Hey @EmpiricalStomach63, thank you for the question! I answered another question regarding prepaid resis here: https://appointmenttrader.com/sellers/discussions/sellersfaq-178-exploretock-reservation#Community TLDR: AT will add a category for prepaid reservations which will let you set the value of what you have prepaid which will then create a 'bid premium' + equity value of your reservation. At the moment it is all-in. You can upload the reservation and set the asking price in a way that will satisfy your entire expense. Hope this helps!
