Funny, I just logged in to see if there were any more replies.
Current status: I pressured the lender to get the AMC to use a local appraiser and pay a 'real' and legitimate amount to appraise. They agreed, however the lender changed the terms based on the first appraiser's HBU analysis, requiring an even larger downpayment. So....I changed lenders to a local lender that uses local appraisers. Appraisal fee will be higher, of course. But we're still getting that together. Our contract was extended, naturally. I'll report back as to what happens.
