Changing cost by value appraisal value after close
Hello bp community,
I recently had a property appraised by a lender and the property appraised slightly under purchase price. I disagreed with the appraisal due to the particular comps that were picked and offered different comps to the lender. The lender considered but ultimately decided that the appraisal value would stand. We wanted the property anyway so I brought extra cash to close. After close, I received notice that the appraisal was revised with the "cost by value approach" section adjusted significantly with depreciation decreased such that the overall value of the home increased significantly above the original appraisal price. Despite this change, the final appraisal value remained the same. Why was there a need to addend the appraisal to modify the cost by value approach and do I have any recourse at this point to argue against the original appraisal value? It's likely water under the bridge, but I've never seen an appraisal changed after close. Thank you!
