Still, at the same time, they refuse to buy my condo, putting me in a very tough situation where I had to foreclose on the apartment to find out later that they picked up the property at the foreclosure court for pennies.If you're concerned about repairs, don't be.

Never seen that court case. 

Have him say you’re sorry if you offended the seller and say you agree to waive all your contingencies and would like to proceed including putting your earnest deposit at risk.Otherwise call it a win you escaped the deal at no cost.
