If you wanted to borrow money to purchase a home, you would go to A. A MORTGAGE BROKER.
A mortgage broker serves as an intermediary between a lending institution and an individual or company.
Lending Institutions are banks, finance companies, and loan companies. Instead of you going to the bank to ask for a loan, you would go to a mortgage broker.
It is the job of the mortgage broker to establish a deal or agreement between the two parties which will benefit both parties.
