Understand Treasure Island before you commit to an address
Treasure Island is sixty-five hundred people on the barrier island north of St. Pete Beach, with the widest beach in Pinellas County and a deliberately low-rise skyline. The city has resisted the height its neighbours allowed, which is much of its character. Figures are the same two indexes measured the same way in all 24 municipalities here, on Florida's rules including the homestead exemption. It is on a barrier island, which after the 2024 storm season is the most consequential fact about any address in this bay.
The cost of living in Treasure Island, and what a home costs
Two calculators on Florida's own rules: monthly compounding and the month private mortgage insurance stops, and the closing costs this state actually charges.
Rent or buy in Treasure Island
Whether buying here beats renting, and the year it turns over. With twenty-three of twenty-four municipalities down last year, appreciation is the input worth arguing with.
Mortgage calculator
Monthly compounding, the 30-year fixed loan, the private mortgage insurance a low down payment triggers, and Florida's documentary stamp and intangible taxes on the loan itself.
Then work out whether Treasure Island is the right part of the bay
No neighborhood guides for Treasure Island yet. What is here instead is both sides of the bay on one comparable footing.

The other municipality here with a hub of its own: the same row of figures as this table, the five areas the city divides into, and neighborhood guides on the peninsula where Helene's surge was the largest on record.

The same rules, the same exemptions and the same two Zillow indexes, and against every expectation, higher insurance premiums than Tampa Bay on a coast that has taken less surge.
Compare the two coastsWhat buying in Treasure Island actually involves
The total of 16.5501 mills gives an effective rate of 1.53% and a bill of about $8,000 on a typical home value of $523,869, down 6.0% year over year. Like every barrier-island municipality here the rate is low and the bill is not, because the base is what it is.
Everything on this island runs through 2024. Helene's surge crossed it, the older single-story houses on the canals took water, and the rebuilding since has run into the substantial improvement rule. A repair costing more than half the structure's value forces the whole thing to be elevated to current code, which on a 1950s slab house is often more than the house is worth. That calculation is being made on hundreds of lots here right now and it is what the next few years of this market will be about.
Most of the residential stock is on finger canals, which makes the seawall the single largest capital item attached to a house here. Seawalls on this island date largely from the 1950s and 1960s, replacement runs into six figures, and the condition of the neighbours' walls affects yours. It is an inspection line rather than a formality.
The city has held its low-rise character, which means the housing is mostly one and two stories at low elevation. That is the combination the 2024 surge found, and it is also why the rebuilding question here is sharper than on islands with newer, taller stock: an elevated replacement house looks nothing like what stood on the lot before, and whole streets are working through that.
Moving to Treasure Island: check these before you commit
- Substantial damage and substantial improvement determinations on the property, which govern what can be repaired and what must be elevated.
- Canal seawall condition, which on this island is widespread and expensive.
- Flood insurance quoted separately, and the elevation certificate.
- Seawall age and condition, and whether any permits for its repair are outstanding.
- What an elevated rebuild on the lot would actually cost and look like, if the house is older and low.
Treasure Island's own council sets 3.8129 of the 16.5501 mills charged here. The rest is Pinellas County, the school board and the countywide special districts, and the 16.5501 is the total Pinellas County publishes for this taxing district rather than a figure assembled on this site.
Sourced, dated, and separated from the guesswork
Every Treasure Island figure below is cited, stamped with the period it describes, and editable, because a number for the whole city rarely describes your purchase. Appreciation and investment returns are assumptions rather than facts, and they are labelled that way. Read the methodology for how the line is drawn.
