Relocating from UK

I recently returned from 15 years residing in Australia, I never intended remaing in the UK my preferred locality was southern Spain, however , the British Government has removed us from the EU and has now made it very difficult to relocate anyone who can advise on a course of action for my wife and I would be much appreciated we are both UK citizens retired and both receiving adequate funds from our pensions it was our intention to purchase a 2Bed 2Bath apartment on a high quality urbanisation Close to or on a golf complex.

Any advise info etc would be very welcome
