Pleased to present 524 Williamson Avenue, a 7-unit investment opportunity located in Fullerton. This property was built in 1961 and is being offered for the first time in over three decades. With 6 out of the 7 units configured as spacious two-bedroom layouts, the property offers an excellent unit mix ideal for long-term growth and strong tenant demand. The property underwent a complete re-pipe in 2016 with durable and efficient PEX piping as well as a full roof replacement in 2025 (excluding the garages), significantly reducing future maintenance concerns. An onsite laundry facility, though currently unused, offers the opportunity for additional income. Select units feature private yards and ceiling fans, enhancing tenant comfort, while the property also includes garages and onsite parking spaces, a desirable amenity in the area. Currently listed at just $256,429 per unit and under $300 per square foot, this asset represents a compelling value play with over 196% upside in rental income, providing a clear path for substantial value-add potential. This is a rare chance to acquire a legacy asset in a strong rental market, with attractive fundamentals and outstanding potential for repositioning and long-term returns.

No weekly rateNo published rate within 7 days of this date.ZIP averages use publicly displayable closed sales from our licensed MLS feed, matched to the same ZIP and exact property type. Months with fewer than 3 sales are omitted; the current month is incomplete. Lines connect available monthly observations across gaps and do not represent measured prices in missing months. These averages are not adjusted for size, condition, or location within the ZIP, and are not an appraisal. Feed coverage may not include every sale. All available shows the available home and ZIP history, with mortgage rates over the same dates.
Mortgage benchmark: Freddie Mac Primary Mortgage Market Survey®. © Freddie Mac. Weekly national 30-year fixed rates, not APRs or a loan quote. Actual terms vary. Methodology changed in November 2022. The chart does not establish that interest-rate changes caused a home’s price changes.
Lines connect recorded asking and sale prices. They are visual guides, not estimates of the home’s value between those dates.
