About 3505 Spring Street
(PORTFOLIO SALE) Combined portfolio 3411 Spring Street and 3505 Spring Street offered at $4,500,000. 3505 Spring Street is a unique 10-unit multifamily property in the heart of Paso Robles, offered at approximately $169,000/unit, $339/SF with a stabilized cap rate of 8.91% and annual rent upside of approximately $53,340. The property spans approximately 5,000 rentable square feet across two stories on a ±0.40-acre lot. The diverse unit mix includes five (5) studios with one bathroom, one (1) studio with two bathrooms, two (2) one-bedroom/one-bathroom units, one (1) one-bedroom/two-bathroom unit, and one (1) two-bedroom/two-bathroom unit — catering to a broad renter demographic. The property is zoned T-4NC and sits within a federally designated Opportunity Zone, providing meaningful tax advantages for qualifying investors. A RUBS program implemented in October 2025 per CA Civil Code §827 passes approximately 90% of gross utility costs back to tenants, materially improving net operating income. With current rents below market and one unit presently vacant, a new owner is positioned to immediately begin closing the income gap toward stabilized returns.
