Titi jun,
Salam,nice to see u again here.as you red in this news,it is better to have home inspection by professional home inspector in order to make sure that home you are buying not have a major issue.it cost 400-500 dollar but save thousands.some houses has a major problem like foundation crack, main repair needed for window or roof or water leaking in basement.
if you have an inspection,he will make a list of single points of damage.
by that mentioned law,if seller doesn't inform the buyer regarding past used of the house for drug,buyer could sue the seller.
good luck
