Check with the townAny house electric?

Don't pay retail or clean up a sellers mess for free👍 

So far they seem to be receptive when I send a notice to clean something up, but everytime I check on the place, there's something outside that looks awful.

I'd assume I probably wouldn't want to send a crew of people to work on a meth house without having it cleaned up first, even if it was being gutted anyway. 

They left the items there for about two months and paid a $500 clean up fee for the items left behind.

The other inspection required the electrical to be updated.
