One could do better if they consider going to the Algarve for the winter months, apartments can be rented there for as little as €350 a month. It really wouldn't make financial sense to go to the bother of purchasing an apartment when you can rent there so cheaply.
I am not talking about buying an apartment I am talking renting a decent two bedroom apartment. Retired people might like to have their offspring and grandchildren visit where they can have a holiday for the price of an off-season flight. I know of places where you could rent for €350 per month too, but I would not be inclined to stay in such places.
Furthermore, for the €600 per month rental you can have 2 bedrooms in a central location in a good Spanish resort and enjoy good sunshine while the rest of us are nearly freezing to death (if we haven't been washed away by rain) in dear old Ireland.
