I think it depends on the title company used so check with them.  I used Timeshare title inc.  They sent an email with instructions and clearly outlined how the process would work. Up to 1k deposit on a visa no fees.  I gave them the number and signed a consent for them to charge and they didn't charge it until it passed ROFR.  The nice thing is that I knew right away when I passed ROFR because that's the day the charge was placed.
