Ken – re. prices, I have no knowledge what is the norm per square metre in the Murcia area. Perhaps one of the agents from the area can advise?
Katy’s advice is sound – maybe good at least to consider a development that is up and running where you can see what you are buying?
It certainly is a buyer’s market at the moment – you would be in a very good position to have the pick of the bunch re. unlived-in re-sales, and to negotiate a good deal.
