Description
Welcome to this rare legal side-by-side duplex on a quiet, tree-lined street in the heart of Kings Park — an incredible opportunity for investors or an owner looking to live-and-rent.
Each identical unit offers an expensive living area, updated kitchen, 2 bedrooms upstairs, full bathroom, a basement, and its own private backyard — ideal for tenants or an owner-occupant who wants space and privacy. The property has been thoughtfully updated throughout, offering peace of mind and minimal near-term maintenance.
One unit is currently occupied with a paying tenant, and the other is vacant and move-in ready — giving buyers true flexibility: live in one side and rent the other to offset your mortgage, or rent both units for maximum cash flow from day one.
Enjoy low property taxes and an unbeatable location just a short walk to Main Street shops and restaurants and the LIRR Kings Park train station — a commuter's dream with easy access into the city.
Whether you're an investor seeking strong rental income or a buyer looking to house-hack your way into homeownership, this duplex checks every box.
