Specifically, I'm curious about the cost and process involved.I'm considering upgrading to a 400-amp service, which I believe could be divided into two 125-amp panels, one 100-amp panel, and one 50-amp panel or some other combination.

Added solar panels and a hot tub.

They want new electric panel, this home has Zinsco and that is one of the thing that we are not eligible to be insured.

Quote from @Nick Grassi:Not sure about Florida, but my experience with solar.. 5 years or more ago, buyers would take over leased panels and not have any issues with getting a solar lease from the owner prior to them.

You might have a home that literally takes one dividing wall of 2x4s and a kitchenette, or you might have a home that you need to add exterior doors, breaker panels, relocating utilities, etc.

Just know what you're buying as there's still a lot of FP panels, 60 amp service, aluminum wiring, asbestos tiles/tape, and plaster & lathe walls.  

I had ring cameras, but I found the best ones are actually solar outdoor cameras from Amazon.
