Executive Summary
The property presents a compelling opportunity for investors seeking stable in-place income, value-add upside, and long-term ownership in a high demand and supply-constrained rental corridor. Henderson Arms Apartments is comprised of a desirable mix of 33-1bed/ 1bath and 6-2bed/1bth units. The units consist of a blend of updated and classic finishes, offering immediate rental appeal with clear upside through strategic renovations. Building features include double-pane windows, secured entry, private balconies, ample storage and common-area laundry facilities. The property also presents the potential for additional unit development with a largely unutilized full height basement, providing an attractive path to increase density and future income.
