Seller Financing questions for a new investor!

[Hunter Lisk]

Hello I am very new to this and I am looking into becoming an investor, but I currently have very little money. I have heard about seller financing, and was wondering how often any of you have used or tried to use seller financing? Im looking mainly at getting 80% from a bank and getting the other 20% from the seller. Do most sellers agree to this? If they don't do you have any other methods to get a property with no money out of pocket? Thanks!
