Your best bet is to let the buyer know you have changed your mind for personal reasons and want to pull out of the sale. If the buyers have not spent too much money, they are usually reasonable. If they have already paid for the appraisal and inspection, you should offer to reimburse for those costs. A smart buyer will know that buying a house from someone who does not want to sell carries a lot of risks. Even if they threaten to bring you to court, they are not likely to follow through. Too much hassle and no one wants to buy a house under a shadow of a court case. Also, awards in these cases seldom cover more than what the buyer has spent (e.g.. moving company deposit, appraisal costs, etc.). And those companies will usually provide a credit for future moves. Good luck.
