The stats you are requesting are available to Realtors through the Realtors' version of MLSl.
It sounds to me like you are looking to hire a Realtor to market your home. In my opinion,, there are two kinds of agents; selling agents and marketing agents. Do you really want to hire a selling agent to market your home?
Marketing agents can be anywhere in the State and will market your property to ALL 25,050 agents on the Long Island Board of Realtors and they will ALL be encouraged to come in and sell your house.
