Basement foundation advice?

Looking at buying a 50 year old brick ranch. I noticed the top of the basement concrete seemed pushed in and when I put a plumb from top plate to basement floor the top tips in 3 inches. They've put in some 2 x 8 steel wall brackets on the flat but they are also bowing. We have diagonal cracks and well as some horizontal cracks ANd quite a few cracks that are filled but have not re-cracked. Since they put those steel braces on I noticed the poles holding the center beams up are leaning 2+ inches as well and the beam is curved a little from end to end. So this indicates the whole house has moved. The inspector I had in saw all this and said that if we controlled the water runoff better that the house probably would not move much more and all seemed OK as it sits now. My fear is that everything is stressed so much now and you can notice the bend in the outside brick siding that just the slightest movement and everything will crack. So - should I run from this or do you think all is good?
