DEFINTELY RENT for at least 6 months or at least one winter in your preferred location. Get to know the area and the neighbours and they will tell you if it is too cold for you in the winter etc etc. Renting here is always money well spent. If you do not like Oria then you can move to another warmer (or not) location virtually hassle free whereas tipping your life savings into a property then trying to sell again can be VERY expensive and problematic.
Food for thought?
Albox area is certainly warmer on average than up near Oria.
