Properties offering this much land, privacy, and versatility in such a desirable location are becoming increasingly difficult to find. Welcome to 5605 Archibald Avenue, a unique property combining spacious living, extensive improvements, and exceptional possibilities for the future. The home features numerous upgrades, including copper plumbing, smooth-finish drywall, dual-pane windows, a 200-amp electrical panel, upgraded insulation, and a newer water heater installed in April 2026. All air-conditioning units and ductwork were replaced in 2016, providing additional comfort throughout the home. Inside, you'll appreciate thoughtful details such as cedar-lined closets, marble-top vanities, ceiling fans, and a Jacuzzi-brand tub. The kitchen is equipped for serious cooking and entertaining, featuring professional-grade appliances, including a 48-inch double oven, a professional 30+30 inch refrigerator, and a kitchen island already plumbed for water and power. The property also offers impressive utility and functionality, including an expanded septic system, a 500-gallon owner-owned propane tank, a 220V/30-amp garage outlet, washer and dryer hookups in both the garage and laundry room, and a generous 20-foot-wide RV driveway.
