Next is State Domicile and Mail..
You have no need to call any State that has State Income Taxes home..Why Should You pay a state when You ain't there & will receive No Benefits from them??
I suggest that You join the Escapees outfit for their Mail forwarding services AND use their (Your choice of 3 states) Domicile address for Your "State of Residence of Record" [All 3 do not have a State Income Tax..TX, SD, FL.]
[Disclaimer.. We are Fulltimers and Use the Escapees for our Mail and State Domicile (South Dakota) With No state Income Tax and We try to spend as much time as We can in States that Do Not have Sales Taxes..ie: Win Win Win.
Just have a few "Personal observations and thoughts on Your finances and domicile.
1) Buy your "first rv" and work out it's bugs....then when the time is near to retire and travel
2) I Strongly suggest that "IF" You are planning on selling out and going "Full Time".
Do so Completely.. ie: Have one hell of a Garage sale, and sell/donate/give away or to the dump everything that ain't welded down, Then put the home on the market.. Don't be screwing around with any "Sounds Good" but are BS plans or Reverse mortgages..
2) Take the proceeds from everything and Invest the funds LONG TERM.. Reason is that There WILL Become the Time that You and Your Spouse Will have to "Hang up the Spurs" and again settle down to live out Your final days..and those "Invested Funds" are there to see you thru the end days..
