There is a slightly different climate in the Bay of Biscay because if it's location. There is an oceanic climate here which means the summers are not quite as dry as the rest of Spain. This is more than made up for by the beautiful scenery and culture.
There are many types of Spanish property from traditional Spanish homes to modern apartments and resort villas.
You will need is an NIE which is a tax identifier for Spain even before you find your chosen property. You can get this from the local tax office in the area. This will also be required to open a Spanish bank account.
The good thing about purchasing property in Spain is that large high street banks have partners in Spain which means you can get an easy to understand mortgage to finance your property purchase. A 10 percent deposit is payable by the purchaser once the initial contracts are signed by both parties.
You will also need to consider additional costs such as VAT and Stamp Duty. Much the same as purchasing property in the UK.
