Depending on the state foreclosure laws the cost and time to get back the property can be significant.
Being an agent from California means nothing except they think they are smarter than you.
The credit probably has nice little problems that tell a story.
Why not sell outright so you can emotionally move on with your life.Even if you sell for five or ten thousand less it is worth the peace of mind.
2% down isn't squat.Between foreclosure costs,default payments on the owner finance and damage to the property you will lose money on this deal.
Why not give a lease option and have the money down non-refundable for any reason but credited off the sales price at closing??
You can do a lease purchase but then that creates a secured interest in the property and complicated things.
good luck
