In Florida foreclosure is judicial which means it goes through the court system and it is estimated to take 180 days. (check with your attorney if it happening to you.)
Non-judicial foreclosure is not available
There is a right of redemption can end at the foreclosure sale altough a court can specify another time limit. (again this can be complicated make sure you are properly educated and prepared.)
If the Lender recovers less than the value of the loan, Lenders are allowed to collect on the the deficiency.
