Appreciation YTD · $/SF CLOSED SALES
Appreciation YTD compares the median price per square foot of closed sales so far this year against the same period last year. Price per square foot rather than median price, because a median price moves with which homes sold — over this span South Beach ran +1.9% on median price but −4.3% per square foot. Effective tax rate: modeling in progress — the county roll carries no millage field, so we show “—” rather than an estimate.
