The property has been well maintained with recent capital improvements, including new roofs and upgraded electrical panels. Select units have been enhanced by previous ownership with upgrades such as dual-pane windows, copper plumbing, updated water heaters, wall heaters, window A/C units, and improved flooring. Utilities are separately metered with 12 electric meters, 12 gas meters, and 4 water meters, providing operational efficiency for ownership. The property offers ample parking, including approximately 15 open spaces, a 1-car garage, and sufficient parking to accommodate all units and detached homes. Glendora is known for its strong community appeal, and highly rated school district, making this an attractive location for long-term tenancy. This is a rare opportunity for investors to acquire a stable, income-producing asset with upside potential in a prime location.
