Just got my tax appraisal in the mail, umm what??? Major increase

So we bought a house in June for $210,000, appraised at $215k. Now I’m getting the appraisal for $246,000!?!? Wtf.

Also the appraiser counted less square feet so I need to bring that up. I know I can contest but gosh that’s a real pain. Ughhh. Anyone else get a surprise??
