I mutual CoreLogic’s longitudinal lot-top investigation which have in public areas offered HMDA analysis while the former investigation resource does not include information regarding borrowers’ qualities, such as for instance competition and you can income. We coordinated parcel research regarding CoreLogic into the mortgage loans effective between 2007 and you can 2021 to annual HMDA inside the each of people many years.

We parsed new HMDA study to provide purchase and you may re-finance mortgage loans, once the designated by the financing step types of profession.

Almost every other records were fell. The last attempt included 37.5 million details with the common 33 percent novel suits rates around the all age.

I used several validation tests to confirm the accuracy of your test matches. I randomly picked samples and manually affirmed the newest match performance. We together with did get across-inspections towards lender and MSA distributions anywhere between all of our attempt and also the full HMDA dataset, and this displayed highest communication between them. At the same time, we utilized a stopping way to gauge the awareness your leads to all of our taste toward high Levenshtein get from the at random replacing selected matches that have alternative suits whenever multiple choices was available. In the end, we carried out further awareness studies done by varying loan amount change and you will Levenshtein proportion thresholds, and that affirmed new texture and you can robustness of our own show.
