Balloon on Seller Finance Note

[Randon B.]

I am about to put a house up for sell and I would like to sell finance the note. I was told that if I was selling to an owner occupy then I could not add a balloon as part of the note. Though if I was selling to an investor I could. 

How do you differentiate between an owner occupy and an investor during the procuring process?? Is it as simple as just asking? But who's to say they wont rent it out after closing etc?
