> you can sue them to close the deal but the juice isn’t worth the squeeze That really depends on the offer you accepted (A), the current value of the house (B), the cost of litigation (C), and the price you put on your time and mental energy (D). If A > B + C + D, it makes sense to force the buyer to close. And in most cases, you're relying on the buyer to close in order to be able to close on the house you're moving to so you may have no choice.
