How long do I have to wait before I can sell my investment in Portugal?

After obtaining a Golden Visa from Portugal, when can I sell my investment without losing my status? Do the required maintaining periods vary with different investment options?

Answers

On Nuno Albuquerque answered:

In general, investments must be maintained for five years. Only after that we advise selling the investment.

On Diogo Capela answered:

The investment must be maintained during the five years of the Golden Visa Program. At the end of the fifth years, you can choose to obtain the permanent residence permit or the Portuguese nationality. By then you will no longer need to maintain your investment.
