Been following this thread and thought I'd add a few observations. But first of all we don't live in PT. We have visited for 30 years or so and have owned an apartment in Algarve for more than ten years. Based on our experience...
Many folk comment on the bureaucracy in Pt. We have fallen foul of it on more than one occcasion with utilities and banks. From our perspective it has nearly always been because we haven't read (or received) a communication. At first I tried to speak to officials in English - it just didn't wash and why should it? Now I am more confident with my portuguese (certainly not fluent) we get a much better reception and help! Our perspective is that there is a lot more paperwork in the banks than in the UK and it takes more time.
Costs - electricity and gas more expensive than the UK and no real market. Petrol cheaper in Spain.
Driving - it is different! But having driven in Ghana and Italy it is a breeze! You need to keep your eyes open but that helps wherever you are 🤣 🤣 🤣.
Dogs - to be honest can be intimidating (sorry, but I am not a dog lover) when you are out walking in the country. Usually they are chained or behind a fence. We have learnt to be confident and just keep walking.
We don't find CTT that reliable but probably haven't enough experience to comment.
We love so many aspects of time spent in Portugal. Overall the benefit to our lives, the culture and joy of visiting (frequently) far outway any negatives. We haven't relocated for family reasons. My constant advice is try to get to grips with the language - it is not easy but it is worth doing.
Hope this helps you.
