The buyer pays for the appraisal. This is one reason why if there is enough time between the inspection and mortgage commitment deadlines the buyer will wait to order the appraisal until after they've had the inspections done. This way if there is a major problem with inspections that would cause the buyer to want to terminate the transaction (check with your Realtor/real estate attorney about what your rights are) they can save the cost of the appraisal. Good luck to you with your home purchase!
