Thanks for posting this home.
Is it fair to assume your wife will stay in Florida and this will be your man-cave?
@RhondaHonda brings up one of numerous issues. Accessibility for 60+ year old man. Not a friendly home for that. I studied the home, a few things that tell me the home will require significant work for an "easy life". One easy to spot item is the back deck. That should tell you volumes of the money spent (or not spent) on this home.
The back deck should be a key item to be enjoyed drinking coffee, listening to the crickets, etc; in this home the back deck is a patch of fill. You will always have bugs, and be dragging dirt in the house using the back deck. It appears to be a 16 inch minimum drop from the back door to the back outdoor space- WOW. If they couldn't get that right- what else is not right. The railroad ties are not a step in this configuration. They are a slip and fall hazard, that is why I state it truly is a 16" drop (the railroad ties don't fool me).
I love porcelain floors in a warm climate. In a non warm climate- porcelain floors on concrete are not enjoyable, especially as we age- the cold will always be draining you. The ductwork for the fireplace has a bend in it- why? I suspect it works, but I would question why a bend.
No outside lights on the home (less one chandelier at the front entrance). Why not? Super easy to install in a structure of this nature. The heating system is all from above, this can work in Florida, but in the mountains of Tennessee? I suspect the owner of this home is cold most of the time in the home, and has huge heating bills- and I suspect an electric heat pump furnace...... maybe a thousand dollars a month to comfortably heat in the winter.
No attached garage.... I see the outbuildings, but barnominiums should typically have a attached garage. Another significant flag.
Nice home, beautiful lot, but for a 60 year old man with health issues? Give me Jupiter, Florida all day long....
