Rent-to-own VS Deed of trust?

[Jocilyn Oler]

I have owned a mobile home for the last year.  It has provided awesome cash flow.  The park is changing the rules and I can no longer sublease.  So  I need to sell the home. 

I've found several interested parties who all need financing.  I am willing to provide the financing.  What are your opinions on doing a rent-to-own route versus selling the home using a deed of trust? 

We are leaning toward the deed of trust route right now.  We are selling the home for $35K.  Your thoughts on how much  the down payment needs to be?  Is requiring 7% interest way too low? Should I be expecting a higher interest rate? 

Two of the parties are fine taking seven years to fully pay off the home.  

Your thoughts and advice on this type of deal is appreciated!
