NY Real Estate Agents - What MLS access do I need

[Damien J Michalosky]

Fellow New York Real Estate Agents,

I have been a Real Estate Broker for about 15 years in Massachusetts. I have recently gotten my broker's license in New York. I am trying to figure out what MLS to join. I am going to be doing business in Brooklyn, Bronx, Westchester and Rockland Counties primarily. I see there is a NY State MLS which claims to cover all areas but there are also Brooklyn MLS, Hudson MLS, Long Island MLS and Staten Island MLS and maybe more. I am interested in current and historical data as well. Which MLS do I need to join?

In Massachusetts, this is something we don't need to think about, we only have 1 MLS there, MLSPIN.

Thank you in advance for any advice.
