Multi-Family Home for sale in Boulder, CO

for $3,850,000. This home was built in 1899 on a lot size of 0.21.

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.
