Why this is the lever

Fla. Stat. s.193.011(8)

Under s.193.011(8), Just Value must be net of the usual and reasonable costs of sale (customarily ~15%). Where an assessment meets or exceeds the gross price comparable properties actually sold for, it cannot reflect net-of-cost just value, and the Value Adjustment Board can reduce it.
