Summary
When you list the same property on multiple channels (for example, Airbnb, VRBO, Booking.com, and Direct), you need every channel's calendar to update the moment a booking comes in on any one of them — otherwise you'll end up double-booked.
Host Tools' availability syncing solves this by treating each connected channel for the same property as a single listing. As soon as a guest books on one channel, Host Tools blocks those dates on every other channel automatically.
💡 Pro tip: Despite the article title, this isn't about syncing two different properties. It's about syncing the calendars across multiple channels where the same property is listed.
Turning on availability syncing
Before you start, make sure all the channels for the property are connected to the same Host Tools listing. If a channel is showing up as a separate listing, follow How do I connect a new channel (Airbnb, VRBO, Houfy etc) to a listing? So Host Tools recognizes them as the same property.
Click your profile photo in the upper right-hand corner.
Choose Settings from the drop-down menu.
From
Settings > Listings, find the listing you want to sync and click its Settings button.Turn on the Enable Listing toggle.
Make sure the Messaging Only toggle is off. When Messaging Only is on, Host Tools won't sync availability or pricing — it only handles automated messaging.
Click Save.
Going forward, every new reservation on any connected channel will automatically block those dates on all the other channels for that listing.
Host Tools becomes your parent calendar
Once availability syncing is on, Host Tools becomes the source of truth — the "parent calendar" — for that listing.
⚠️ Important: Host Tools only pulls actual reservations from each connected channel. It will not recognize manually blocked days on those channels and will reopen them. Any dates you want blocked must be blocked directly on the Host Tools calendar.
Does this sync availability between two different properties?
No. This article is about a single property that's listed on multiple channels. If you rent out a whole house and individual rooms within it, that's a different setup — see How do I sync availability if I am renting out an entire house and rooms within the house separately?.
What if I only want Host Tools to handle messaging?
If you'd rather manage your own calendar and pricing on each channel directly, turn on Messaging Only, and Host Tools will leave availability alone. See How do I use Host Tools for Messaging Only? for details.
