Only assuming you and your wife are still working. If that’s the case do as others have already said, ..don’t rush into buying anything. The cardinal rule.
Monitor prices, use this time (maybe 2 years or more??) while prices remain depressed, to fly into different airports for short breaks, get a feel for the different areas and talk to expats and locals and benefit from their experiences.
Contrary to what’s been written, Torrevieja (and Villamartin) suits some people because of the facilities, English widely spoken and the high proportion of expats living there. Gives a certain amount of security to some. Others seek a quieter, remote and more Spanish lifestyle, depends on what you like.
My advice is, take your time to become as well informed as possible before buying anything.
