Hi Sandra,
I personally feel it's the bank whos selling them so they can start paying out to people who've gone as far as me! Maria and co won my case in December and I'm still waiting after starting litigation more than seven yrs ago.
I still have much to do but am relieved I've now won THREE court cases...and I'd love to go up against Sol Mijas Developers SL for the first to court costs! (especially considering they appealed to try and deter me!).
Will keep you informed...I plan to help others who can't afford legal costs...fingers crossed!
