The Unique Apartment Group is pleased to present 1127 12th Street, a 12-bed, 4-bath student housing investment on University Hill in Boulder, Colorado, steps from the CU Boulder campus and The Hill's retail, restaurant, and bar corridor. The property is currently leased to a fraternity as its main house, providing an organizational lease guarantee and a built in occupancy pipeline through the chapter's recruitment cycle. Annual rent step-ups are the submarket norm, and the group lease configuration reduces turnover friction for a stabilized, hands-off cash flow profile.Ownership has invested meaningfully in recent years, minimizing near term capital exposure for a buyer: the exterior deck was replaced with Trex decking in 2024, two bathrooms were fully remodeled in 2025, and a $120,000 interior modernization was completed in 2026, including a full electrical and panel upgrade, drywall replacement, fresh paint, and general maintenance.Beyond in-place cash flow, the property offers long-term development upside. Zoned RH-5 (Residential High Density) on a lot, it benefits from Boulder's 2025 zoning amendments eliminating parking minimums, minimum land area per dwelling unit, and occupancy limits. A 2020 Landmark Alteration Certificate for rear additions sympathetic to the historic 1899 structure established design precedent with City staff and the Landmarks Design Review Committee, though that approval has expired and would need refreshing. Inclusionary housing requirements and Landmarks review remain part of the entitlement path, but the zoning framework and prior design work give the next owner a clear runway to expand density.

Set beneath the ancient sandstone walls of Eldorado Canyon, this extraordinary modern alpine estate was designed by acclaimed architect David Biek, built by master builder Kevin Cowan, featured in Colorado Homes and Lifestyles magazine, and televised on the Lynnette Jennings Show. Exceptional stonework, patinaed copper, rich hickory and beech floors, & soaring ceilings make the architecture feel alive with intention - a home that belongs to its canyon as completely as the ancient rock above. Step inside: radiant-heated floors underfoot, canyon light flooding through enormous windows. Two stained glass windows bracket the day - morning light pours across the great room wall at sunrise; the west-facing sunset window in the solarium off the crafting loft closes the day in warm color. Three bedrooms, two full baths, & powder. Carlos Steybe's cherry millwork fills every turn. The great room's soaring 25-foot stone fireplace commands the space; the family room hearth burns wood. The chef's kitchen: floor-to-ceiling pantry, Sub-Zero, dual Wolf ranges, Bosch dishwasher, built-in cherry breakfast table. The dining room holds a Steybe-built table and chairs alongside his cherry hutches. The third-floor sanctuary: beech floors, walls of glass, two private patios to the canyon - office, meditation room, or yoga studio. The owner has kept bees on the roof, where the air is clean,& the world falls quietly below. Walk the labyrinth at dusk - plumbed for water and gas, awaiting your vision of fire & flow. Harvest from the biodynamic garden, entertain in the outdoor kitchen, soak in the hot tub under a wide Colorado sky. Eldorado Springs water flows to every faucet & shower. An ancillary building houses the wine cellar - vendange table, bench seating, 3,000+ bottles behind artisan copper doors - & a recording studio with acoustic baffling & beech floors. The non-conforming guest cottage, wood shop, open garden shed, & large storage shed complete this once-in-a-generation estate.
