Murcia is a great European city if you ignore the sprawling ugly suburbs.
The rest of the province is desert and intensive agriculture with a few islands of interest. It’s one of Spain’s poorest and least desirable or attractive regions.
I do understand why they have tried desparately to hype the Murcian region up over the last decade and attract investment and development.
I have looked hard at it myself but I cannot see there are any sane reasons to invest or even speculate..
