"buying on Contract" counties

"buying on Contract" counties

Has anyone ever heard of the concept of "buying on contract" through the county? The concept is that when you buy a deed for the property thru the county, the county will actually help you finance the property. For instance, if the property is worth 100K and you bought the deed for 50K, the county will allow you to put only 5K (10% down ) and allow to pay yearly payments (one payment per year) until its all paid off. This sounds really good but I have not found any counties that offer such a deal. Does anyone know of any counties that offer this?
