Hello everyone! These past few months I've been idly shaping a short story in my mind, but due to lack of knowledge I can't give it a definite form. In this story of mine a party of real estate investors approach a mythological place (thus non-existent) throughout a broker, who informs the individuals who live there that his clients are interested in buying the place and turning it into a lavish residential area. This sets the story into motion, causing said individuals to discuss the why's and wherefore's. And this is where I'm stuck. How do this kind of transaction works? What exactly does the broker do, and what type of interactions can be found between buyers and sellers? Anything to fill me in would be very kind, thank you!
