3140 21st Street presents a unique turnkey opportunity to acquire a well-maintained and actively managed 28-unit apartment building in San Francisco's Inner Mission District. Owned and operated for 14 years by a TIC partnership of brokerage and investment professionals, the property is being sold due to the conclusion of the partnership rather than asset performance. Built in 1927, the building includes three (3) studios, fifteen (15) junior one-bedroom units, ten (10) one-bedroom units, and twenty (20) parking spacesan exceptionally rare amenity for a property of this size and location. The apartments feature a mix of classic and updated finishes, including hardwood floors, bay windows, abundant natural light, spacious closets, and renovated kitchens and bathrooms. Despite active management and ongoing improvements, existing rents remain below market. Additional amenities include a large side yard, owner storage and workshop space, and shared laundry facilities. Many of the property's most substantial improvements are already complete, including Soft-Story seismic work, Fire Alarm Ordinance compliance, roof and window upgrades, and underground storage tank removal. The boiler and steam-heating system was removed by permit and replaced with baseboard electric heating, while gas and electrical service remain separately metered. Located at 21st and Capp streets, the property sits within the Mission District's growing AI and technology ecosystem, part of San Francisco's emerging Arena.'' Residents enjoy convenient access to Mission Bay, SoMa, Yerba Buena, the Financial District, and Potrero Hill, along with nearby dining, shopping, nightlife, public transit, and major freeways. The property is offered with assumable financing of approximately $3.2 million at a 4.4% interest rate with approximately 12 years remaining. One ownership partner may also be willing to roll a portion of their equity alongside a new owner or sponsor. With extensive parking, completed capital improvements, below-market rents, and attractive financing, 3140 21st Street represents a compelling long-term investment opportunity.
