The property currently generates $5,543/month in gross rents, but make no mistake — that number tells only half the story. With units priced well under prevailing market rents in the Harbor City area, a savvy buyer has immediate runway to close the gap and dramatically boost NOI. Bring rents to market and this property performs at a 7% CAP rate — exceptional for the Los Angeles South Bay market.
Spanning 3,551 sq ft across 9 bedrooms and 4 bathrooms on a corner lot, this well-maintained quadruplex offers the scale to move the needle. Four garage spaces add a premium amenity that commands top-of-market rents and reduces vacancy. In-unit laundry hookups in each unit further strengthen the rental appeal.
Harbor City’s fundamentals back up the upside. A Walk Score of 87 means tenants aren’t going anywhere — strong walkability drives demand, limits vacancy, and supports rent growth over time. With schools, shopping, and transit all nearby, this location consistently attracts quality, long-term renters.
