Property Description

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
