Answer from: Black Ops Chick
Not a hideout but a helpful tip. When you are at the Green house or the Yellow house stand in front of the door and look to your side, there will be a (If you are at yellow house) wooden wall, or (If you are at green house) a white wall. Go to the other side of the wall and climb onto the flower garden. Once you are on the garden, face the white or wooden wall and climb it like a ladder. Then you will be on the balcony and you can shoot people or climb in the window and stay in the house. Hope it helps. :)
