I can tell you from having family and friends who live in Alicante this much. It is not a CHEAP place to live. Rent alone could destroy you unless your employer is covering it. Not to mention all the local taxes and such that have to be paid. Despite 20+ years of development thing's don't operate the same as in the UK/other anglo countries, and you will have many palms to grease, when you least expect it.

A wonderful place, but go with as much money in your bank as you can.
