Your property tax bill says 2,800 square feet. Your home is actually 2,300 square feet. That 500 square foot error is costing you real money every single year.
Square footage errors are the #1 most fixable property tax mistake - and they're shockingly common.
Here's the math counties don't want you to do:
500 sq ft error × $200/sq ft value = $100,000 overassessment $100,000 × 2.5% tax rate = $2,500 extra per year
That's not a rounding error. That's a vacation. Every. Single. Year.
Counties measure square footage through:
They rarely actually measure your home.
Red flag: Your assessment shows 2,800 sq ft but your listing showed 2,200 sq ft Reality: They're counting your 600 sq ft garage
Red flag: Total square footage doubled when you bought Reality: They're counting raw basement as living space
Red flag: Square footage doesn't match any documentation Reality: Outdoor spaces counted as indoor
Red flag: Two-story home with impossible measurements Reality: They counted attic space as full floor
Red flag: Permit pulled but project cancelled Reality: County added phantom square footage
Red flag: Massive square footage for modest home Reality: Using data from demolished structure

Your tax bill implies:
Include county's own rules about measuring square footage. Show how they violated their own guidelines.
County: "Our aerial measurement shows..." You: "Aerial can't distinguish finished from unfinished space"
County: "The permit says..." You: "Permits don't equal completed work. Here's proof."
County: "We've always used this number..." You: "Length of error doesn't make it correct. Here's actual measurement."
County: "Close enough for assessment purposes..." You: "500 sq ft × $200 = $100,000 error is not 'close enough'"
