I'm unaware of actual case law on this point, and so base my view entirely on BATFE's published regulations and rulings. 27 CFR 478.11 provides the following definition:
There's also a published ATF Ruling (ATF Rul. 80-21) that explicitly interprets this definition of State of Residency to out-of-state college students holding that
Owning a second home in another state, this is an area where I welcome any and all additional illumination.

Note to be picky, but the quoted "definition" from 27 CFR sec. 478.11 is entirely circular:
"During the time that A actually resides in State X, A is a resident of State X, and during the time that A actually resides in State Y, A is a resident of State Y."
Contextually, BATFE appears to believe that, if a person owns homes in two states, he is a resident of whichever state he is
present in, from time to time.
Frankly, GCA could define "residence" for purposes of a non-resident purchase prohibition any what they choose. My primary point is only that whatever
Florida might permit does not cover you vis-a-vis the feds; my secondary point is that BATFE's definition of "residence" is flatly at odds with that of the common law.
(Ponder this: I own a boat. The Internal Revenue Service classifies this boat as a "second home," on account of the presence of certain amenities. Does this mean I could stop in a gun store in every state along the ICW and, taking advantage of 27 C.F.R. sec. 478.11, make a "resident" purchase of a handgun?)
