The Final RESPA Rule outlines new requirements for mortgage disclosures including the Good Faith Estimate (GFE) and HUD-1 Settlement Statement. Key changes include requiring lenders to disclose all origination charges together, permitting borrowers to shop for certain services, establishing tolerance limits for charges at closing, and clarifying allowed fee increases. The rule aims to help borrowers understand loan costs and shop for the best deal while preserving competition among settlement service providers.
