There is a brand new website promoting winter lettings in the Algarve: www.winterinalgarve.com. The site contains lots of information about spending winter in the Algarve and home owners can advertise their property for letting.
Advertising on the site is free. The purpose of the site is to attract more guests to the Algarve in the quiet season, thus promoting the Algarve as a year round destination. It also contains a section that explains home owners how to rent out their property, as they often underestimate the perks of winter lettings.
Though revenue is likely to be lower than in summer, the typical winter guests stay longer and are often pensioners or early-pensioners that take very good care of a property.
WinterInAlgarve is for now only available in English under the .com and .co.uk extensions, translations to Dutch with the .nl extension and German with the .de extension are foreseen for April 2017.
