Under the Real Estate Settlement Procedures Act (RESPA), the builder cannot charge you more for the home if you do not use his/her affiliated lender or other affiliated companies.
RESPA is administered and enforced by the Consumer Financial Protection Bureau (CFPB).
If you are a consumer with a question or complaint related to your mortgage or mortgage servicer, please contact the CFPB’s Consumer Response team at 1-855-411-2372 (855-729-2372 TTY/TDD).
If you are a settlement service provider with questions about RESPA, please email the CFPB at CFPB_RESPAInquiries@cfpb.gov
