A carpenter I know made some decent money that way. Tenants at a local housing complex would sometimes tear up the place just for the hell of it. And often they would break open the walls to get at the copper pipe, then sell it to scrapyards.
Do they still use copper pipe? Anyway, he would come in and make repairs. Put in new copper pipe, fix the walls. Then the tenants would tear the up place again. Etc.
They shot Carpenters in Norfolk.
