Seller bought tax certification

[Gurjeet Brar]

Hello everyone. I am asking for expert advise on a property that i am considering. Seller bought tax certification because homeowner was behind on taxes. He is selling at a very discounted price. According to him, all the pending or existing leins will disappear on the home once he foreclose on the homeowner where then i can buy from him. He said even the bank will not come after getting their money. What is the best way to structure the deal? I have no prior experience in this. Wondering if anyone out there sold or purchased home in such cases. Appreciate your feedback.
