I did sheet aircraft metal work for 15 years and I feel your pain. Damned miserable hot-ass hangar in the summer, frigid and numbing cold in the winter, subjected to zinc chromate primer, MEK, and lot of other healthy substances not to mention jobs that were always over budget, behind schedule and as a result, had to work a lot of weekends.
Thinking I wanted to remain in aviation, I pursued a career in mechanical engineering while I continued to work full-time. I was over halfway there to my BSME but couldnt get past the upper level engineering classes. During my education I was exposed to PC's. I taught myself PC's and networking, and eventually started a part time business consulting. I finally crossed over into information technology about 6 years ago and never looked back. I wear nice clothes to the office, am in a climate controlled data center, and am making more $ than I did back then.
I'm sure there are lots of individuals happy in the aviation maintenance field and I am not taking anything away from that but for me, it was the smartest move I ever made.
I can't comment on your real estate possiblities but you are smart to be wanting out. Stick with it and keep looking. Good luck
