520 SW 4th Ave is a beautifully maintained and extensively updated single-story rambler in one of Oak Harbor's most established and sought-after residential neighborhoods. Located just 0.2 miles from Broadview Elementary and minutes from shopping, dining, NAS Whidbey Island, and the breathtaking beauty of Deception Pass, this property offers the complete Whidbey Island experience. A lush, fully landscaped yard, fresh exterior paint, and classic wood-product siding create an inviting first impression. Inside, you'll discover a thoughtfully designed 1,510 square-foot floor plan that lives large, offering two generously sized bedrooms, two updated bathrooms, and an expansive family room. The living room showcases durable LVT floors and an open, airy feel, and the formal dining room flows seamlessly from the kitchen, which features a gas range, oak cabinetry, and included appliances. The flooring is fully updated with LVT, ceramic tile, vinyl, and new carpeting. The oversized primary bedroom is a true retreat, complete with a private ensuite bath and direct access to a serene, fenced back patio. Major improvements by the current owners include a new composition roof, all-new attic and crawlspace insulation, modern interior doors, and a highly efficient mini-split HVAC system providing year-round heating and air conditioning. Additionally, low-voltage wiring and outdoor camera hookups have been installed for home security systems.
