Management covers what happens after you own a property. Across property management, rental management, running a real estate business and renovation, it explains how to improve occupancy, tenant satisfaction, repair planning and profitability. It gives owners and management companies practical know-how for on-the-ground issues such as reducing vacancy, handling move-out restoration and long-term repairs. It reflects lessons from managing 400-plus units in our own operations.
