We arranged our mortgage through our Spanish solicitor. The cost of her fees for purchasing included mortgage application and she did all the ground work and shopped around for us, filled in all the applications etc. All we had to do was send the relevent documentation over to her in Spain. She has power of attorney so was able to sign everything and apply on our behalf.
We ended up with bancaja, and so far are VERY pleased with everything. We were immediately assigned an English speaking contact at our local branch which is very handy. We can also do all our banking via the internet, which is great.
It may be worth checking if your solicitor offers this service. There are many mortgage brokers around and I would have difficulty knowing which ones to trust, although recommendations are usually a good sign.
Good luck.
