Tax Deed Auction Deposits

[Bernard DePascale]

Now that I feel more confident in bidding on my first property, I am unsure/concerned about prior/following costs. How do the deposits work (FL for example)? Each county seems a little different, but how do I calculate what I am depositing? Is there a preferred method most likely out of driving distance. 

Also, besides paying the deposit and bid amount, are there any hidden fees to take into consideration? Extra court costs, back taxes, etc.?

Thanks for any help. This site has been a blessing.
