I was thinking about doing the same thing at the same time coincidently!
I have done abit of research, that may help you;
Housing; rightmove.co.uk offer a range of overseas property to buy. Other usful websites are;
http://www.tenerifepropertyconsultancy.com/areas.html and
http://www.propertysalespain.com/search/52/363/Playa_de_las_Americas_property.html. Just typing into google 'property for sale in Playa De Las Americas' or something along them lines should get you a fair few results! I have also read in other threads that 'Visa Verde' is a good company to buy property with out there! Or if your looking to rent a good place to look at is holidaylettings.co.uk; some of the properties on there are rented out at 6 months/12 months or any long term let, and although seem expensive, can include all your bills! Or again just type something into google!
Jobs; I have found a good website (
http://www.lovetenerife.com/moving_to_tenerife.html) and they offer all information about moving over, but also they advertise jobs, and also links to website that offer a wider variety!
Hope this helps!
If you want any more info, just ask and I will try and do my best to help!
