I gathered this question from another question posted on
answers and wanted to know the reasoning why A
was the correct choice.
Mary is a real estate broker who is looking to enter into a
listing agreement to sell David's house. Why would David prefer to
enter into an Exclusive Agency agreement rather than an Exclusive
Right to Sell agreement?
A. The Exclusive Agency agreement will allow David to not pay a
commission to Mary.
B. The Exclusive Agency agreement will allow David to work with
more than one broker.
C. The Exclusive Agency agreement gives David the option to find
a buyer himself and not have to pay Mary a commission.
D. The Exclusive Agency agreement limits the amount paid in
commission to only 3% of the sales price.
Can you explain the reasoning why the
answer is A, B and C sounds correct also.
