I'd have a look in Guardamar - I bought a flat near the sea 18 months ago & been offered 30k more than I paid for it. I do not rent it, but I did buy with that in mind for the future - the rental sites tell me I can get between €650-€850 per week peak season (3 bedrooms). Very popular with many Spanish & Europeans.
Spanish properties can/do go up - but you need to be careful where you pick. Nearer the beach in popular rental locations. Also beach properties or those with something 'interesting' will sell/rent - you just have to avoid the 'me too' type properties. At 50k you may find a one bedroom somewhere a few blocks back from the beach in Torrevieja - not sure Guardamar, possibly.
A friend of mine has also bought a couple of properties in Alicante city for around €30k each, let out instantly to local workers. At 30k a pop, they can't go down that much & he has done this with the long-term view for pension.
Moncayo properties Guardamar are quite helpful if you want to look in that area.
