We went to Tracey Real Estate a couple of years ago when we were looking for our first home. The agent, Mona, was very patient because we weren't really sure what we were looking for. She showed us a lot of homes that she thought we would like and were in our budget, and we finally found the perfect one for us.
We tried other Real Estate agencies before this one, and the agents were not very helpful and didn't want to seem bothered. The agents at Tracey really know a lot about the Brooklyn real estate market, and Staten Island as well, since they opened an office there too. I highly recommend them. They have 2 offices in Brooklyn. One is on Avenue S and one is on Gerritsen Avenue.
