It all depends on your lifestyle and preferences. Some digital nomads get restless and change locations every few months. Others choose to settle down and stay in one place for a few years at a time.
Part of the allure of this lifestyle is having the freedom to choose where you want to live. That's why you should be careful about taking binding financial incentives that require you to stay in one period for a specific amount of time.
In some cases, it could make more sense to avoid an offer to stay flexible. For example, you might move to a new place and wind up hating it within the first year. If you already bought real estate, it's going to be more difficult to leave.
