How does someone do Owner Financing on a house?

[Xanthia Alysha]

I am looking to sell my house and offer owner financing to open up for more potential buyers and an increased sales price. I need to know what paperwork I need to do to complete the transaction. Do I need to notify my current lender? Should I consult an "expert" or is this something I can do myself? I rather not pay someone if it is just a matter of doing the leg work.
