Seller Financing - Story, Sales Contract Resource and Numbers

[Kevin Blanchard]

I came across this property a number of years ago when the seller was trying to sell it for $600,000. It was a new construction project consisting of over 3,700 sq. ft. The interesting thing is that they timed the market wrong and didn't lower the price enough to catch up. Long-story short the seller ended up getting sick and was unable to complete the house. He has basically done everything on the exterior but the interior is only framed and rough electric. They have agreed to seller financing at $150,000. We are still working on the remaining terms but I was thinking I could sweeten the pot by saying I would pay them the balance within x amount of years (Perhaps 10 or so??) by refinancing the property. I am estimating that the property construction will cost about $125,000-$150,000, meaning I will be all in at $300,000 and the ARV will be $400,000.

Believe it or not I am considering this for my own personal residence and not an investment property. However my question is, does anyone have any resources for a Seller Financed Sales contract that they would be willing to share? I haven't reached out to my real estate lawyer yet so I am uncertain if he is familiar with seller financing but I wanted to be able to provide him with at least some type of framework to work off of.
