Opening home details…
A rare find: two fully detached homes on one lot in the heart of San Pedro—perfect for income, multigenerational living, or both. The front home, 623 W 18th Street, is a classic Spanish-style with white stucco, clay tile roof, and a spacious 3-bedroom, 2-bath layout with wood floors, a functional kitchen, and a bright living area. The private, fenced backyard is ideal for relaxing or entertaining, and the basement offers valuable extra storage. A detached two-car garage and a newer roof (installed in 2018) complete the home. The rear home, 621 W 18th Street, built in 2007, offers a 2-bedroom, 2-bath layout with a walk-in closet in the primary suite, in-unit laundry off the kitchen, and gated two-car covered parking for added security and convenience. Each home has a separate entrance, outdoor space, and is fully fenced for privacy. Both are separately metered for gas, electricity, and water—streamlining management and expense tracking. Whether you're looking to live in one and rent the other, house extended family, or expand your investment portfolio, this well-maintained duplex delivers flexibility and long-term value in one of San Pedro’s most loved neighborhoods. Just over one mile from Cabrillo Beach and only one mile from the highly anticipated 42-acre West Harbor development—a future hub for waterfront dining, shopping, and entertainment—this property offers both lifestyle and investment upside.

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.
No earlier records were returned by our current sources. This does not mean the home has never sold.
