Owner Financing if renter wants to buy- Good deal for landlord?

[Ohm Apiwat]

All, 

If this question been asked before I apologize in advance. I have heard a couple of times that if renter asked to buy on a owner financing term it will be good for us. 

Is it a good deal for a landlord? What are the benefits of owner financing? What if they stop the payment? 

Thanks in advance.
