Why didn't you have a Home Inspection,? Structural damages would have been sighted prior to your being liable for following through on the sale. You could have cancelled the sale, or withdrawn legally. The lender wouldn't have gotten as far as the appraisal. If he did, and the inspection missed it, well the inspector would have been liable. You could have saved the money you spent for the appraisal, if you purchased a home inspection. So hind sight is 20, 20. It's not the lender's fault you had the appraisal on the house you wanted to purchase. You don't see the bank waiving the appraisal [they wan't to know what they're paying for is worth it]. Why would you waive an inspection? You could have done an inspection for informational purposes only; which allows you to cancel, if you find unacceptable damages. By the way did you have a Agent?
