Do I need to show up to close a wholesale?

This might be a stupid question, but here goes. I am currently working on a wholesale deal out of my state. Found a good property and just ran with it. My question, however, is do I need to actually be present for this closing/settlement or can I sign the necessary paperwork ahead of time and just make sure my title company is present? If this isn’t possible, is there any other way that I can flip this to another wholesaler so that I don’t have to get on a plane to close the deal? Thank you for any suggestions you may have.

I have only showed up for my first closing. All my closings are done by mail now.
