You may have a problem -- you don't own the Florida property, and I assume you don't pay rent. I would suggest that the next time you are in Florida you have a consultation with a Florida attorney who is knowledgeable in the area of firearms law.
Your posts are not clear as to where your primary residence is today. If your work in DC is only a few part-time consulting gigs, do you mostly live in FL and go to DC only when you have an assignment, or are you still mostly in DC? If you live primarily in FL, why haven't you changed your driver's license and voter registration to FL? That would eliminate the problem.
