Your loan servicer is the financial institution that collects your monthly mortgage payments and has responsibility for the management and accounting of your loan. It is possible that the owner of your mortgage also services it, however many loans are owned by groups of investors and these investors hire loan servicers to interact with homeowners on their behalf. Many lenders also have the loan servicers handle all contact with homeowners.
For example, your servicer could be “Bank A” but the investor in your loan could be Fannie Mae, Freddie Mac or a group of investors.
