How do I approach an owner for owner financing?

[Kyle Clevenger]

 I think I need to start with a small background so the question might make sense. I recently bought my second home and am able to turn my first one into a rental. The tenants I've found are actually friends and neighbors from a couple doors down the road. They were previously renting and they mentioned their landlord is a great guy but is getting old and I've noticed he hasn't exactly kept up with market rates in rent and hasn't paid too much attention to the house. With all of that being said I want to figure out a way to approach the owner with hopes of figuring out an owner finance option for his rental property. I want to do it this way because I am leaving the country for "work" and this doesn't pay as much as my normal occupation does.  Even though I'm leaving, I don't want that to slow me down in my real estate investing. I'm pretty new, but I have fallen in love with real estate. I don't want being away for a year to slow me down for that year. Which brings up some other potential questions, but I will refrain and maybe ask those in the future. Thanks a ton! The podcasts, forums, and the books have changed my life already and I can't wait to see where they help me get in the future!
