Opportunities like this simply do not exist in Downtown Flagstaff--especially not in newer construction. This duplex offers something incredibly rare: modern design, fee simple ownership, and true flexibility in one of the most supply-constrained locations in Northern Arizona. Each side features 3 bedrooms, 2.5 bathrooms, and a 2-car garage, with approximately 1,650 sq ft per unit of thoughtfully designed living space. Inside, you'll find open-concept layouts, high ceilings, abundant natural light, quartz countertops, stainless appliances, and sleek contemporary finishes that rival luxury downtown condos--without the limitations. Here's the real differentiator: A nearly identical building type just blocks away--classified as a condo--has commanded pricing around 1.1M for a single unit. Meanwhile, this property delivers TWO full residences on one lot. That means you're not just buying a home... you're buying control, flexibility, and long-term upside. Why this property hits differently: Live in one side, rent the other to offset your mortgage True investment property with two income streams (~3,250/unit potential) No HOA--unlike nearby condos with monthly fees and restrictions Fee simple ownership--you own the land, not just airspace Walkable downtown lifestyle--restaurants, shops, trails, NAU, and nightlife just minutes away New construction in a historic core--a rarity that cannot easily be replicated Whether you're an investor, owner-occupant, or someone looking to secure a foothold in downtown Flagstaff, this property delivers multiple exit strategies: long-term rental, short-term rental, or hybrid living. **** Owner/Agent
