"There hasn't been a consistent reassessment process in theFulton County tax assessor's office," Rob Metcalf, managingdirector of JLL's Atlanta office, tells GlobeSt.com. "Someproperties haven't been revalued in the last ten years or so.There's a huge discrepancy in the last valuation thatoccurred."

Many of the estimated property tax increases appear somewhatnormal for the city's landmark buildings such as Bank of AmericaPlaza in Downtown Atlanta, which faces 18% higher taxes of $6.7million this year compared to what it paid for 2007, according toJLL figures. Other trophy assets with big tax bills includeMidtown's One Atlantic Center at $4.2 million, up 30%, andDowntown's 191 Peachtree at $2.5 million, up 73%.

Other properties face percentage increases in triple digits, andquadruple in one rare case. The Pinnacle office tower in Buckhead,which changed hands in recent years, faces a 208% higher tax billof $3.7 million this year, and Two Peachtree Pointe in Midtown sawits property taxes go up 316% to $1.5 million.
