What do you call a person who deals real estate?

A simple answer would be to call that person 'a real estate dealer.' Some people are employed by actual business owners as sales callers who go through a list of contacts and cold call them. These days, all thanks to technology, it's being done through cold calling software. Effectively, to the point where the smart programs come with AI embedded solutions to pinpoint any lack in cold calling objections. Real estate cold callers can get cue from these programs and come up with better convincing points to win over a customer. An example of such a program would be Trellus.ai, but there are plenty of solutions out there in the market these days.
