And realize once a pipe bursts, foundation settles, HVAC goes out, roof needs replacement, tenant stops paying and ruined the carpet and walls, appliance goes out, pest control for rodents and squirrels out of the attic, landscaping dies because tenant doesn’t water or take care of it, window breaks, house catches on fire because a dryer overheated, tree limb falls causing damage to a roof, plumbing leaks inside walls of the house and the list goes on.
