Aventura sits at the northeast corner of Miami-Dade County, bounded by the Intracoastal Waterway to the east and the Broward County line to the north. Sunny Isles Beach is directly across the water. Hallandale Beach is directly north, in Broward. The city was incorporated in 1995 and covers roughly three and a half square miles.
That county line matters more than it appears. A property on one side and a property four blocks away on the other fall under different property appraisers, different school districts, different hospital taxing districts, and different millage. Buyers searching by radius rather than municipality routinely compare properties with materially different carrying costs without realizing it.
What is actually here
Aventura is condo-dominant. High-rise inventory concentrates along Biscayne Boulevard and the Intracoastal, with mid-rise and low-rise buildings inland. Single-family and townhouse product exists but is a minority of the inventory and turns over less frequently.
Building age spans roughly the early 1970s through current new construction. That range is the most consequential fact about buying here, because two buildings a block apart can carry entirely different structural compliance obligations depending on completion date.
2025 adopted millage
| Total millage | 16.7488 |
| School portion | 6.6330 |
| Non-school portion | 10.1158 |
| Municipal levy | 1.7261 |
| School share of bill | 39.6% |
Aventura has the lowest total millage of any city in this guide at 16.7488. The city's own levy is 1.7261 mills, roughly a tenth of the bill. Most of what an Aventura owner pays goes to the county and the school district.
The school share is the highest in this guide at 39.6 percent. That matters for anyone following Amendment 3, which would raise the homestead exemption against non-school levies only. Aventura's combination of low total millage and high school share means the estimated reduction here is smaller than in higher-millage Broward cities.

What determines the cost of ownership here
Because the inventory skews condominium and the building stock spans five decades, two statutory requirements do more to determine what a unit costs to own than the list price does.
Fla. Stat. 553.899 requires a structural milestone inspection for buildings three stories or more at 30 years, and at 25 years if within three miles of the coastline. Aventura's Intracoastal position places a meaningful share of the inventory in the earlier band, though the coastline determination is building-specific and should be verified rather than assumed.
Fla. Stat. 718.112(2)(g) requires a Structural Integrity Reserve Study and funding for the components it identifies. The HOA fee shown in a listing is a point in time, not a forecast. Two units at identical prices in buildings of different vintages can diverge by hundreds of dollars a month within two years.
Financing is affected as well. Fannie Mae and Freddie Mac condominium project standards require a minimum share of assessments allocated to reserves and have eliminated the limited review path for many projects. A building can be structurally sound and still be difficult to finance conventionally, which narrows the buyer pool on resale.
What I would check in Aventura
- Milestone inspection status and the report itself rather than a summary
- Whether the Structural Integrity Reserve Study is complete and whether reserves are funded to it
- Any special assessment voted, pending, or under discussion
- The estoppel, ordered early, since the timeline compresses closing
- Whether the building is warrantable, before assuming conventional financing
- The exact millage code, since the county line is close enough that cross-border comparisons involve different tax structures
- Non-ad valorem assessments, which are not included in the millage figure
- Lease restrictions and minimum lease terms if the plan involves renting
Aventura questions
What is the property tax rate in Aventura?
The 2025 adopted total millage is 16.7488, per the Miami-Dade County Property Appraiser. That is the lowest total of any city in this guide. The city's own portion is 1.7261 mills; the remainder goes to the school district, the county, and special districts. Non-ad valorem assessments are billed separately.
Are Aventura condos hard to finance?
It depends on the building, not the city. Conventional financing requires the project to meet Fannie Mae or Freddie Mac condominium standards, including reserve allocation requirements. Buildings with incomplete structural reserve studies or known deferred maintenance can fall outside those standards. Confirm project eligibility with your lender before waiving a financing contingency.
What is the difference between buying in Aventura and Hallandale Beach?
They are adjacent but in different counties. Hallandale Beach is in Broward with a 2025 adopted millage of 20.6717, against Aventura's 16.7488 in Miami-Dade. Different property appraiser, different school district, different hospital taxing district. On the same purchase price the annual carrying cost differs materially.
