Selling a seller financed property. Question

[Kyle Dutson]

New here and after much research  I am deciding to expand my portfolio from just stocks to real estate aswell. That said, I will most likely be looking for a seller financed property. Assuming I find said property at the right price and deal, what happens if I want to sell before it is fully payed? Would this be part of the deal? An option to sell when and how I choose or a promiss to hold the property?

The reason for asking is mainly this. I want to buy/improve/hold/rent but trade up when the opportunity arises. If the seller is financing the property for a steady cashflow + interest, wouldn't I be putting them in a bad position if I sell 5yrs in? They make less money, lose their steady cash, and possibly get hit harder on taxes. 

Any insight and knowledge on the subject would be much appreciated.
