The fact that your house is closed for long periods throughout the year can pose a risk, as vacant properties have become prime targets due to the housing crisis in the country, especially in major cities.

Although recent legislative changes in Portugal protect owners more effectively, eliminating signs of abandonment, such as an overflowing mailbox or keeping the shutters closed for months, can make all the difference.
