Donald Trump has tapped financier, Hollywood producer and hedge fund manager Steven Mnuchin as Treasury Secretary. In that role, Mnuchin would have quite a lot to say about housing, finance and policies related to mortgage lending. Mnuchin has been involved in lending before, and it didn’t go well for many homeowners.

At issue specifically is his an investment in a failing mortgage lender in 2009 called IndyMac in California. Mnuchin and other investors renamed it OneWest, and it proceeded to foreclose on tens of thousands of homes nationwide. Critics say the company could have kept some portion of those people in their homes.
