Hi, newbie here - I have a house built in 1955 -it is a "front-to-back split", see attached. It is not at all level, the front is lower than the back - all furniture and appliances have to be "leveled" or you feel like you are going to fall out of bed.(as much as 2 or 3 inches from one side of a full-sized bed to the other!) I have just lived with it to this point, is this worth jacking up and leveling? Even if I did, the finished basement would still be off level as it it part of the foundation..? Any and all advice appreciated!
