About this home

Rare 1.45-Acre Development Opportunity in Prime Santa Ana Location! Exceptional oversized lot—hard to find in the heart of Santa Ana—offering endless potential for developers, investors, or owner-users. Ideally situated near the intersection of Main Street and McFadden Avenue, with convenient access to major streets and surrounding amenities. This expansive 1.45-acre parcel features two existing homes in need of TLC, providing the option to renovate, rebuild, or redevelop. The large, flat lot presents a rare opportunity for potential subdivision or development of multiple units (buyer to verify with city). With its generous size, the property may also be suitable for special-use projects such as a church, temple, or other community-oriented facilities (subject to city approval). Enjoy a massive backyard area with ample space for expansion, parking, or future improvements. Opportunities like this are extremely limited in such a central and desirable location. Don’t miss this unique chance to secure a large parcel with incredible upside potential!
