Property taxes in most of the US are against the property, not the owner. If you buy property and taxes weren't paid, you now owe the taxes...
And it's worth asking how much it cost in repairs to get that house to the point where it was legal to rent.
And if the house is in Detroit the last laugh may be by the seller...
