So here's my broker battle story:
This June I tried to get a rental in a Brooklyn Heights co-op via a broker who's been in the neighborhood for many years. I was first to the first showing, first to express interest, and brought over a check for the application fee 20 minutes after they called to request it. While I was walking over, they called and said the application fee was being increased to an entire month's rent.
After I filled out ten pages of detailed financial information, they expected me to wait in their office indefinitely, on a workday, while they tried to reach the owner. Two hours after that, they called to say that someone had just put an application in, so I wouldn't get it. Apparently, my ten-page application labeled "Application," to their exclusive listing, wasn't an application.
