Unsoundness is the deal breaker.
Poor conformation.
I bought horses that needed rescue and improved their groceries and retrained them to be reliable horses and resold them for a number of years. Always sold to good, reliable, homes. I quickly found out two things.
1. You cannot make a silk purse from a sow's ear.
2. A good horse took as much effort as a bad horse (conformation and soundness) so you might as well work good horses.
So that is what I did.
