I’m a personal injury attorney from Utah. To determine whether your house is a former meth house, you will want to check with your state Department of Housing to see what type of requirements there are for sellers to disclose this.
In my opinion, selling a house without disclosing that it is a former meth house is extremely deceptive. It really amounts to fraud.
They hold back this critical information to make more money. I think there should be federal law mandating disclosure in all 50 states.
