An excerpt from this article in HW:

To provide relief more quickly under the settlement, Chase executives are addressing the borrower fatigue with a letter sent to borrowers notifying them that their loan was refinanced into a new mortgage with a lower interest rate. No documentation was needed. Chase owned the loan.

Borrowers receiving these letters saved an average of $300 per month on their payments, according to a statement from the bank sent to HousingWire.

Chase is sending different letters to other underwater borrowers. All that is required in order for a principal reduction on their loan is a signature sent back with the included self-addressed stamped envelope the bank provides.

Roughly half of the borrowers targeted by most major servicers for principal write-down consideration agree to the deal. But nearly all of the borrowers who received a letter from Chase, sent it back with a signature, according to the bank.

“Chase is taking a proactive approach to helping homeowners. We are automatically reducing interest rates for eligible customers who are current on their mortgage payment, saving them hundreds of dollars each month,” a Chase spokeswoman said. “For many individuals and families who are struggling with their mortgage, we are lowering their payments by sending them pre-qualified modification offers, which may include principal forgiveness.”
