Are you talking about Cold Spring Harbor? Those were built in 2007.

Not much info available on Cold Spring Harbor. If these are the ones you are talking about, a public tax record search will need to be run in order to provide you with the info. You can either visit the County Tax office and search out each property, hire someone to do this for you or work with a Real Estate agent who would provide this information for you prior to either listing a property or representing you as a Buyer's Agent.

Please let me know if I can help you with any of the above.
