We are currently renting our house and considering purchasing it from the owner, but it is sagging, and in some rooms it is rather significant and noticeable, with the worst parts being approximately a 1" rise in a 24" run. It has apparently been this way for a while, as all the owner's trim work has strange angles cut to fit the shape of the house.
There is a thick beam in the basement, probably 6" by 6" or greater, that crosses the entire house and supports all the joists. A four foot section was removed to put in the new furnace. I'm not sure if this cut is the reason the house is sagging, but I'm wondering if this amount of sagging is something to worry about, if we should look into fixing it and how hard of a fix it is likely to be, or if it's strongly suggested that we find another place.

A 1" to 16" slope is huge. that would mean a 10 " drop in apx 13 feet. Did you mean 1" in 16 feet? Regardless, the fact that you are asking the question indicates that you need a professional to take a look. There are many possible reasons from maybe the cut center beam, collapsing or crushing support posts(top or bottom), settled footings, etc. This is a common situation in very old houses, especially ones built on stone foundations. A simple answer would be to jack and support the offending beam(s) to restore a level floor, *however*several other factors need to be considered before jacking can be done. Factors like chimney/roof coupling, door and window reactions, tile floors, millwork/trim, plumbing connections........the list goes on. Find a competent general contractor that has experience working on older homes. That person should be able to determine the root cause, then formulate a plan to fix the problem. To buy the house or not might be determined by the repair costs and advise this person gives you. I would also have a complete home inspection done before even considering making an offer to buy this house.
