FRONT HOUSE VACANT, CAN BE DELIVERED VACANT FOR OWNER/USER. Pleased to exclusively present the opportunity to acquire 547 William Street, a well-maintained four-unit multifamily property located in the City of Pomona, one of the San Gabriel Valley's established and steadily growing rental markets. The property consists of four spacious two-bedroom, one-bathroom units situated on a single parcel.
The property offers a distinctive and desirable layout, pairing a charming single-story, cottage-style front residence with three additional units at the rear. The front cottage carries the timeless character and quality craftsmanship of classic early-California construction built in 1907, while the rear units bring a more contemporary floor plan, built in 1979—giving the asset a rare blend of curb-appeal character and functional, tenant-friendly design. Most importantly, all four units have been fully renovated and modernized throughout, so residents enjoy the charm of the property alongside updated, move-in-ready interiors.
Recent capital improvements underscore the pride of ownership behind this asset, including new electrical panels installed in 2025 and extensive renovations across the units. The property has been held by the same ownership for more than 25 years, reflecting long-term care, stewardship, and consistent reinvestment. Each unit is equipped with central air conditioning and heating, with two HVAC systems recently replaced. Residents benefit from individually metered gas and electricity, individual hot water heaters, and select plumbing upgrades, including partial repiping in certain units. Additional amenities include an owned on-site laundry facility, providing both tenant convenience and supplemental income potential.
With a desirable all two-bedroom floor plan configuration, 23% rental upside, recent capital improvements, individually metered utilities, and strong rental fundamentals, 547 William Street presents investors with an opportunity to acquire a stabilized multifamily asset offering both immediate income and long-term appreciation potential within a supply-constrained Southern California rental market.
