Buy-and-hold At €1,320,000, the property is near its fair value, which may limit immediate return potential, but it offers stability in a suburban area of Greater Lisbon. The appreciation potential remains moderate, and holding for the long term could yield satisfactory results given current neighborhood conditions.
