Mobile home Lots

[Michael Swanigan]

Need to get some of your wisdom on this situation I'm going through.  I am purchasing a lot that allows mobile homes.  I want to owner finance them in order to make them affordable to buyers for a quick sale.  What type of paper work/documentation do I need in order to make the deal legal?  Do I need to hire a lawyer?  Also if they are making payments do they get the deed when they give me the down payment or do I hold on to it until they pay it off?  And if I keep the deed will they be allowed to purchase a mobile home from a dealer if they do not have the deed in hand? 

Anybody ever tried this strategy before? If so, please respond.
