The HMDA team at the CFPB deserves a lot of credit for creating 6 new derived fields, in particular for providing a way to combine up to 10 fields as a time for applicant and co-applicant demographic fields. This has always been a challenge for us, so kudos to the CFPB for leading the way on this.
All 6 derived fields are now included in HMDAVision filters and charts. One of them - Conforming Loan Limit
- is only meaningful when combined with FHFA
per-county conforming loan definitions for 2018. We have ingested these into HMDAVision, so our designation of whether or not a loan was conforming is accurate based on the county in which the application was made, for all US counties.
