Research guide

How the sale works in each county we cover

Tax sales let a county recover unpaid property taxes by selling the property or an interest in it. Who runs the sale, how bidding works and what the buyer receives differ from county to county. Start from the office that runs your sale.

Miami-Dade County, Florida

Run by the Miami-Dade Clerk of the Court

What is sold
Tax deed sales, held online. The county site also tracks mortgage foreclosure sales, which are a separate proceeding with separate dates and results.
When
Sales run through the year rather than in one annual event.
Worth knowing
The Clerk sells without warranties about condition, title, use or obligations that may survive the sale.

Tax-defaulted property auctions. For 2026 the Treasurer lists its sales on GovEase, with separate main and follow-up sales.

Before you bid: an eight-point checklist

Most expensive mistakes at tax sales come from what a listing does not say. Work through each point for every parcel.

  1. Confirm the sale type

    A tax certificate, a tax deed auction and a mortgage foreclosure are different proceedings with different rules. Never mix their dates or results.

  2. Match the parcel

    Check that the parcel number, legal description, address and map all describe the same land. Listings with a wrong or missing address are common.

  3. Recheck the listing

    Items are withdrawn or redeemed up to the sale. Confirm the parcel is still offered on the official site before you register, deposit or bid.

  4. Read the event's own terms

    Registration deadlines, deposits and final-payment deadlines change between events. Use this sale's instructions, not last year's.

  5. Research title

    An opening bid says nothing about clear title. Find out which liens, assessments or claims may survive, and whether a title insurer will insure after the sale.

  6. Check access and use

    Confirm legal access, zoning and whether utilities reach the parcel. Many low-priced lots are landlocked, unbuildable or restricted.

  7. Plan for occupancy

    A deed does not deliver possession. Occupied property may need a legal process and time before you can use or resell it.

  8. Budget the whole cost

    Add fees, transfer taxes, recording, insurance, back utilities, repairs, holding time and resale costs before deciding what to bid.

Common questions

Is a tax sale property a bargain?

Sometimes, often not. Opening bids reflect unpaid taxes and costs, not market value. Many parcels sell for a small fraction of value because they carry real problems: no access, title defects, environmental issues or buildings that cannot be used. Price alone tells you very little.

What does a winning bid actually get me?

Usually a deed issued by the county after full payment, not immediate possession or insurable title. Deed type, warranties and what survives the sale differ by state and county, so read the selling office's terms for that event.

Why are historical results useful?

They show how often similar parcels actually sold, what they sold for relative to opening bids, and how often items were withdrawn. Treat an unknown outcome as unknown: a closed listing with no price is not proof that it went unsold.

Why does each county have its own site?

Each county runs its sale differently: different offices, platforms, schedules and record formats. A dedicated site can show that county's real sources, dates and gaps instead of flattening everything into one generic list.

Is this legal or investment advice?

No. These sites organize public records and point to official sources. Confirm everything with the selling office and get qualified legal and title advice for a specific purchase.

How these research sites work

Research workflow, not lead lists

Each county site is organized around its own records rather than a scraped national list. The aim is to help you screen parcels, understand the local auction, and move from a public list to a disciplined research plan before spending time or money on deeper diligence.

Useful before you sign in

Every county site publishes its explanations, source links, disclaimers and methodology notes in the open, so you can see what the data means, where it comes from, and which parts still need official verification.

Sourced, calculated or still unknown

We keep public records, derived calculations and research notes apart, which makes it clear what is sourced, what is calculated, and what still has to be checked independently.

Pick your county and start researching.
