You CAN make some pretty good money actually. I have owned lease back airplanes before and made some money. I also lost money on a PA-28R. I owned a 172M that made me probably about 20K clean over the course of a year.
If you get a good later model 172S, you can clean up at the right flight school. I wouldn't do it with a 70's model again because parts are becoming more expensive and harder to come by. Also, the airframes are very high time. I sold mine for what I paid for it because I sold in the right market. 172S models stay on the market for 24 hours usually so you have to really be ready to buy one.
That is what insurance is for. Also, you should LLC that airplane. Never have your personal finances attached to it. The can sue Goonie LLC all they want, but nothing is there to take.
LLC doesn't provide protection against tort claims - and if the suit is on negligence grounds, my understanding is that you can't shield yourself with an LLC.
