## Description

### Agent Description
2.52 Acre Lakefront Estate! Renovated, Expanded Ranch with waterside Cabana, 2-story detached garage/barn, plenty of parking & private Islands on a secluded cul-de-sac location! A RARE opportunity to own an extraordinary lakefront retreat offering breathtaking water views over 640 ft of lakefront, exceptional amenities, just one hour from NYC. This beautifully renovated home features an open floor plan with a spacious living room, dining area, and gourmet chef's kitchen with stone countertops and professional-grade stainless steel appliances perfect for entertaining and everyday living. Walls of windows capture spectacular lake views while the upper deck with a screened gazebo provides the perfect place to relax and enjoy the tranquil setting. The full walk-out lower level opens to a stunning slate stone patio, seamlessly blending indoor and outdoor living. Follow the scenic path to your private waterfront dock and lakeside decking, ideal for boating, swimming, and an outdoor kitchen. A charming stone lakeside cabana with a screened area offers a unique waterfront entertaining space. Car enthusiasts and hobbyists will appreciate the impressive detached barn-style garage with loft storage, ideal for additional vehicles, jet skis, or potential future uses. Adding to the magic, the property includes private islands, one with a bridge creating a truly storybook lakefront experience. A one-of-a-kind sanctuary offering privacy, luxury, and unforgettable views.
