Meth Lab Property issues

[Zach Fagas]

Hey everyone,

I am looking at duplex this afternoon being sold by a guy who was living in the 1st floor unit and renting out the top unit (house hack).  In 2016 the door to the top unit was kicked in by the DEA busting a meth lab.  He had no idea what was going on in the top unit.  He has since had the entire remediation process done and has since put 40k into it over the last 2 years.  

My question: Is there any issues I am not aware of other than having to disclosure that there was a methlab discovered in 2016 whenever I sell I would sell it in the future?
