Welcome to this spacious 5-bedroom, 3.5-bathroom home offering 3,306 square feet of living space on an expansive 18,295-square-foot lot in Riverside's desirable Arlington neighborhood. Filled with natural light, this home features a grand foyer with soaring ceilings, an elegant staircase, and oversized windows. The main level offers both a formal living room and family room with a cozy fireplace, providing multiple spaces to relax or entertain. A private main-floor bedroom with a full bathroom is perfect for guests or multigenerational living, while a separate powder room adds convenience for visitors. The spacious kitchen opens to a dining area and is complemented by a versatile flex room that can serve as a formal dining room, home office, library, or playroom. An additional bonus room between the garage and main-floor bedroom provides even more flexible space for a gym, hobby room, workshop, game room, craft room, or storage. French doors from the living areas provide seamless access to the backyard while showcasing beautiful views of the oversized lot. Upstairs, a cozy loft overlooks the grand foyer below, creating the perfect reading nook or sitting area. Three generously sized secondary bedrooms share a full guest bathroom, while the spacious primary suite features its own ensuite bathroom. Outside, a large circular driveway provides abundant parking, while gated side access to the backyard offers room for RVs, boats, trailers etc. The expansive backyard features a spacious covered patio with an oversized concrete entertaining area, perfect for BBQs, gatherings, or relaxing outdoors. Beyond the patio, the nearly half-acre lot is a blank canvas waiting for your vision—whether it's a resort-style pool, outdoor kitchen, lush landscaping, or the backyard retreat you've always imagined. Several of the main living areas have been refreshed with fresh interior paint, including the grand foyer, formal living room, family room, kitchen, dining area, and upstairs hallways. Additional improvements include a roof replacement and two newer A/C units, both completed approximately three years ago. With 5 true bedrooms, two additional flexible bonus spaces, an oversized lot, abundant parking, RV access, and endless possibilities both inside and out, this is a rare opportunity to own a home with space, versatility, and room to grow in one of Riverside's established Arlington neighborhoods.
