How do I find sellers financing
How do you mean? You have to go out and talk to a person that owns the property and ask if he'll do financing for you. These are usually private deals and can be set up any way you and the seller agree on.
You can use a title rep to help you find the names, addresses, and phone numbers to homes that you are looking for. Also, white pages or spokeo can help you get info to the owners of a home
