The strongest appeals are built before the hearing.
Commercial property tax evidence should explain why the assessment is too high, not simply that the bill is painful.
Comparable sales
Recent arms-length sales can show market value, especially when adjusted for location, age, size, use, condition, and date of sale.
Income and expenses
Rent rolls, vacancy, concessions, operating expenses, and capitalization rates can matter for income-producing property.
Condition and repairs
Photos, inspection notes, contractor estimates, environmental issues, and deferred maintenance can show value loss.
Incorrect property data
Building size, classification, land area, year built, use, occupancy, and improvements should match reality.
Unequal assessment
Similar properties may be assessed differently. A professional can identify whether unequal treatment supports an appeal.
Professional reports
Appraisals, broker opinions, engineering reports, and tax projections may help when the property is complex or high value.
