I understand that there are both free and paid add-ons available for xenforo.... my question is, are the paid add-ons a 1 time purchase or do I need to pay a yearly fee to use them?

XenForo official addons are the same as XenForo - you buy the license to use them, and then you renew them every year for support and updates, as with XenForo itself. You can still use the addons if the support has expired.
3rd party addons have their licenses created by the author, and as such vary, however most, if not all, of the paid 3rd part addons are a one time purchase.
