I’m doing a test version of what you are planning with a few different facts: in Mexico, no spouse, no kids. I did sell the house and most all of my possessions for peace of mind. Mexico is giving the chance to improve the Spanish before I decide if I’ll stay here or try other Latin America or European country.
That said: one item I saw with Spain is a net worth tax. I think it’s set regionally. Madrid is at zero but no information on the cities you listed. Might want to google that a bit and see if you might get pulled into it or not.
Not Spain specific, but have you thought about where to maintain a permanent mailing address? One of the addresses for the kids would work. Plus consider a service that scans your mail for other things. Plus consider as much electronic delivery as you deem acceptable.
Consider a VPN. Some banks (Marcus for example) won’t let me connect from a non-US IP address.
Rent at first don’t buy.
PS: I agree with you comment about Memphis. Lived in Cooper-Young for years. Was happy to leave.
I have researched tax issues and it's muddy at best. Appears that if you live in Spain for 186 days or more (don't have to be consecutively) in a calendar year you're considered at tax resident. Rather than guessing and making a big mistake I've scheduled a consult with a firm that specializes in expat taxation issues. Curious - how is the taxation handled in Mexico?
