I am not an appraiser but am instead a potential homebuyer in AZ. I am trying to close on a newly built home through a builder. I had gone through 1 of their preferred lenders for the loan process but the appraisal came back 50K lower than the purchase price. As a response to this, we had decided to get another appraisal through the other preferred lender and much to our surprise it came in 20K higher than the purchase price. This puts the two appraisals at 70K gap. In looking at the appraisals, I noticed the first weighed their appraisal mainly on resale comps while the second one weighed mainly on new home sales. Not knowing much about appraisals (and hoping you might be able to shed some light), do appraisers have the liberty between choosing comps on new home sales or resales? Any thoughts on what options I might have?
