The term primary servicer refers to companies that monitor and manage loans.
The primary servicer of a loan can be the loan originator, the mortgage banker or a third party and maintains direct contact with the borrower.
If the loan falls into default or needs special attention, a special servicer would undertake this role.
The latest Mortgage Bankers Association end of year survey shows the top CMBS servicers and servicing volumes within the industry.
