CASH ONLY Welcome to 5451 Moonstone Avenue, a rare and exciting opportunity in the heart of upper Rancho Cucamonga. This mid-century modern home, originally built in 1958, embodies the stylish architecture of its era and is waiting for the right visionary to bring it back to life. The home, situated on just under 1.5 acres of prime, equestrian-zoned land, offers unparalleled privacy and breathtaking mountain views. Tucked away behind three homes that front Hillside Road, this property provides a serene retreat while still being close to everything Alta Loma has to offer. The lot is predominantly flat, offering the perfect canvas for your dream home or homes. The existing single-level structure has been gutted, with the demo already done, allowing you to start fresh with your renovation plans or develop an entirely new estate. Mature citrus and fruit-bearing trees dot the landscape, enhancing the natural beauty and charm of this expansive parcel. The previous owners have even drafted preliminary plans for a secondary structure on the western portion of the lot, offering even more potential for customization. This is more than just a property; it's a piece of history, a chance to revive a mid-century gem, and an opportunity to create something truly extraordinary. Whether you choos
