At the house, you can check the front door, back door, window, or garage. Searching the garage will net you a random tool. A zed will come by but can be avoided by hiding. Searching the window gives you some narration.
Entering via the front door starts you in the front room.
Entering via the back door starts you in the kitchen.
The front room can be searched for a random item. The kitchen has food to pick up. You must search the kitchen and basement before going to the bedroom or bathroom or you will miss the opportunity to pick up a gun and possibly two items or ammunition. The basement requires a light source to search. Once you get the items, you will have to fight a runner to leave.
Searching the bathroom results in a random item.
