More Refinance Questions - Square Footage

[Carlyle Small]

So with my latest refinance the appraiser has my property at 300 square foot less than the county shows. My problem is that he is using comps based on the county measurements, and I fully believe this mismeasurement on the county side would apply to the comps as well since this is a planned community with cookie cutter layouts. Short of asking them to verify the square footage for the comps, which they likely wont do, is there any other course of action I can take?
