Searching for property data in Miami-Dade isn't just about typing an address into a bar and hitting enter. Honestly, if you've ever tried to navigate the official portals without a plan, you know it's a bit of a maze. You're looking for a "folio," but the site gives you a "millage rate" or a "TRIM notice" instead. It’s a lot.
Whether you're a first-time homebuyer trying to see if a seller is inflating their square footage or a seasoned investor tracking a portfolio in Hialeah, the Miami Dade County real property search is your primary weapon. But here's the thing: most people use about 10% of what the tool actually offers.
The Independent Era: Tomas Regalado and 2026 Updates
As of early 2026, the game has changed slightly. Following the 2024 election, Tomas Regalado took over as the Property Appraiser of what is now a newly independent, constitutional office. This shift matters because the office is putting a massive focus on transparency and fraud prevention.
If you haven't checked the portal lately, you'll notice a heavier emphasis on combatting homestead exemption fraud and deed theft. They’ve beefed up the "Targeted Personal Property" search and made the GIS mapping layers a lot smoother.
Decoding the 13-Digit Folio Secret
Basically, every piece of dirt in Miami-Dade has a 13-digit social security number. We call it a folio.
If you have the folio, you have everything. Most people search by address, but addresses change or get entered wrong (is it "Road" or "Rd"?). The folio number is absolute.
- The first two digits: These tell you the municipality. For example, "30" means you're in unincorporated Miami-Dade. "01" is the City of Miami. "02" is Miami Beach.
- The middle digits: These represent the township, range, and section—the old-school grid system surveyors use.
- The last four digits: That’s the specific parcel identifier.
If you’re looking at a condo, the folio is your best friend. Searching a condo address often brings up 400 results. If you have that 13-digit string, you go straight to the unit's specific data.
What You Should Actually Look At (Beyond the Price)
When you run a Miami Dade County real property search, don’t just look at the "Market Value." That number is often different from what a realtor tells you or what Zillow says.

The Property Appraiser's "Market Value" is for tax purposes. It’s calculated based on mass appraisal techniques. In a hot 2026 market where single-family homes are hovering around a median of $660,000, the "Assessed Value" might be much lower due to the "Save Our Homes" cap.
Watch out for the "Adjusted Square Footage."
This is a huge point of contention. The county uses "Adjusted Square Feet" to determine value, which counts areas like porches or garages differently than the "Living Area." If a seller claims 2,500 square feet but the county says 1,800 adjusted, you’ve got some leverage in your negotiations.
The TRIM Notice: Your Annual Reality Check
Every August, the office sends out the Truth in Millage (TRIM) notice. You can find this online through the property search tool.
It isn't a bill.
It’s a "heads up."
It shows you what your taxes will be based on the proposed millage rates from the School Board, the County, and your city. If you think your assessment is too high, the TRIM notice is your window to file a petition with the Value Adjustment Board (VAB).
Practical Hacks for the Power User
If you're using the search tool right now, try these:
- The "Walk-the-Street" Feature: Don’t know the house number? Just enter the street name and the "From" and "To" blocks. It’s great for scouting entire neighborhoods.
- Sales Comparison Tool: Instead of guessing what a house is worth, use the "Comparable Sales" tab within the search results. It pulls actual recorded deeds from the last year within a specific radius.
- Aerial Photography: The county keeps historical aerials. You can literally see how a property looked in 2018 versus 2025 to see if that "new" deck was actually permitted.
Avoiding the "New Owner" Tax Trap
Here is where people get burned. You buy a house from someone who has lived there for 30 years. Their taxes are $3,000 a year because of their exemptions.
You buy it, and suddenly your bill is $9,000.
Why? Because when ownership changes, the "Save Our Homes" cap resets. The property is reassessed at full market value for the new owner.
Always use the Property Tax Estimator on the appraiser's site before you close. It’ll save you from a massive financial heart attack in your first year of ownership.
Actionable Next Steps
- Locate your Folio Number: Use the address search on the Miami-Dade Property Appraiser site to find your 13-digit ID.
- Check your Exemptions: Ensure your Homestead Exemption is actually applied if the home is your primary residence.
- Run a "Sales Comp": Use the built-in tool to see what your neighbors actually paid, not just what they listed for on the MLS.
- Review the Building Sketch: Make sure the "Living Area" matches what you're actually living in; if it doesn't, you might be overpaying on taxes or have unpermitted additions.
