5185 Santa Clara Place is a four-unit multifamily property in Boulder’s established Keewaydin neighborhood — a rare opportunity to own in one of Colorado’s most tightly held and institutionally dominated rental markets at an accessible basis. Where most Boulder multifamily trades at scale and out of reach for private capital, 5185 offers direct ownership with a clear value-add path through continued unit renovations. With immediate access to Foothills Parkway and Baseline Road, the property serves a deep, self-renewing tenant pool of University of Colorado students and young professionals. As new ground-up development pushes rents higher across Boulder, well-maintained existing product like 5185 stands to capture that lift at a fraction of the basis. Boulder has proven one of the most durable real estate markets in the country, with resilient rental performance and sustained appreciation through multiple cycles.

The Unique Apartment Group is pleased to present 1012 14th Street, a 16-bedroom, 5-bathroom student housing investment property on University Hill in Boulder, Colorado. Steps from the CU Boulder campus and the retail, restaurant, and bar corridor that defines The Hill, the property sits in the most coveted student rental submarket in the state. Students gravitate to The Hill for the social scene and walkability, and demand consistently outpaces supply: University Hill is geographically landlocked and effectively built out, with zoning and topography that sharply limit new construction, while CU Boulder enrolls over 38,000 students against a persistent on-campus housing shortfall.The Hill submarket operates on a pre-leasing cycle: next year's leases are typically executed during the prior fall semester, giving ownership rare forward visibility into occupancy and rental income before the current term rolls. 1012 14th Street is currently leased to fraternity members, providing organizational lease guarantees and a built-in pipeline for future occupancy through the chapter's recruitment cycle. Annual rent step-ups are the submarket norm, and the 16-bed, 5-bath configuration suits the group lease model, reducing turnover friction and delivering a stabilized, hands-off cash flow profile.Ownership has also invested meaningfully in the asset over recent years, leaving a new buyer with minimal near-term capital exposure: in 2023, all bathrooms and the basement kitchen were renovated, the roof received extensive repair and shingle replacement, and new modified bitumen was installed on the flat roof section; in 2024, the PRV and expansion tank were replaced; and in 2025, interior paint and flooring were refreshed throughout.

Hill Yeah! When it comes to student housing, few areas work harder than University Hill. This well-maintained duplex with one very lively backyard sits steps from CU Boulder's campus and every Buffs game, class, and Friday night the calendar can offer. 2026-2027 projected NOI: $82,320. That's the kind of number University Hill produces year after year, thanks to a tenant pool that basically renews itself every August. Buy the duplex. Ride the schedule.

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.

Two separate residences on one lot! Pre-leased through July/August 2027. Well maintained and professionally managed for 30+ years. 741-743 19th Street presents a turnkey, recession-proof asset in the city's most lucrative rental pocket. Rare Double-Income Layout: Unlike standard single-family homes, this property features two separate houses on one lot, packing 7 bedrooms and 4 bathrooms into a single parcel. Proven, Low-Risk History: With a 30 year track record of uninterrupted rental history, the property has a proven blueprint for success, making it an easy addition to a portfolio or a perfect asset for a 1031 tax-deferred exchange. Professionally managed for decades with 100% Occupancy rates with an almost endless supply of renters year after year! While other real estate investments suffer during economic downturns, student housing directly adjacent to a major university like CU Boulder can be a defensive asset. Because the property packs 7 bedrooms across two separate houses on one lot, you are purchasing a high-density rent engine in a premium zip code where strict local zoning laws prevent competitors from building new multi-family structures. Essentially, you are buying a scarce piece of real estate with a captive consumer base! 48-hour notice for showings.
