The vacant unit allows for immediate occupancy while generating income from the remaining units. The property includes a 3-car garage with one vacant parking space available for a new tenant or owner. Additionally, each unit has their own private storage shed. Each unit is separately metered for gas and electricity, and has in-unit washer and dryers. Recent capital improvements enhance both the condition and long-term reliability of the asset.

Additional upgrades include new exterior paint within the past few years, a full copper re-pipe for all units, and replacement of the main water line in October 2009 per city permit records.
