Contract for deed / how to structure a contract for deed deal

[Aaron Harren]

I am looking into a contract for deed deal on a 2 bedroom 1 bath home.  Seller has asked what I had in mind for a down payment and monthly payment option to move foreword with buying from her.  The price of the house is $32,000. I plan on using the house as a rental property.  Current rent rates for the area are $600. Looking for advice on struction this contract for deed deal?  Down payment, monthly payment and so on.  Thank you
