Polygon Research has implemented a rules-based QM flag for the entire HMDA-reported universe (2018–2024), utilizing only publicly available fields. Each loan is classified as QM, Non-QM, or Out of Scope (loans outside the ATR/QM framework). Here are some of the practical applications:
- Size the Non-QM markets and track market share by year, lender, channel, and geography with precision.
- Isolate Non-QM drivers - instantly see if a loan triggered Non-QM status due to pricing (APOR spread), product features (IO/Balloon), or points and fees.
- Map opportunity & risk - Overlay Non-QM lending patterns on census tracts, income categories, and demographic data to identify underserved markets.
