Miami-Dade Tax Deed Sales: Bidding, Payment, and Surviving Liens

Miami-Dade tax deed sales are public online auctions run by the Clerk of the Court and Comptroller, where properties with unpaid real estate taxes are sold to the highest bidder. The auctions happen on the county’s RealAuction portal, opening bids are set by statute, and the winner has 24 hours to pay in full. A tax deed transfers ownership, but it does not deliver a clean, insurable title, and some government liens survive the sale. Everything below is what you need to understand before placing a bid.

How a Property Gets to the Auction

The county does not sell a property the moment taxes go unpaid. The Tax Collector first holds a tax certificate sale, usually by June 1 each year, where investors buy the unpaid tax debt as a lien that earns interest. Nothing else happens unless the certificate holder pushes further.

After waiting at least two years from April 1 of the year the certificate was issued, the holder can file a tax deed application with the Tax Collector, paying a $75 application fee plus the cost of redeeming any other outstanding certificates on the same parcel.¹ The holder also covers advertising and notification costs. Once the file is complete, the Clerk sets an auction date.

One thing to know before you invest time researching a listing: the owner (or anyone) can redeem the certificate at any point before the tax deed is actually issued, paying the face amount plus interest, costs, and any omitted taxes, with a minimum 5 percent interest floor.² Properties do drop off the calendar at the last minute. Don’t build a plan around any single parcel.

Where To Find Listings and What To Check

Miami-Dade posts all upcoming tax deed sales on the RealAuction portal at miamidade.realforeclose.com.³ Each listing shows the tax deed number, the owner of record, a legal description, and the sale date. The tax deed number is what you use to pull the full application file through the Clerk’s public records search, where you will find the notices sent to interested parties and the verified list of liens.

Cross-check that file against the Miami-Dade Property Appraiser’s database for zoning, assessed value, physical characteristics, and homestead status. Homestead status changes the opening bid math dramatically, so confirm it before you calculate anything.

You Buy As-Is, Sight Unseen

There are no warranties on a tax deed property. No guarantees about title, condition, environmental issues, zoning, utilities, or whether a structure on the parcel is actually standing. You have no legal right to enter or inspect. A drive-by, aerial imagery, and public records are the extent of your due diligence. Experienced bidders assume the worst about condition and price the risk in.

How the Opening Bid Is Set

Every auction starts at a statutory minimum, and the formula depends on whether the property is homesteaded.

Non-homestead property: the total needed to redeem all tax certificates on the property, plus interest at 1.5 percent per month from the month after the application through the month of sale, plus the certificate holder’s costs to bring the property to auction.
Homestead property: everything above, plus an amount equal to one-half of the property’s most recent assessed value.

Any additional certificates or delinquent taxes that accrued after the original application also get rolled into the minimum.⁴ The homestead bump catches new bidders off guard. A property with $8,000 in back taxes but a $300,000 assessed value opens above $150,000.

If no one outbids the certificate holder, the property goes to the certificate holder at the opening bid. If the holder doesn’t pay within 30 days, the parcel moves to the county’s list of lands available for taxes.

Registering and Funding Your Bidder Account

You register on RealAuction before the sale date with valid ID and contact information.⁵ A winning bidder must post a nonrefundable deposit of 5 percent of the bid or $200, whichever is greater.⁴ The system won’t let you bid unless cleared funds in your registry account can cover that deposit.

You can fund by ACH transfer or wire. ACH takes several business days to clear; wires usually clear within 24 hours. If your funds aren’t cleared by auction day, the bidding buttons stay dark. The platform tracks your balance and blocks any bid that would exceed it.

How the Bidding Works

The auction runs on proxy bidding. You enter the highest amount you are willing to pay, and the software raises your bid in small increments only as needed to stay on top of competitors. You pay slightly above the next-highest bid, not your ceiling, unless someone matches you.

Each listing has a countdown clock. When a new bid comes in near the end, the timer resets for an overtime window and keeps resetting until bidding stops. That prevents last-second sniping. The dashboard shows your position across every property you are watching.

Paying After You Win

Once the timer expires and your bid is accepted, you have 24 hours (excluding weekends and legal holidays) to pay the balance in full.⁴ The balance is your final bid minus the deposit, plus documentary stamp taxes, recording fees, and a $60 electronic sale fee. Payment goes to the Clerk by wire transfer or cashier’s check.

Miss the window and you lose the entire deposit. The Clerk cancels your bids, readvertises the property, and pays those costs out of what you forfeited. The Clerk can also refuse to accept your bids at future auctions.⁴ The clock runs fast when you are coordinating a wire.

Documentary Stamp Tax in Miami-Dade

Miami-Dade has its own doc stamp structure. A single-family home is taxed at $0.60 per $100 of the sale price. Any other property type, including commercial parcels, vacant land, and multifamily buildings, pays the $0.60 base plus a $0.45 per $100 surtax, for $1.05 per $100.⁶ On a $200,000 winning bid for a commercial parcel, that is $2,100 in stamps alone, due inside the same 24-hour payment window.

Which Liens Survive the Sale

A tax deed wipes out most private liens on the property, but not everything. Liens held by a municipal or county government survive.⁷ That includes code enforcement liens, special assessments for infrastructure, and municipal utility charges. Condominium, homeowners, and property owners association assessments that accrue after the tax deed is issued also attach to the property.

Private mortgages, civil judgment liens, and most other non-governmental encumbrances are extinguished. Restrictive covenants that limit how the property can be used generally survive, provided they don’t create a debt against the parcel. Search for government liens before you bid. A property that looks cheap at auction can carry tens of thousands in surviving municipal obligations.

Why the Title Still Isn’t Marketable

A tax deed transfers ownership, but most title insurance companies will not insure a property based on a tax deed alone. The notification process before the sale, however thorough, cannot guarantee that every interested party received actual notice. That gap leaves a cloud on title. Until you clear it, the property is hard to sell and hard to borrow against.

The standard fix is a quiet title action in circuit court. Florida law specifically authorizes tax deed grantees to bring the suit against anyone who held an interest before the deed was issued, and the only defense that works is proof that the taxes were actually paid before the deed was issued.⁸ You don’t have to trace the chain of title any further back than the deed itself.

A straightforward quiet title case typically runs $1,500 to $5,000 or more, and higher if anyone contests it. Expect several months. Build both the cost and the timeline into your bid math, because there is no way around this step if you want to sell with clean title or place a mortgage on the property.

Surplus Funds When the Sale Exceeds the Minimum

If a property sells for more than the statutory opening bid, the excess is surplus. The Clerk uses it first to pay off government liens of record, including tax certificates not part of the original application. Whatever remains is held for the former owner and any other parties who had a recorded interest in the property before the sale.⁹

Those parties receive a mailed notice and have 120 days from the notice date to file a written claim with the Clerk. Anyone other than the former owner who misses that deadline forfeits the right to the surplus permanently. If no one claims the money, it is presumed to belong to the former title holder and gets processed as unclaimed property.⁹
