About this House

Income-Producing Duplex in the Heart of Newlands!

Located in Boulder’s highly sought-after Newlands neighborhood, just steps from the foothills, 415 & 417 Alpine Avenue presents a rare opportunity to own a well-maintained duplex on a quiet, tree-lined corner lot. With a strong rental history, timeless charm, and unbeatable outdoor access, this property offers both lifestyle and investment appeal.

The main-level unit is a spacious 4-bedroom, 2-bath home featuring hardwood floors, a bright kitchen with ample cabinetry, a cozy fireplace, and built-in storage. Natural light fills the space, and a fully fenced front yard enhances its outdoor living potential.

The lower-level unit offers 2 bedrooms and 1 bath, with a private entrance and optional interior access to the main unit. Both units feature full kitchens, shared laundry facilities, and generous parking accommodations.

Enjoy a two-car garage, and a large lot with a deck ideal for relaxing or entertaining—all with sweeping views of Mount Sanitas. Mature trees, lush landscaping, and space for gardening add to the home’s serene, outdoor-friendly setting.

Outdoor enthusiasts will love being just blocks from Mount Sanitas trailheads and the Dakota Ridge loop, with quick access to panoramic hikes. The property is also conveniently close to the Pearl Street Mall, CU Boulder, and the Ideal Broadway Shops.

Located within the top-rated Boulder Valley School District, the home appeals to families and renters alike. Plus, the arrival of the Sundance Film Festival to Boulder in 2027 is expected to draw over 70,000 visitors, creating even more short-term rental potential.
