Owner financing is not like having a rental property. You still have to collect the payment each month, but you are now the LENDER instead of the LANDLORD. You are not responsible for repairs or any of that fun stuff. You just collect the payment (with interest). If they default on the note, then you foreclose on them (as opposed to eviction).
Owner financing can be quite lucritive and there are many investors who make a lot of money doing that. You sell the home for more than what it is worth, and charge a high interest rate and collect a big down payment.
Lets say market value for your home is 90k. Sell it for 100k, require a minimum of 10k-20k in cash as down payment, then finance the balance over 20 years at 12% interest rate. Just make sure you do your own credit, background, and employment checks. Your real estate agent should be able to help you with everything except for drafting the loan documents. A real estate attorney would have to help you with that.
Best of luck!
