I had similar, however that was 6 years ago or so when the market was just starting to heat up. The appraisal looked at previous sales, but there was such low inventory that there weren't many comps to compare to, and none of them recent. The seller wouldn't come down much, so in order to make up the difference I had to cut into my down payment (which means instead of 20% down it was only 11% down, as only the appraised value counted toward my LTV and I got stuck with PMI for a few years).
