Property is being offered via auction. Exceptional and truly rare 4-unit investment opportunity in the heart of Westminster. 7781 15th St. is a charming and uniquely configured multi-generational property showcasing pride of ownership and long-term stewardship. Situated on an expansive 11,326 sq ft lot, the property features a highly desirable unit mix: a detached 2-bedroom/1-bath single-family residence built in 1928, along with a rear triplex constructed in 1987 consisting of three spacious 2-bedroom/2-bath units. The front residence exudes timeless character and craftsmanship, highlighted by original solid-core doors and hardware, coved ceilings with detailed molding, a formal dining room, and wall-to-wall carpeting preserving the hardwood flooring beneath. The home enjoys a large private front and side yard, dedicated parking pad, and excellent separation from the rear units—ideal for owner-occupancy or premium rental positioning. The rear building offers well-designed layouts with strong tenant appeal. Unit B (ground level) features three sets of sliding glass doors opening to an expansive wraparound patio and yard space, creating a unique indoor-outdoor living experience. Units C and D are located upstairs and benefit from elevated positioning with open views across the property from the living and dining areas, as well as private patio spaces. Units B and C have been remodeled, enhancing overall condition and rental upside. All four units include detached garages, washer/dryer hookups, and individual water heaters. The rear units are equipped with forced air heating and central air conditioning. The property is separately metered for gas and electricity, offering efficient management and reduced landlord expense exposure. A massive concrete driveway provides abundant off-street parking in addition to the four garages. The asset presents a compelling value-add opportunity, as current rents are significantly below market with immediate and attainable rental upside. Ideal for investors, 1031 exchange buyers, or owner-users seeking long-term appreciation and income growth in a strong rental market. Conveniently located near major thoroughfares, shopping, dining, and employment hubs, this property combines historical charm, functional unit mix, and future income potential—making it a standout investment in one of Orange County’s most established communities.
