Hi,
I have lived in Corralejo in the North of Fuerteventura now for nearly 2 years and love it, I have taken my kids on the plane to Tenerife and yes the north is very Green and beautiful, however for good reason, the cloud is held up by Mount Teidi, Spain's highest mountain, this means although temperatures are warm, it is mostly cloudy hence the green fauna. Personally I love the sun so would not choose Puerto de la Cruz, but only for this reason as I found Puerto very beautiful and has more sophistication and culture than Fuerteventura.

Work in Fuerteventura is very poor at the moment and those that even have skills are leaving by the droves at the moment as there just is not the work to go round. No point looking to buy a bar or restaurant here at the moment as they are all either losing money from previous years gone by or worse still going out of business. The current exchange rate is not helping this but is not totally to blame. Statistics for the islands visitors shows an increase, this is true but a decrease in British! Too many properties and not enough demand make it a bad time to buy (short term).

Personally I have a lot of faith in the long term, I remember Playa de las Americas (Tenerife) as achild when I used to walk the mile from Las Americas across the desert to Los Christianos, to buy bait for fishing,(25 years ago) now look at it. As,ong as the sun is in the Sky and the long term economy of the rest of Europe matures people will want to have holiday escapes here.

With regards to building, you can build what you like(within reason) as long as it is on a plot designated for building and there are plenty of those. (Check out Villaverde this is Fuerteventuras Beverly Hills!)

If you are retired and pay social security you are entitled to full heath care, you can draw your pension over here and also a lot of other benefits that are provided in the UK can be bought here. My parents retired here over 10 years ago and they enjoy full pension and health care here.

My Mother would never return to the UK as she has a huge network of ex pat Friends here who socialize together. (She is 70)

My biggest recommendation would be to if you can keep your options open and rent your current home out for say 12 months and come and rent here for 12 months, this way you can take time to decide.

Regards
Adam
