Remarks

3173-3173A 21st Street is a 4-unit property featuring 3 residential apartments (1) 1-bedroom 1-bath plus den unit, (1) 2-bedroom 1-bath and one (1) spacious 4-bedroom, 2-bath unitalongside an ADAcompliant ground-floor commercial space that is being operated as a hair salon and is leased at $2,799.00 per month on a 3-year lease that was signed in October 2025. There's a shovel-ready 1-bedroom ADU on the ground floor that awaits finishing by a future owner, offering additional income potential once completed. With the existing units brought up to market rents and the ADU finished, there is approximately 60% upside in the current rent roll. With separate individual water meters, new 400 amp electrical service, the property benefits from extremely efficient operating expenses, making this an attractive opportunity for an investor seeking both stable income and growth potential.
