Seller financing sample contract/Questions

[Harri Smith]

Hi all
I am a considering doing a seller financing and wanted to know if someone had a sample of contract they could share. I am told I do not really need an attorney.
A few questions I have are:
1. Can I keep the title ( deed) to the house until balloon payment is made?
2. I want x amount per month and do not want to have to deal with interest. Do I need to specify interest amount? If so what are the advantages to the seller? Buyer?
I would require the buyer to pay city and county taxes, utilities, insurance, etc ( just like any other mortgage).
Thanks in advance.
