Since you kind of asked.....
I have lived in Massachusetts. I have lived in Florida.
NH is even colder. You have too much cold weather thinking. In NH you need a house that you can button up against the winter chill and snows. In your Okeechobee situation, I would buy and move a high class single or double wide mobile home onto your spacious acreage. Then extend outward with two screened in porches on concrete slabs. A large one for more family living space. A smaller one for your workshop and tools and tinkering around.
You are moving to a rural situation. No need for a nice house. For A/C I would mount two powerful windows type air-conditioners for the rooms you use the most in the mobile home. I would also find a way to vent the hot air that your refrigerator throws off, into the outdoors. Or just place it on your family porch. Along w the stove (lol) during the hot months.
Most homes in FL have no basement. They are built on top of concrete slabs. Think slabs slabs slabs. For all of the above, my guess is $100,000- $120,000 -— For Okeechobee septic I think you can dig a leach field. No tank needed.
I would do a double-wide if the HOA allowed it ... yes even in the middle of nowhere in Okeechobee we have a HOA ($250/yr) ... though no one apparently pays attention to it, but the rules say a regular “Florida” style home of 1600+ sqft or greater.
I do want to put a 40’x60’ steel building on the property to house the cars, tractor, workshop, etc...
I have to build a 1 acre pond on the lot as well as per Florida EPA and county rules. All that site prep work is big $$$ now.
I have no mortgage so what I would sell the house (NH) for all goes to the new home. I already own the land free and clear in Okeechobee. The builder we want to do the job quoted over $405,000 just for the house!!! the steel building was another $150,000 a year ago. And that was when building materials were going up 10% per month! I can only imagine what the cost is now.
Gotta play the lottery more and hope to win.

Do you also play Russian Roulette?
