About This Home
As of July 2026dr Exceptional Development Opportunity | Fully Rebuilt Multi-Unit Estate on Expansive Corner Lot Rarely does a property offer this level of versatility, income potential, and future development opportunity all in one beautifully curated package. Situated on an expansive 1/3-acre corner lot directly across from a beautiful park, this completely rebuilt property was thoughtfully redesigned from the ground up in 2021 and presents a truly unique opportunity for investors, developers, multigenerational families, or owner-occupants seeking long-term upside. The main residence is a stunning single-story 4-bedroom, 3-bath home featuring a spacious open-concept layout, beautifully upgraded finishes, designer staging, and an ideal split-bedroom floorplan with the private primary suite tucked away from the secondary bedrooms. The heart of the home is the expansive kitchen and living space designed for seamless entertaining and comfortable everyday living. Attached on the opposite side of the oversized two-car garage is a private 1-bedroom, 1-bath accessory dwelling unit currently generating approximately $2,000 per month in rental income, creating immediate cash flow and incredible flexibility for extended family, guests, or tenants. What truly sets this property apart is the extraordinary development potential. With the ability to add approximately 5,000 additional square feet of living space, this property offers a rare opportunity to significantly expand the existing footprint and maximize future revenue potential. The oversized corner lot features multiple gated access points, creating the ideal setup for additional units, separate entrances, private outdoor spaces, and substantial parking for RVs, boats, toys, or future tenants. Whether you envision a luxury multigenerational compound, an income-producing investment portfolio, or a future development project, the possibilities here are endless. Centrally located near major freeways, shopping, dining, and directly across from park space, this is a one-of-a-kind property combining lifestyle, location, and long-term investment value.
