After having invested in many properties in Central and South America, my best advice to start is to set your personal investment goal first. What wort of property are you looking for? Residential house? Condo? Apartment? Commercial Property? Do you have a bank account in Spain already? LOCAL real estate professional? Attorney to help guide you? Have you been to Spain already? Most of the very best deals and professionals are not found on the internet but by visiting the local areas in Spain you are considering and asking around. There is no substitute for this boots on the ground due diligence. You can make money or lose money in any area of Spain, you must first know your investment goals and criteria and how this will fit into your current lifestyle.
This is something I would love to talk to you about if available.
