I say go for it !
My sister and her husband rented out their house here 2 years ago and now rent in Spain. They have got their residency permits, drive a Spanish purchased car and take language lessons.
This is all paid for by the rent from their UK property, so they have the perfect safety net.
They did all their research before they left, rented furnished the first year to test the waters, changed property at the end of that year and then shipped out their possessions.
Its working for them !
Good luck to you .
No fun being old under Andy Burnham .
Struggling with estrangement from 2 adult children and dont know where to go from here.

You're not.
