Transferring a mortgage from a borrower can only be done by paying off the existing mortgage through refinancing with a different lender. The lender is the one who can transfer the loan on their side. I’d be happy to look at your situation in more detail if you’d like. Feel free to contact me through this site. I am also on Lender411’s website too and Ranked # 1 throughout the United States. Good Luck.
What is the reason for transfer? If its to get a new rate you can usually refinance with the existing lender at a lower cost than refinancing all together with a new bank.
