Its hard to be exact as you know most banks can do low starts, special offers etc but in general our clients are being quoted a standard rate of 4.75 to 4.85 percent from Banco Cam and Banco Valenica in the south of Alicante.
Aim to get a rate no more 4.75%, one thing is for sure the banks are needing morgage business at the moment so shop around. The morgage business in Spain is changing I have even seen fixed rate mortgages, however not as in the uk. your payment stays the same and your
term changes. Lots of mortgage options to chose from so you need to do your research.
