Choosing which documents your tenant sees in the portal
You pick the documents one by one in the rental's Portal tab — nothing is shared by default.
Choosing what's visible
Open the rental, go to its Portal tab and, under "What you share", find the Documents card. It lists the documents of the property and those of this rental; tick the ones your tenant may open and download. Nothing is ticked by default, and enabling the portal shares nothing on its own.
If a document is missing from the list, upload it first to the property's documents or to the rental's — the card links to both. The "Tenant view" preview shows what they will see before you open the portal.
Once the portal is open, the tenant activity card tells you when your tenant came in and what they downloaded. If you close the portal, they lose access at once; what you chose to share is kept for when you open it again.
The "Publish to portal" option of a document (the "In guest portal" switch) is something else: it only appears on short-term rentals and belongs to the Guest Portal, for your guests. It shares nothing with a long-term tenant.
