This happened to me in August. I was refinancing a house, and the appraisal came back way under what I'd underwritten. Not a little under. Tens of thousands under. I said absolutely not. I turned that lender down, opened a file with another lender, and the second appraisal came back right around my number. On a refinance, you can do that. You can switch lenders and get a new appraisal. When it's your end buyer's appraisal, you have fewer choices. You can fight it, you can lower your price, or you can let that buyer go and find another one, and that could cost you months of payments. And there are new appraisal rules out there, so this is happening more. That's why I build room into my numbers before I ever buy. Has an appraisal ever surprised you, good or bad? Tell me what happened.
