Sigh. Just to clarify for those new to this game, there's no such thing as a reval tax. Their property value was underassessed, and the taxes went up dramatically once that was corrected in the reval. $27k at 1.6% means their property was assessed at a value of $1.7m, seems about right given what was said.

Odd are this property was Downtown and not in the Heights, where properties were overwhelmingly overassessed, and paying more than they should have, prior to the reval.
