mortgage for non residents (Barcelona)

Hello everybody,

I am Swiss resident and I have purchased an apartment in Barcelona using a personal credit. Now I am looking to get a mortgage on the apartment so that I can cancel my personal credit.

Could anybody advise me which bank could offer a mortgage 70%-75% of the value of the apartment. I know that some banks only offer 60%. Any contacts in a bank would be highly appreciated.

Thank you very much and kind regards,

Antonia
