My family have owned property in Spain since 1981 so we have experienced many highs and lows in the property market. I have lived in Spain myself since 1996 and have my businesses here and in Italy. The Spanish property market had risen at an immense rate driven largely by overseas investors. The grossly inflated prices you experience in the UK has definitely been seen here in Spain also, and that kind of growth could never continue.
Prices are coming down, and as in the UK , there are great bargains to be had. However if you are buying for investment then it should really only be a long term investment ie 5- 10 years as the property market here will take time. Spain is still the no1 holiday destination for the UK and Ireland, so it will always have a market, although will be greatly effected amongst other things by the drop in the pound. The most desireable locations are not dropping at the rate we see in areas such as South Costa Blanca, and whilst there are bargains to be had, the real bargains are the repossessions.
Bank repossessions in Spain are more complex than in the UK and whilst many many agents use this in their marketing, very very few of these will be the repossessions they claim. You need the full amount in cash though to buy in this manner and therefore the hugely discounted properties will only be available to a small few. The only way really to get to hear of these types of properties is by being here and in the business such as myself.
It would be lovely to have a crystal ball and know how much further the market could drop but one things for sure, the majority of foreign purchasers here in Spain would have had to put in around 30% of their own money initially, which is a lot harder to walk away from than if you had a 100% mortgage on a house as in the Uk. The trend for most people is to find a rent for their property and if they can, to ride the storm. Long term rents are not two a penny here but as most spanish have been forced out of their own property market, there is an increased amount of Spanish renting. Time will tell, and I think we will all be a lot wiser for it.
