Seller financing parents house

[Christopher Uvanni]

Iv been self educating myself on my real estate investing as I'm graduations from school and getting a job and as I come home from being away for 7 months my parents house is for sale. I see a perfect opportunity for me to use seller financing. How should I go about this? Can anyone give me some advice on how to explain to them how I will repay them and how they can refinance to get their equity in the almost paid off house on market for 219k in a highly desired lake property 5 bedroom 2br. They want to down size but need the equity for the next house how can this work?
