Possible Move to Murcia for two couples

Hola, my name is Suzi & my partner Sally & our neighbours Craig & Tracey are hoping to move somewhere Murcia/Alicante way mid this year for Craig & Tracey and end this year/beginning next year for myself & Sally.  We are keen to have a 4 bedroom, 2 bathroom place preferably with its own pool somewhere inland.  Craig & Tracey are in their early 50's & have jobs that they can move into almost immediately.  Sally & myself are early 60's and would like to do temporary work.  I am a legal secretary and Sally would like to do a small cleaning job locally.  We have researched a few things about moving to Spain and understand that it is advisable to rent for a couple of years until we are sure of where we actually want to be.  My health is slightly dodgy with cancer early 2014 (now being checked every 6 months), diabetes and asthma.  All of us have worked most of our lives and would like to wind down somewhat in nicer surroundings than we have at the moment in England.  I am keen to learn Spanish and have been practicing with online phrases and pronounciation.  We have family friends who have an apartment in Murcia and no real ties to England.  We would appreciate any advice/help from people who already live in this area.  Thank you.
