New bidders see a house assessed at $180,000 with an opening bid of $9,000 and think something is wrong. Nothing is wrong. The two numbers are not measuring the same thing.
The opening bid is the debt
On a tax deed the opening bid is the unpaid taxes, the interest on the certificates, the cost of the application, the clerk's fees, and the cost of the sale. That is all. It has nothing to do with what the house is worth. A $500,000 house with three years of unpaid taxes can open at $20,000.
One exception: if the property was the owner's homestead, Florida adds half the assessed value to the opening bid. That is why some parcels open much higher than their neighbors.
The assessed value is for taxes
The county property appraiser sets an assessed value once a year to compute the tax bill. In Florida it usually sits well under what the house would sell for. Homestead caps hold it down further. So the assessed value is a floor of sorts, not a market price. GovDeed's What's it Worth? tool lifts it by a set factor to get a rough market guess, and shows the ZIP typical value next to it.
The gap is a starting point, not a profit
If the opening bid is $9,000 and the assessed value is $180,000, the spread is 95 percent. The GovDeed score gives that a lot of points. It does not mean anyone will get the house for $9,000. Other bidders see the same number. In a busy county the price can climb to a large share of the value.
What the spread tells you is how much room there is. What it does not tell you: the condition of the house, who is living in it, whether a government lien survives, what title work will cost.

Foreclosures are different
On a foreclosure listing the big number is the final judgment, the amount the lender is owed. The lender usually bids that amount without paying cash. If the house is worth less than the judgment, the lender ends up with it. If it is worth more, outside bidders compete above the judgment.
