Multifamily Property For Sale · 10 Units

Investment Highlights

  • Available as a portfolio with neighboring 1127 12th St for additional income-producing units
  • Significant recent capital improvements reducing immediate capital expenditure
  • Redevelopment potential with RH-5 zoning, prior approvals, and design precedent
  • Leased to fraternity chapters with organizational lease guarantees.
  • Chronic supply-demand imbalance supports consistent absorption and annual rent escalations
  • Predictable cash flow driven by strong tenant pipeline and stable occupancy trends

Executive Summary

Positioned in the heart of Boulder’s University Hill, this property represents a rare investment opportunity in one of Colorado’s most supply-constrained rental markets. University Hill is geographically landlocked and effectively built out, with restrictive zoning and topography that sharply curtail future development, ensuring the enduring value of existing assets. This property is available as a portfolio with the neighboring student housing property for a portfolio price of $7,624,800.
CU Boulder enrolls more than 38,000 students and continues to experience an on-campus housing shortfall, making The Hill the first submarket to achieve full occupancy each leasing cycle. Both properties benefit from organizational lease guarantees through fraternity tenancy, providing financial stability and reducing turnover risk.
Ownership has invested in recent capital improvements, including upgrades to interior finishes and mechanical systems, limiting near-term capital exposure for new ownership. The properties also present compelling future upside through a redevelopment program supported by RH-5 zoning and prior architectural studies indicating potential for 14 to 19 additional bedrooms on the combined site. Boulder’s favorable 2025 zoning amendments and an existing Landmark Alteration Certificate further mitigate entitlement risk. This portfolio offers predictable income, programmed rent growth, and premium positioning within an irreplaceable student-housing corridor steps from CU Boulder’s vibrant social and retail hub.
