Drug lab house liabilities

My husband and I are beginning real estate investors. We have found a bank-owned house that apparently was used to manufacture some kind of drugs (can you say meth lab?) - a/c has been rerouted, weird holes in the walls, ductwork all over the place - its a mess!. We are considering buying it and fixing all the damage done to the house by the former owners and reselling or lease optioning it, but need to know how to go about confirming that no damage/contamination was done to insulation, etc. In addition to just wanting to do the right thing, we don’t want to be sued later because some buyer down the road gets sick and blames it on the house. Any suggestions or help would be appreciated.

hey noticed noone knows how to reply to you post. From what i know a meth lab is really a major environmental hazard. Have a professional environmental clean up company estimate clean up costs and have them sign off on it and do the work . Then go about your rehab as usual. If you cant show that environmental specialist seal of approval you will have a hard time convincing a buyer to buy.
