At the risk of offending expats I also believe everything we do has consequences and comes at a cost
If I choose to live in another lovely part of the country , it will cost me money for the property but also cost in terms of leaving friends behind. it might also cost in terms of inferior transport facilities and the dependence on a car.
For instance, I would love to live nearer the DDs in London, but the cost (as well as bring prohibitive) would include being further away from the other DGcs in Birmingham.
In the same way if I were to choose to go and live in another country the “cost” may include reduced access to my children and grandchildren, the vicissitudes of the exchange rate and lots of things like the language, local habits, health insurance, driving licence, administrative details etc.
I imagine you factor those into your decision making, bearing in mind that life can bowl the odd googlie.
So while I am sorry for anybody who chose to buy in a cheap part of a country and then can’t resell their property because nobody wants to live there - well why was it cheap in the first place? The same applies in the UK. If you see what I mean.
Nothing is for nothing.
