This exceptional offering comprises four contiguous parcels totaling approximately 20.5 gross acres within the prestigious San Marcos Farms community — one of the last large, undeveloped landholdings in the neighborhood. Nestled in unincorporated San Diego County, the property enjoys the character and open space of a rural estate setting while remaining minutes from the City of San Marcos’s retail, dining, and top-rated schools. The gently rolling terrain provides sweeping hillside views and abundant potential for a private equestrian estate, custom ranch compound, or residential subdivision (subject to County approval). The property conveys with nine (9) pre-paid 5/8” water meters and one (1) 1.5” water meter — a significant infrastructure advantage reducing future development costs. Situated in the San Marcos Unified School District attendance area and served by the Valley Center Fire Department, 1655 Marilyn Lane presents a rare opportunity to acquire a large, amenity-rich parcel in one of North County San Diego’s most sought-after rural communities.
