You want to exit the property lot. What is the right thing to do?

Your answer is fully correct, and here is why:

When exiting a property (like a parking lot), pedestrians on the sidewalk or crossing the exit have the right of way. You must wait until they have completely crossed before driving off. This ensures their safety.

However, if the pedestrians give a clear signal, like waving you to go, you may proceed earlier. This polite communication indicates that they are aware of your intention and agree that it's safe to move.

Using your horn to urge pedestrians to move or give way is not appropriate and can be seen as aggressive. It does not give you any right to proceed sooner.

Remember, in Germany, pedestrian safety at exits is a high priority, so waiting patiently or proceeding only with their consent is the correct rule to follow.
