Welcome to 4214 Sinclair Avenue, a rare Rosedale property featuring a charming 3-bedroom, 2-bath bungalow plus a more recently constructed oversized 2-car garage with a beautifully finished 1-bedroom, 1-bath garage apartment. Built in 1937 in the first generation of Rosedale homes, this storybook home is filled with period charm, including a timeless brick exterior, wrought-iron front porch, hardwood floors, high ceilings, crown molding, abundant windows with wood shutters, and a beautiful fireplace.  The spacious living and formal dining rooms are ideal for entertaining, with the dining room showcasing a built-in period china cabinet and access to the side yard. The galley kitchen offers views to the living and dining areas, space for casual dining, and a convenient laundry closet with backyard access.  The generous primary suite features multiple closets and a wall of windows with built-in cabinetry below, creating a charming window seat with additional storage. Two spacious secondary bedrooms continue the home's classic character with hardwood floors and abundant natural light.  The private backyard offers stone pathways, a wood privacy fence, and access to the oversized garage with side street entry. Above the garage, the thoughtfully designed apartment is separately metered for water and electricity, making it ideal as an income-producing rental, guest quarters, multigenerational living, or a private office. The apartment features hardwood floors, a bright open living area, a well-appointed kitchen with island seating, built-in cabinetry, a spacious bedroom, full bath, dedicated laundry, and a private patio below.  A short two block walk to Ramsey Park/pool plus Central Market and other well known stores/restaurants and walking trails nearby.  A rare opportunity to own a property that perfectly blends historic charm with modern flexibility in one of Central Austin's most desirable neighborhoods.
