On February 23, the Fed issued a final rule under Reg Z (TILA) which, pursuant to the Dodd-Frank Act, increases the APR threshold used to determine whether a mortgage lender is required to establish an escrow account for taxes and insurance for first-lien “jumbo” mortgage loans. The Fed also proposed a rule under Reg Z (TILA) that would expand the minimum mandatory escrow period for first-lien mortgage loans from one to five years and would implement new disclosure requirements contained in the Dodd-Frank Act. Comments on the proposed rule must be submitted within 60 days after publication in the Federal Register. Fed Release. Fed Final Rule. Fed Proposed Rule.
