for $1,225,000 with 4 bedrooms and 2 full baths. This 2,178 square foot home was built in 1952 on a lot size of 0.2976.
Tucked quietly along a peaceful Castro Valley street, this home is the kind of opportunity buyers are always hoping to find; a property that feels warm and welcoming from the moment you arrive, with room to enjoy today and endless potential for what it could become over time. Inside, original hardwood floors run throughout much of the home, while the comfortable 4-bedroom, 2-bath layout offers a sense of space that feels both functional and inviting. Every room reflects years of thoughtful care, creating a home that feels solid, lived in, and ready for its next chapter. At the heart of the home, an expanded dining room surrounded by walls of windows brings in natural light from every angle. It’s the kind of space that naturally becomes the gathering place of the home; morning coffee overlooking the yard, holiday dinners with family, or slow evenings spent lingering around the table with friends. Step outside and the possibilities continue. The backyard offers multiple spaces to relax, garden, entertain, or simply enjoy the privacy and peaceful setting. Perched above the home, a detached garage has been converted into a bonus space complete with its own deck overlooking the property below. Beneath it, an expansive workshop creates even more flexibility; ideal for storage, hobbies, a home gym, creative studio, or future ADU potential for buyers looking to maximize the property over time. This is the kind of home that sparks ideas the moment you walk through the door. Move right in and enjoy its charm exactly as it is, or slowly transform it into something truly special while building long-term value along the way.
