Shoot...house dealings are never easy. We got taken badly when we bought our house. All the foundation damage was covered up with new walls and paint. Windows were re-positioned, doors re-hung. Then 6 months later the house started falling apart. We had cracks and separations from the wall-ceiling that were bad everywhere. The worst was in our bedroom where you could push a briefcase through the gap between the ceiling and the wall. It was at this point we understood the relationship of sellers, agents and even home inspectors. Those three f*s took us for a huge ride. We were young and dumb and ready to pick like low hanging fruit and they took full advantage of us. Knowing what I know now, and I'm not licensed to inspect a home, I can walk into a house and tell you if the foundation is bad. Looking back, we should have sued the living hell out of all of them but we didn't have the means too. Instead $45K and 10 years later, we had foundation piers put in throughout the house. Most of them internal. Guess how they put those in! Yep, tear every damn thing to pieces and bust through your foundation with jack hammers. We had about 20 of the internal piers done and probably 30 along the edge of the foundation.
My only consolation is that the former homeowner that took us for a ride died of massive heart attack 2 years after screwing us. Fortunately he kicked over before I could hunt him down. I had day-dreamed of knocking him off there for a few years I was so pissed off at what they did to us.
