Yeah the team being significantly better should help the demand/resale value, but a lot of it depends on which games you're choosing to go to/list as well. In our plan, we always list Cubs/Sox (I personally hate going to those), and try to list some games in the Yankees/Red Sox tier of teams. Date of the game is also important as well, early season games tend to do worse than mid-summer ones. Generally we just use the profits from what we sell to help cover the expenses of the tix we have, very rarely have we had to eat any tix.
