As far as I know you can't cancel a property as such, you will just need to close all the available dates and rooms etc. But perhaps you can try contacting Booking.com and asking them what the best option would be?
On your Extranet go to ->Inbox ->Booking.com messages.

Hello,
You need to call BDC support line in order to get this processed.
