No one has had crack cooked in their house?!!
why not call some local remediation companies for an opinion on a upcoming "project" you're interested in.
I have a bunch of Leo friends. I will ask around. I find it awesome you referenced Master P uuuughhhhhh!
I believe there are actually laws regarding how to handle a house (and the rehab) that was a drug lab. It probably varies by state. I want to say there is quite a bit to do as there are off gas from materials that have absorbed the chemicals in the creating process of drugs. Kind of like having to deal with asbestos, so probably $$$. Do some serious research before you buy this. Real serious research because since you now know the odds are 99.999% they cooked in there you are liable for anything after the fact. Personally I wouldn't touch it unless the price would allow me to bulldoze it and build new. Others might say it could be saved but I just don't want that hassle not matter the money. Again just my personal opinion as I have no experience dealing with it.
