If you get a buyers agent than you will be required to sign a listing agreement in order for them to properly represent you as so. In NYC a buyers agent isnt so popular as is with the rest of the country. And if you are looking at new condo development there is someone in my office who specializes in Astoria, LIC, Willamsburg, Greenpoint. All have great properies popping up. Keep in mind these new buildings are not so flexible on price..
