Check our two interesting papers: “Madrid Case study” and “Barcelona Case study” by Pierre and Raf our property hunters in Madrid and Barcelona. Both have a strong team and are active since more than 10 years.
It’s very good to do it all alone, it will take more time but it’s fine. But, don’t make the same mistake as many foreigners (and one of our partner 😉 ) NEVER BUY – SIGN ANY CONTRACT IN SPAIN WITHOUT AN INDEPENDENT LAWYER! That means another one that the one provided by the real estate agent selling the property!
Don’t get stuck in a bad deal, it will cost you much more than an excellent lawyer.
