We sold our apartment last year (sale agreed August 2020, completed November 2020) and purchased another one (sale agreed October 2020, completed January 2021). We were in Spain for the sale as I sold it myself, I got POA fro my solicitor, packed up our apartment and put it all into storage.
Im so glad we did as we werent allowed back into Spain to complete in person. That was in January, and as we all know, things change weekly. We were not allowed, under any circumstance, to enter Spain just to view properties.
This was my experience, it wasnt easy and you need to have nerves of steel. My advice, for what its worth. Leave it well alone until you can legally enter Spain.
Best of luck.
