Fla. Stat. § 702.04
When a mortgage includes lands, railroad track, right-of-way, or terminal facilities and station grounds, lying in two or more counties, it may be foreclosed in any one of said counties, and all proceedings shall be had in that county as if all the mortgaged land, railroad track, right-of-way, or terminal facilities and station grounds lay therein, except that notice of the sale must be published in every county wherein any of the lands, railroad track, right-of-way, or terminal facilities and station grounds to be sold lie. After final disposition of the suit, the clerk of the circuit court shall prepare and forward a certified copy of the decree of foreclosure and sale and of the decree of confirmation of sale to the clerk of the circuit court of every county wherein any of the mortgaged lands, railroad tracks, right-of-way, or terminal facilities and station grounds lie, to be recorded in the foreign judgment book of each such county, and the costs of such copies and of the record thereof shall be taxed as costs in the cause.
