Back in the mid 80s I was building the house I live in now and was the victim of arson. Luckily, I had not moved any personal stuff in … the electrical inspection was still 3 days away.
Insurance paid for the clean up, and replacement materials … but it was very depressing. I had spent so much time trying to finish it … often after work + dinner I would come over with a Coleman lantern and do a few hours of work.
When it came time to re build, I almost had trouble doing it … in the back of your head there is a fear it will be taken away again … it was tough to overcome, but luckily I got it done and I still live here.
Best of luck with it, I know what it is like!
