Final answer:
Darrel's profession is a mortgage broker, who finds and negotiates loan deals with lenders on behalf of his customers, rather than lending his own capital or managing loans after issuance.
Step-by-step explanation:
Darrel works in the mortgage lending industry and his daily activities include working with multiple lenders to find and negotiate the best deals for his customers. Based on this description, Darrel's profession is most likely that of a mortgage broker. A mortgage broker acts as an intermediary between borrowers and lenders, seeking out the most advantageous loan terms that suit the financial needs of the borrowers.
Unlike a mortgage banker, who lends their own capital to borrowers, or a mortgage servicer, who manages the borrower's loan after it has been issued, a mortgage broker does not lend money or manage loans post-issuance. Rather, brokers facilitate the transaction to help borrowers obtain financing from mortgage lenders.
