Cancellation Policy
How to set refund tiers for a property's cancellation policy.
On the property, go to the Cancellation Policy tab.

Optionally check Refund cleaning fee on cancellation and Refund pet fee on cancellation — these fees are excluded from refunds by default.
Click Add Tier to define a refund percentage based on how many days before check-in the guest cancels. Add as many tiers as you need; they're automatically sorted from most to fewest days, and any gap defaults to a 0% refund. The Policy Preview at the bottom shows exactly what guests will see.

Click Save Policy. This policy is what gets enforced (and shown to the guest) if a booking for this property is cancelled.
