(More pictures coming soon) Welcome to four thousand five hundred twenty-one 3rd Avenue Northwest - a truly rare five-acre estate in the highly desirable Collier Woods area, west of nine hundred fifty-one (Collier Boulevard). Opportunities like this rarely hit the market, especially with this combination of land, income potential, and infrastructure. The main residence offers over two thousand seven hundred square feet of living space and has been thoughtfully updated with new tile plank flooring, a new Samsung refrigerator (2024), new Samsung washer (2024), upgraded electrical service with whole-house surge protection, and recent pool repiping in 2025. A wind mitigation report with third-nail reinforcement adds additional peace of mind and potential insurance savings. In addition to the main home, the property features a separate apartment building with two private one-bedroom units totaling over one thousand four hundred square feet of living space. Beneath the apartments is a four-car garage, creating exceptional flexibility for rental income, multigenerational living, or guest accommodations. For those needing serious storage, workspace, or commercial-grade capability, the massive forty by sixty hurricane-rated metal outbuilding is a standout feature. Complete with a car lift and built for durability, this structure is ideal for collectors, contractors, boat or recreational vehicle storage, or hobbyists. The building is equipped with two hundred twenty-volt service throughout, multiple two hundred twenty-volt outlets both inside and outside the garages, two dedicated electrical panels, and weather-tight exterior outlets on the balcony posts. A water hydrant sits outside the building, and irrigation and electrical lines run along the driveway and across the front of the property ending in an additional hydrant at the west property line - providing exceptional utility flexibility rarely found in residential properties. All structures feature metal roofs for long-term strength and storm resistance. Situated west of nine hundred fifty-one this location provides the perfect balance of privacy and proximity - inside a rated school district and just minutes to the new Mason Classical Academy being built; medical facilities; shopping; dining; and everything Naples has to offer. Five-acre parcels in Collier Woods are exceptionally rare. Add in over four thousand one hundred total square feet of living space; income-producing units; extensive garage capacity; high-capacity electrical infrastructure; and premium location - and you have a property that truly stands apart. This is more than a home - it's a compound designed for flexibility; income; and long-term value.
