My short answer is that this was a great horse to ride recreationally, for almost free....but when the situation turns to a lease where there will be more expense, your daughter needs to take another look. Based on this information, it's likely that the owner won't live up to the financial end and the horse could be up for sale by the barn owner or your daughter would have to pay the board herself. If she's going to make that much of a financial commitment, it seems to me that she should be doing it for a horse that can do what she wants to do. Sounds like this Morgan will be in a pickle for a while, but the barn owner isn't going to let him be seriously neglected, surely, for her own reputation. If the friend keeps on this path, not paying board, the barn owner can sell him to someone else who is looking for that type of horse.
