About this home

A Rare Sparkill Opportunity With NYC Proximity & Extraordinary Potential Tucked into the natural slope of the land, 450 Valentine Avenue is anything but an ordinary home. Set in a private, scenic setting with expansive views through oversized windows, this distinctive 4-bedroom, 3-bath residence offers approximately 2,650 square feet of flexible living space, a two-car garage, multiple levels of living, two kitchens and two laundry areas. Located just off Route 9W, the property offers the rare combination of a peaceful Hudson Valley setting and exceptional access for the New York City commuter. The home is ready for its next chapter. While the interiors are dated and await a thoughtful renovation, the opportunity here is in the bones: dramatic windows, natural elevation, flexible living spaces, garage parking, established terraced gardens and a layout that could lend itself beautifully to a modern renovation or multi-generational lifestyle. Imagine opening the windows to the views, creating a cohesive designer interior, transforming the kitchens and baths, and bringing the terraced gardens back to life. There is even a wonderful history here—the property once included chickens and bees, reflecting the unique connection between this home and its natural surroundings. For the buyer who can see beyond today's finishes, this is an opportunity to create something truly special in one of Rockland County's most desirable commuter locations. A property with character, scale, views and upside is increasingly difficult to find. 450 Valentine Avenue isn't simply a house that needs updating. It is a house waiting to be reimagined. "Offered as an exceptional renovation opportunity for buyers seeking location, views, flexible living space and significant potential."
