Overview

Welcome to 521-523 Belle Avenue, a well-maintained San Rafael duplex offering an excellent opportunity for investors, owner-users or buyers seeking a flexible multi-unit property in a convenient Marin County location. Each of the two units features a comfortable 2-bedroom, 1-bath layout with updated kitchens, functional living spaces and a warm, inviting feel. Both residences are currently tenant occupied, providing immediate rental income and making this an appealing option for those looking to add a solid income-producing property to their portfolio. The thoughtfully updated kitchens bring a fresh, modern touch to each unit, while the efficient floor plans offer comfortable day-to-day living. Onsite laundry and additional storage are located in the basement, giving residents convenient access to practical amenities that are often difficult to find in smaller multifamily properties. Each unit also includes its own designated space in the carport, adding valuable off-street parking and everyday convenience. Outdoor space is another standout feature of the property. A generous shared common area creates a welcoming setting for barbecuing, outdoor dining, entertaining or simply relaxing in the Marin sunshine. A separate garden area offers room for residents to grow flowers, herbs or vegetables, creating a sense of community while still allowing for distinct uses of the outdoor spaces. Ideally situated near Dominican University of California, this duplex is close to shopping, dining, everyday services and many of the outdoor destinations that make San Rafael such a desirable place to live. China Camp State Park is nearby for hiking, biking and exploring the bayfront, while McNears Beach offers opportunities for picnics, recreation and time by the water. The property also provides convenient access to downtown San Rafael, local transportation routes and surrounding Marin communities. With two updated, currently rented units, onsite laundry and storage, covered parking and inviting outdoor areas, 521-523 Belle Avenue combines functionality, income potential and a sought-after location. Whether you are looking for a long-term investment, a future owner-occupancy opportunity or a versatile property in the heart of San Rafael, this duplex offers a compelling blend of comfort, convenience and value.
