Williamson gave the example of the Algarve, which she says is massively popular with tourists during the summer and also attracts golf enthusiasts all year round.

She said: "You will be in a position to benefit from a year round tourism market because of the Algarve's out of season popularity with golf tourists. This can mean you get a better rental yield in Portugal even if you target the highest priced property locations."

Williamson added that a disadvantage of the Spanish market is the fact it is now experiencing "a saturation effect" due to the high level of development the country has seen, she concluded by saying this is something that is yet to affect Portugal.

Property inspection company Sunscape Properties predicts that tourism in Portugal will increase by 300 per cent in the next seven years.
