Converting marijuana grow house back to normal

[Radin Mirshahi]

Hello BP. When buying a previous MJ growhouse SFR, what would be some things to look out for? I'll be looking at a property with the basement FORMERLY used as a growhouse. From the pictures, all the equipment has been ripped out and looks like a "clean slate" inside. Basement is concrete slab and partially finished. I read an article warning about possible illegal wiring, plumbing, bad sewer, rotting floor and danger of mold. But any other issues may I run into that I haven't mentioned yet? Any gotchas with insurance, hard money loans, laws and the like that you know of from experience? Finished product is to be a properly rehabbed standard SFR and marketed as such. Thanks in advance for any insight and lessons learned!
