Welcome to 138 Arthur Avenue, a rare opportunity in the heart of Thornwood offering flexibility, space, and tremendous upside potential in one of Westchester County's most desirable communities. Lovingly maintained and cared for by the same family for more than 40 years, this is the type of property that buyers wait for. While the home offers tremendous value as it stands today, it also presents an exciting opportunity for a new owner to add their own personal touches and create something truly special. One of the most unique features of the property is its versatile layout, offering two distinct living areas that create an ideal setup for multigenerational living. Whether accommodating extended family, creating private guest quarters, or simply enjoying additional flexibility, the layout provides options that are increasingly difficult to find in today's market. The home also benefits from separate central air systems serving the different living areas, providing comfort and functionality throughout. For buyers with vision, there may also be an opportunity to explore conversion to a legal multifamily property, subject to approvals and requirements through the local municipality. Buyers are encouraged to conduct their own due diligence regarding future use possibilities, but the potential exists for those willing to navigate the process. Outside, your private backyard oasis awaits. The saltwater pool creates the perfect setting for summer entertaining, family gatherings, and relaxing weekends at home. Combined with the spacious outdoor areas, this is a property designed to be enjoyed both inside and out. What makes this opportunity especially compelling is the balance between current value and future potential. The home has been exceptionally maintained, yet there remains room for cosmetic updates and personalization that could significantly enhance both enjoyment and long-term value. For the buyer who can see beyond paint colors and finishes, this property offers the chance to unlock substantial equity through thoughtful improvements while benefiting from a location that continues to see strong demand. Situated in the highly sought-after Mount Pleasant community, you'll enjoy easy access to shopping, dining, parks, recreation, major highways, Metro North transportation options, and everything that makes Westchester County one of the most desirable places to live in the region. Whether you're searching for a multigenerational living solution, a property with future income potential, or simply a well-built home with outstanding upside, 138 Arthur Avenue delivers a combination of flexibility, location, and opportunity that is rarely available. Bring your vision, make it your own, and don't miss the opportunity to secure a property with exceptional long-term potential in one of Westchester's most desirable communities.
