The recorded series starts in 2013 at $174,000. Against the 2025 peak of $569,900, the current median stands at -43%. Annual sales volume here has ranged from 0 to 6 closings a year (10-yr average 2.9). With roughly 2.9 closings a year, HARBOUR SHORES, SI’s medians move in steps, not curves — a handful of unusual sales can swing a year, which is why the sales count sits next to every figure above.
At HARBOUR SHORES, SI’s $325,000 median and Monroe County’s adopted 8.816 mills (FY2025-26), a home assessed at that price carries roughly $2,870 a year in property tax before exemptions, or about $2,520 with the full Florida homestead exemption — a buyer’s first-year figure; a long-time owner’s Save Our Homes cap can be far lower, which is one reason resale taxes jump at closing. Municipal and special-district millage varies inside the county; see the Monroe County tax page.
