I totally agree with your comments.
I speak a bit of Spanish ,i lived in Barcelona in the 80s and my brother has owned a property in Benitachell for 10 years so i have learned quite a lot about the area.
I am under no illusions that its a question of learning but you have to start somewhere. We have a very successful family business in the UK that was mine and now owned run by my brother,that involves bucket loads of customer service that is how the business has grown i feel that bringing that to any business is a major factor between success and failure.
All that said the estate agency is still just a possibility ,we do have some other ideas.
Many thanks again Jo
