Pooling and Servicing Agreements (PSAs) are highly detailed legal documents that define all aspects of a CMBS loan, including the rights and responsibilities of the borrower, the lender, the master servicer, the special servicer, and the CMBS investors.
What is a Master Servicer?
CMBS loans are not serviced by the lender who issued the loan and are instead serviced by third-party entities referred to as master servicers. In many situations, the master servicer will assign the day-to-day servicing duties to another entity, known as a primary servicer.
What is a Special Servicer?
Special servicers handle the servicing of CMBS loans before and during loan defaults-- but they don't always have the borrower's best interests in mind. A servicer may attempt to help the borrower achieve a loan modification, or, more commonly, they may attempt to repossess the property in order to make the CMBS investors whole.
