I am going to be in the Bahamas for 45 days in late spring and hoping to avoid a turn around flight to Ft Lauderdale if I need to close anythingyou can go to the US embassy if they have one and get a notary.. thats how folks in many other countries close their deals its expensive and time consuming but probably less than air fair etc. 

@Philip Mullinax I use cool care heating and air for all 6 of my rentals and have never had anything but great experiences with them

And Amazon Air is in the process of moving their Florida Air Hub from the Tampa airport to the Lakeland Airport. 

If you install more 500 CFM you do need air in duct but check range hood manufacturer instructions.

And just FYI - last summer when much of the hospitality industry was gasping for air, I was running at 87-92% occupancy at my new guesthouse, with one guest comparing my hospitality to "kintsuji", the Japanese art form of mending broken pottery with gold.  

@Evelina KhaimovaI would suggest you ask the seller and or the HOA if they allow air bnb.

Any other type of real estate will qualify as long as it is held for rental, investment or business use, including assets like air rights, water rights, certain oil and gas interests, mineral rights, etc.  

Call me crazy, but have you considered doing air bnb in Connecticut? 

I'm an Air Force Brat but settled in South FL in 2005.

At -5° if will still put out the heat that it is supposed to, but efficiency will fall.You may need supplemental dehumidification and if you have a tight enclosure you might need supplemental ventilation.Anything you can do to tighten and insulate the building will help ensure that this project is successful.The proper way to size a mini split is to use a Manual J calculation and to use results from a blower door test as an input for air infiltration.
