§ 1024.12 No fee.
No fee shall be imposed or charge made upon any other person, as a part of settlement costs or otherwise, by a lender in connection with a federally related mortgage loan made by it (or a loan for the purchase of a manufactured home), or by a servicer (as that term is defined under 12 U.S.C. 2605(i)(2)) for or on account of the preparation and distribution of the HUD–1 or HUD–1A settlement statement, escrow account statements required pursuant to section 10 of RESPA (12 U.S.C. 2609), or statements required by the Truth in Lending Act (15 U.S.C. 1601 et seq. ).
