I can think of lots of reasons to buy a lot.
From Indiana to Georgia? No brainer.
To be near family? No brainer.
Love the beach/lakes and/or fishing? No brainer.
Ready to retire on lower income? No brainer.
With everybody on the planet buying RVs during the latest craze it is getting harder and harder to get spots when and where you want them.
I'd buy a lot in FL if only to establish domicile and avoid the BS state park roulette and the 3 month minimum rentals in private RV parks during the winter.
I found a nice one in Bluewater RV Resort in the keys for sale. Just at a million USDs :E
