Whats the worst-case scenario when buying a seller-finance unit?

[Tyler J.]

I have been incredibly interested in buying a seller financed property, mostly now looking at the interest rates.
Im also incredibly worried, as this is my first time not doing an FHA loan. What is the worst that could happen? How can I protect myself? Im worried if something goes wrong Ill have to sell all my assets and be in eternal debt, but I think I may just not be too educated with the entire process.

Thanks all
