I think we are on opposite ends, but we both wish for a simpler solution. I rent out cards primarily. I would rather not have to cancel and re-rent cards throughout the season, but renters don't keep cards rented all season even at a cheap rate. So, I find myself stopping rentals 6 days before EOS and then relisting at 6 to 8 times the rate I was renting. I think a guarantee lock on the rentals would be nice. If I knew that the rental wouldn't be canceled, then I would be happy to tie a card up for 20 or 30 days at a fixed rate. I think the renter would like this also, but currently there is not much penalty for either side to cancel the agreement and move on to either another renter/rentee.
