dont normally agree with F/F but you cant live on 100e a week, 150e at a push, you need a car too, unless you want to spend your days on camposol, and some do , seen them do it, living day to day watching the pennies , a few beers at weekend trying their best not to get carried away and spend more than they should have, and its easy to fall into the drinking scene as you cant spend all day in the sun, and its normally single guys that have bought 60k houses, in walking distance to cats, but a normal retired cpl should be budgeting for at least the whole proceeds of there pension @ £160 ish each week, then any savings they make will tide them for any unforeseen circumstances that rarely gets mentioned, and early retirees should budget the same . so the person with 60k , should have at least 15 to 20k left,
obviously everyone is different, but when you first move over you will want to explore the area, eating out etc meeting ppl, few drinks as u do, that adds to the costs , but im sure the average pesron would get by on 1000e a month easily.
as for the 15k per cpl residency, F/F is correct, and that increases to 25k per person, after dec 2020 , but buying a property does help, but if your paying in 600 per month with the bank each month to avoid charges that would also help, also watch out for capital gains tax when selling this year in uk and applying for residency , as long as you invest the profit in a spanish property then you can avoid tax ,
the person with £60k reduce this to 43k ish or you will pay spanish tax onnit when resident ,or split it with spouse..ouch
