The Federal Housing Finance Agency should refrain from implementing a proposal that would overhaul the mortgage servicing compensation system as it has failed to make a “compelling case” as to why it is necessary to change a system that has “worked well for decades,” according to the Mortgage Bankers Association.In a comment letter sent to the Finance Agency earlier this month, MBA President and CEO David Stevens said the FHFA’s proposed changes would dramatically alter residential servicing, origination and secondary market operations, not necessarily for the better.“The current servicer compensation model is still the best approach and making radical changes, like the proposed ‘fee-for-service,’ will have dramatic impacts not just on originators, servicers and investors but also on borrowers in both the costs they pay to get a mortgage and the support they receive from their servicers,” said Stevens.
