“It’s outrageous,” said Anne Page, a landlord who owns several rental properties in the West End. One of her property assessments went up more than 11%. On another building, it climbed 14%. She said she owes roughly $1,500 more in taxes on the two properties than she paid last year.

“It wouldn’t be so painful if it was just once, but every year it has gone up excessively. We can’t charge rents to cover it.”

McKeithen, who answers to the council, runs the office that is responsible for assessing roughly 74,000 properties annually. A major factor in his calculus is home sale prices, which assessments typically lag behind. As demand in a neighborhood drives up sale prices, the assessors revise values to align them with what a property could fetch at market, he said. Owners can dispute their assessment in an effort to reduce their tax bill by filing a complaint with McKeithen’s office.

Residential property values increased citywide, but the highest rate of growth occurred in neighborhoods that historically have not been considered strong real estate markets.

“Our traditionally strong neighborhoods have done well for so long that individuals are now going into other neighborhoods that are more affordable,” McKeithen said.
