Primary Argument

The strongest basis for reduction is unequal appraisal under Tax Code Section 41.41(a)(2).

The subject property—a 113-year-old, 4-unit apartment building in documented fair condition with window air conditioning—is appraised at $154.26/sqft. Meanwhile:

  • 4632 Junius St Same year, lot size, block $119.31/sqft
  • 4609 Junius St 24 yrs newer, same config $140.33/sqft
  • 4637 Worth St 39 years newer $149.68/sqft

The subject is appraised 29.3% higher than an identically-aged neighbor and 9.9% higher than a significantly newer property with the same configuration. This disparity constitutes unequal appraisal.
