Hola I note you found a villa out of your price range
Take a look at Sierra Golf near to Balsicas on the RM19 from San Javier to Murcia
you can rent (not sure of cost) or even buy a four-story house (basement ground first and roof terrace) for around €70,000
you will find you have a 20 minute drive to most of the coast
Tip try and not buy property on low ground after heavy rain they tend to flood
OK Sierra Golf can get cut off but it is above any land that floods
even Los Alcazares has flooding problems best of luck Ho try and find Cars in Spain at Torre-Pacheco Paul may take your
