@Coastfields: You are obviously in an early euphoric phase of a PPL.
How many flight hours did you pass already?
London, Portugal, France, Italy - sounds like a pack of dreams, but, knowing the usual training, how well are you prepared for international flying? It is easy once you get used to the procedures, but frankly, almost noch school will teach you the necessary administration of these flights (Just to point one, do you know what it takes to be allowed to take your dogs on international flight ... and back to the UK? -> not an easy issue!).
Next important question: what are your planned yearly hours flown? Depending on that it may make sense to think ownership quite early.
