We have contemplated doing a lot of traveling and what to do with our house

Do we keep it to have an anchor? If we decided to live in Italy for 3 months, Seattle for 3 months, etc, we will need some way to make sure we can transport medical records. All plans are subject to change due to life, but we are saving 45% of our income so that we can at least try some of these alternatives. Maybe house swapping if it is still in.
