@Rick4126 Not sure if I understand your question, but you can list it and block all the calendar dates up to May. But a consideration is that renos often take longer than anticipated, so you don't want to get into a situation where you have bookings that need to be cancelled because the place isn't ready yet.
If it isn't guest-ready, it would be difficult to have a photo gallery (and guests book to a large extent based on the photos) that does it justice.
