@Stephanie1842 For most hosts, very few inquiries, no matter for a month or 4 days, result in a booking. An inquiry is just a way for a guest to ask questions and they may have sent out inquiries to 20 different listings.
It's best not to waste too much time responding to inquiries- briefly answer their questions and move on. And you don't have to either pre-approve or decline an inquiry. A response within 24 hours is all that's required.
