I think it is not a bad idea Steven as long as you make sure you know the condition of the property, but that is with any property. Be sure to check the local laws of the tax delinquents for your county you are wholesaling in because there are different time periods when the owner has a right to purchase the property back. But I an not an expert on tax delinquent properties.
@Steven Steward I think it's a very good idea. Some of these require more research than others of the owner is deceased. But you can look up properties in the Houston tax website for delinquent properties. It takes a long time but probably the cheapest way.
