The student- company is getting squeezed ...June 2 (Bloomberg) -- Brazos Group Inc., the largest municipal borrower in the $330 billion auction-rate securities market, is stuck with $7 billion of debt it can't refinance, restructure or buy back. The mortgage loan itself is made by a bank, a savings and loan association, a mortgage company, a credit union, or any other lender. For it to become an FHA mortgage loan, the lender would have to be approved by the Federal Housing Administration.
