Reading these figures
A median describes Cold Spring Harbor, not your home, which may sit well above or below it for good reasons. The tentative roll can still change before it becomes final. This page summarizes published records and is not an appraisal; verify any figure that matters in the Nassau County Land Records Viewer, and see how these pages are built.
