Over the recorded series, Lake Harriet Estates’s median sold price moved from $137,950 (2016) to $290,000 (12 months ending 2026-09-20) — +110% over that span, with every year’s figure from recorded closings, not a model.
The recorded series starts in 2016 at $137,950. Against the 2024 peak of $340,000, the current median stands at -15%. Annual sales volume here has ranged from 0 to 12 closings a year (10-yr average 3.9). With roughly 3.9 closings a year, Lake Harriet Estates’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 Lake Harriet Estates’s $290,000 median and Seminole County’s adopted 15.18 mills (FY2025-26), a home assessed at that price carries roughly $4,400 a year in property tax before exemptions, or about $3,800 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 Seminole County tax page.
Demand check: 100% of Lake Harriet Estates’s listings are under contract, against 15% for ZIP 32714 and 25% for Seminole County as a whole — the community is absorbing faster than its surroundings.
