Unscrupulous tenants have been known to turn on appliances and leave them running, turn on faucets and leave them running, turn on lights and leave them running, turn up the heat and leave it running, remove smoke detectors, unleash pests (insects/rodents/etc) in the property, and worse.Fifth, see if your situation meets the criteria for abandonment, for your jurisdiction.
