Owner-Occupancy Fraud and Mortgage Performance
We identify occupancy fraud — borrowers who misrepresent their occupancy status as owner-occupants rather than investors — in residential mortgage originations.

Occupancy fraud allows riskier borrowers to ...

We show that a key benefit of investor fraud was obtaining a ...
