Complex charges payable quarterly (includes water rates / TV): €286
Council Tax (Consorcio de tributos de la Isla de Tenerife): €166
Electricity (average monthly cost): €30
AVERAGE MONTHLY COSTS = Less than €140 per mont
For me, as an individual, I usually make four visits to Tenerife per year, spending approximately twelve weeks here, mostly in the winter months. Assuming an average flight cost from the UK at £80 return (the last few flights I booked cost me £76 return, or €100), then each week in Tenerife cost me £120.33 or €156 (if the property increases in value by inflation or just 2% the costs are more than covered: a good investment).
Of course these costs will be far less if split between a couple or more.
