So, you have a deal for 250K. If the appraisal came in low the buyer can cover the difference (not likely since it’s about 15% of the original price), or cut a new deal, or simply cancel the deal (assuming the proper contingencies were in place).
Does the $215K make sense to you based on the current market in your area ? Or is the buyer using a buddy appraisal to try to get a better deal on the property ?
… just a thought.
If the 215K is reasonable, then I would consider making an offer to split the difference at 225 or so, depending on the buyers’ ability to make a down payment.
