My wife and I went to look at a cheap house. It's the right size of house in the right school district, has the right location, etc. I found out why it's so cheap. There are many issues with the house. Most are cosmetic. The basement floor and basement block walls all seem to be in decent shape aside from one crack in one corner. There are wall that are out of plumb, not square with the room throughout the house, etc. Drywall needs replacing, flooring, lots and lots of stuff. Almost overwhelming, but not quite. The thing that my decision to pursue or not is going to come from the one glaring issue I found. The previous owner cut a hole in the middle of the first floor to install basement steps. It has engineered joists. They were never supported properly. The first floor floors all tilt inwards toward that area. Some more than others. The roof line looks ok. The exterior walls look ok. My question is, how do i go about fixing the issue? I was under the impression that you cannot jack up under an engineered joist. Is this something that i can sister/plate the ends that need supported at the stairwell and put a beam and jacks under? The joists are the truss type, not the plywood composite center type. I am returning to the house tomorrow evening and will be able to upload a picture to better help with understanding. Thanks in advance.
