Your next home rental agent may be a robot

There was no one home when Avisheh Madani arrived to tour a San Francisco rental property. No one human, that is. Madani, 35, used a code from an app to unlock the door and was greeted immediately by a robot. "It was definitely weird," she said. The robot, really a moveable video monitor, is the brainchild of Zenplace, a rental management company based in San Francisco and expanding quickly across the nation.
