I've done a lot of research on seller financing as that is the #1 strategy I am looking to incorporate in my investing career. Seller financing is all about the seller, not about the property! You need to understand their goals are ultimately create a win-win situation for everyone. You need to ask yourself, "How do I buy it? How do I never lose it?" Buying a property comes down to deal, debt, and equity (the deal always comes first). Never losing a property comes down to long term, fixed-rate debt with positive cashflow. The purchase price is the least important term when it comes to seller financing. Do you have the 20% down payment? If you do, great! If not, see if you can negotiate and bring down the down payment. The term length is perfect as it long term debt. As far as interest rate, I personally think that is very high since you can get a lower rate with banks, but does the property cashflow? And is it a cashflowing number you like and that you can grow from? Then, go for it! Ultimately, it's all about creating a win-win situation as I mentioned earlier and if the terms they gave you does not allow you to win, then you should show them why and negotiate.
