Owner financing for the 1st time.

[Ernes Sahic]

I am looking to owner finance my investment property I have out of state. The buyer and I have agreed on terms. 

Property is in Oklahoma 

I plan on contacting a local title company to see if they can help or know of a real estate attorney that can write up a contract? 

I would like some advice from others who have had experience with owner financing either buyer or seller. I would like to make sure both the Buyer and I are covered legally. 

What are some things I should make sure to add to the contract or must have in the contract?
