The entire place is basically toxic and can never be used again and it's now basically impossible for him to resell2.

We waited until the next morning when it was cool and they were less irritable, then covered the shed with a large tarp and set of a case of bug bombs.

The private investor makes significant returns without any work, we profit by controlling the entire process and creating solutions, the bank rids itself of a toxic asset, we help families keep their homes, and we employ local people in the communities where the properties reside.

Don't worry about irritating the seller with questions about the income, expenses, property condition or tenants.

Left the fridge full of toxic mold.

If you found out the properties were built on top of a toxic dump, would you use that information in your negotiations?
