Final answer:
A person who acts as an intermediary in a real estate transaction is known as a broker, which is similar to banks that act as financial intermediaries by connecting savers and borrowers.
Step-by-step explanation:
An intermediary in business acts as a go-between for two parties involved in a transaction. For instance, in the financial sector, banks play the role of financial intermediaries, bridging savers who deposit funds and borrowers who take out loans. Here, unlike a social scenario like a blind date, the parties (savers and borrowers) do not meet directly, and their transactions are pooled together by the financial institution for lending purposes. In the case of a real estate transaction, the correct term for an intermediary who represents one of the parties is a broker.
