While there are no additional fees associated with using the exit window feature, it's important to note that the usual 2.5% Stake exit fee will still apply (as they would if you waited for a full property exit as well).
The 7% performance fee is not applicable on exit window sales.
There may be initial transaction costs from the initial property acquisition that can reduce investor returns, but these costs are not related to the exit window feature. The specific fees and costs due for your investment will be displayed when you create your sell listing.
