Rehabbing a Meth Lab

[No Name]

I’m preparing to invest in an area that is known for having meth labs. The fact that meth labs are a problem in the area, buyers are not motivated to purchase. At the same time, prices are pretty good for a wholesaler or rehabber. My major concern is purchasing an ex-meth lab. I’ve been researching the internet for test kits. I would like to perform quick checks without having to bring the EPA on in every possible purchase. Does anyone have any suggestions? I’m looking for a pretty good inexpensive test kit that would allow me to find any residue which will help with my decision making. I would hate to deal with a property that would cause harm to an end user or my construction crew. Thanks.
