Condominium foreclosure by hoa in Florida?

It's unclear from your question who owns the property, who is foreclosing on the unit and the reason for the foreclosure.

If you own the property, and you owe money -- either to a lender, to a tax authority or to the association for over-due assessments -- foreclosure should not be a surprise.

Foreclosure is usually accomplished either by a lender, a tax authority including the IRS, a co-owner, or the association.

Before action for foreclosure begins, the owner has been notified, warned, advised and otherwise informed of options in lieu of foreclosure, but that foreclosure is a possibility.

If not before now, the foreclosure action has your attention. You can attempt to work out a different result with whomever has taken the foreclosure action, which may prevent you losing your residence.
