I work with two trainers. Neither of them sell horses, though they're doing their best to spread the word about mine. One my trainers would take him if she could make it work financially (and I'm still trying to poke at that option and see if I can work something out with her.)
I can't afford to lose ~90% of what I paid for him in selling him for $500. I'm not going to do that. I don't know if anyone else can afford to lose $4000 in a year and still buy another quality horse, but I can't. To be clear, I am not sending him to a rescue or anything like that. I would rather keep him and keep working with him until I find someone with whom I can reach an agreement, and/or he's at the level of training to justify what I'm asking. If the only way I can sell him is at an enormous loss, then it's an impasse, because I won't be able to buy another horse of the kind I need, and I'd rather have my problem pony than be horseless.
I'm selling him as a hunter potential because he's ribboned in hunter flat classes and has stellar knees-to-chin jump form. I'm selling him as dressage potential because we've done well in eventing-dressage and he has lovely movements with nice impulsion. He has competed and done very well in a couple of B shows, including the Half Arabian Hunter Pleasure Open last weekend with a junior rider. I'd love to take him to more shows but (let me sing you the song of my people) I have trouble affording it. I still may try to take him to the next one available.
Edit: He's not suitable for eventing because he's terrified of cross-country.
