For the sake of time, I was omitting a lot of the details from point of tax certificate and point of ownership for FL tax liens.
More detail:
In short you will obtain your certificate and hold that certificate for 22 months from the date of origination. If you have obtained the certificate from the county struck off list then you will need to hold for the duration of time until matured. (Yes it is possible to apply for the tax deed immediately after obtaining a tax certificate that has been struck off to the county.) Once the 22 months have lapsed you will then apply to the county for a tax deed. Once your application has been received by the Tax Collector their office will: determine the amount of all other outstanding certificates and accrued interest on those certificates through the end of the month, determine the statutory cost of auction (about $75 currently), and determine the other small costs associated with the account. They will then notify you, you will make payment, then the process begins.
The Tax Collector will then:
Pay those other outstanding certificate holders their face value and accrued interest; and, order from the approved title company an Owners and Encumbrance Report; and, surrender to the Registry of the Clerk of Circuit Courts or Comptroller those statutory costs associated with the auction; and, order from the approved vendor an advertisement to run for four consecutive weeks in a newspaper of general circulation in the county; and, remit for recording to the County Clerk's office the statement of service and party accuracy, once the title report has been examined; and, send out letters of public notification to all parties named on the O&E report; and, examine documentation found in the Property Appraisers records to verify legal descriptions, plat maps, etc etc.
Then if unredeemed, the file is sent to the Clerk of Circuit Courts for review. If all is meeting statutory requirements then the file is stored or transferred to the Tax Deeds Office or transferred to the Comptrollers Office. (It depends on the county who handles it i.e. Palm Beach County it's the Comptroller, Marion County it's the Tax Deeds Office, Citrus County it is the Clerk's Office).
Then if redeemed, you will receive all of the funds invested in the venture and your accrued interest.
If the property moves from this point to the point of auction then the appropriate office will put on their schedule the tax deed sale. The opening bid for non homestead properties will be those costs you have rendered unto the Tax Collector and the interest accrued, if you do not receive the tax deed you then will be reimbursed. For homestead exempt properties the winning bidder or tax deed applicant will be required to render 50% of the appraised value of the property. This amount is added to the tax deed sale opening bid.
If there are no bidders at the tax deed sale the party applicant shall pay the required document stamps and if homestead exempt the additional amount added to have the tax deed issued to them; or, if the applicant fails to render payment for any reason the tax deed after 90 days may be entered into the "List of Lands Available for Taxes". All properties residing on the LOL by statute will remain there for 3 years unless purchased. Once a tax deed has remained for three years on the LOL the Board of County Commissioners will approve the escheatment of the property to the county.
As an applicant for tax deed you also, just as any other citizen, can bid at the tax deed sale.
So, you now either have your investment and interest or you have your tax deed. And this is the short version.
