Miami (33184): The Seller’s Tax Bill Is Not Your Tax Bill
The typical home here is carried on the tax roll 45.1% below its market value — a median gap of $183,470 — because Florida’s Save Our Homes cap held the current owner’s assessment down for years. That protection does not transfer. When you buy, the assessment resets toward what you paid.
What is actually happening
Florida’s Save Our Homes amendment caps how fast a homesteaded property’s assessed value can rise each year, no matter what the market does. Hold a home for a decade in a rising market and the assessed value falls far behind what the house is worth. That is why Miami (33184)’s median assessed value ($241,576) sits so far under its median market value ($425,046).
The cap belongs to the owner, not the house. On sale, the property is reassessed toward its market value — in practice, toward what you paid. So a buyer who budgets from the listing’s current tax bill is budgeting from a number that is about to disappear. Across this area that difference models out to roughly $2,011 a year at Miami-Dade’s typical non-school millage.
What to do about it
Before you offer: estimate taxes on your purchase price, not the seller’s assessment — our property tax after purchase calculator does exactly that, and the Save Our Homes estimator shows how your own cap accrues afterward. After you close: file for homestead exemption promptly so your cap starts accruing. Moving within Florida: ask about portability — you may be able to carry a large share of your accumulated benefit to the new home. And remember the other recurring lines: any CDD assessment rides on the same tax bill, and insurance is its own budget item entirely.
How old the housing stock is, and why it matters here
| Era | Share of parcels |
|---|---|
| Built before 1980 | 14% |
| 1980 to 1999 | 76% |
| 2000 to 2009 | 7% |
| 2010 or newer | 2% |
Median year built: 1984 (5,622 parcels with a construction year on the roll). With 2% of the stock built since 2010, this is newer construction by Florida standards, which usually means current wind-mitigation features and a friendlier insurance market. Newer also often means a community development district on the tax bill. See what that means for premiums on our Florida insurance page.

No estimate of any specific property’s taxes, and no promise about your bill. These are medians across thousands of parcels on the county’s certified roll, and the dollar figure is a modeled county-typical estimate at the county’s non-school millage — your actual bill depends on your purchase price, your taxing district, your exemptions, and any portability you bring with you. The one number that binds is on the tax bill after you close.
For each parcel on the Florida DOR certified tax roll we compare just/market value (mv) with assessed non-school value (av). Save Our Homes caps annual assessment growth for homesteaded owners, so a long-held home sits well below market on the roll; on sale the assessment resets toward the purchase price. The median gap per area therefore approximates the property-tax increase a new buyer inherits. Implied annual delta = median gap x the county's typical NON-SCHOOL millage (matched to the non-school assessed basis), a modeled county-typical figure, not a quote for any property. Parcels below $50,000 market value, with assessed above market, or with an assessed/market ratio under 0.15 (agricultural and exempt classifications) are excluded; the excluded count is reported per county. Areas are published only at 800+ qualifying parcels (ZIP) or 5,000+ (county). Aggregates only; no parcel-level or address-level figures are published. Roll year 2025; millage vintage FY2025-26.
