- Go to the listing and click Pricing & Availability.
- Scroll down to Calendar Availability
- Click edit next to Availability Window
- Here you will find a drop down menu where you can change the availability from 6 months in advance to 12 (or for all future dates, but I wouldn't recommend that!)
Another option is "Unavaible by Default" However, you will need to manually open dates you would like to rent. This method is useful if, like myself, run a seasonal cottage.
