The Canaries are one of the only places in the world that have made private letting illegal. You can go out tomorrow and buy a cottage in Cornwall or a gite in France and will not be hounded out as illegal if you have the audacity to let it out! The Canaries Government is cutting it's own nose off to spite it's face but
I am very sorry to have to correct you on this, you are completely wrong!
I am involved in Letting to tourists,(not in the Canary islands) over three months there are few problems, short term is another ballgame altogether, (whatever eu country) there are various factors that you must adhere to ie, access, fire safety,personal safety, full liability insurance the list is endless if you do it legaly.
There is also another consideration, anyone who bought on a residential complex bought because they wished to live part of the year, or retire, and were assured of peace and quiet during their stay. ie, no pissed up tourists at all hours destroying their dreams. unfortunately the illegal let brigade, who pocketed the undeclared income have spoiled it for the few honest people.
As is the norm, some of the real estate sellers are in colusion with local lawyers, a lot of back pocket cash has been received, some buyers have been duped, misslead, conned read what you like into thinking they couls let out to tourists, the fact is this, with various countries in reccession, laws are being enforced, like it or not, they want their pound of flesh.
As it has always been, buyer beware!
Personaly, as a winter visitor to Tenerife (back again in Feb) I do feel sympathy towards the Los Gigantes area, the sooner this mess is cleared up, the better the future of the local inhabitants. We have seen a steady decline over the years, in fact the evenings have been like a ghost town (last year)
I do wish Los Gigantes well
