8051 N Tamiami Trail in Sarasota is a corporate office. A lot of businesses and registered agents use Suite E6 as their mailing address. 411 Walnut St in Green Cove Springs (near Jacksonville) appears to be a dingy office housing a process server. I believe that since Null himself is listed as registered agent, it is likely he lives within driving distance of the latter office, so it is abundantly clear he lives somewhere in the greater Jacksonville area.
