The Consumer Financial Protection Bureau (CFPB) has filed a lawsuit alleging that Vanderbilt Mortgage & Finance, a unit of Warren Buffett’s Berkshire Hathaway, “ignored clear and obvious red flags” when approving mortgages for the purchase of manufactured homes from another Berkshire company,

The federal Consumer Financial Protection Bureau said in a lawsuit that a unit of Warren Buffett's Berkshire Hathaway ignored red flags that borrowers couldn't afford the mortgages they were given to buy manufactured homes from another Berkshire company.

Vanderbilt relied on unrealistic expectations of what borrowers would need financially after making their mortgage payment, according to the complaint.
