quarterly since the first quarter of 2014.  The 25th wave of the survey went into the field on February 3, 2020.  The survey package sent to the respondents can be viewed here.

  • Data on loans originated in 2017 were released on February 20, 2020.  A file containing data on loans originated through 2018 should be released by the end of the calendar year.
