First flip, meth contaminated

[Noah Applegate]

Help, I purchased a townhome from a wholesaler.  I found out after the purchase that it was a frequented drug house.  Tenants told me seller had tried to sell to investors before but after meth test came back positive they were going to drop the price significantly.  I have not had the chance to test it for meth myself, but All things are pointing to math contamination.  This was not disclosed to me before the purchase and now I'm finding myself in a situation that could end in serious financial harm to myself.  Do I have any reports with the wholesaler or owner of the house?  Can I "u buy" the house?  

This is my first flip and I'm using a heloc on my own primary to fund the project.
