Hi Lacey - in case you are still reading this I just wanted to add my two cents worth also.
Like you I am sorry you have to think along these lines but understand needing to move your horse. I obviously don't know your area but around here the auctions are not kill oriented - one of them is a major place to find a decent horse at a reasonable price.
In Jan one of the boarders sent her horse to auction (for many reasons) - the horse acted up in the ring and only brought about $300 - then part of that goes to the auction house and to the person who drove the horse there and I think someone was paid to take the horse into the ring as the owner and hauler couldn't/didn't want to.
Anyway, I asked my knowledgeable BO at the time if the horse would go to killers - he said it was unlikely - generally he has noticed the horse gets bought, worked with a bit and then taken to another auction and resold there. I didn't think that was too bad.
As for re-advertising Ace - start all over with a fresh start date - do not just renew your ad b/c if your horse has been for sale for a long time buyers will suspect something is up with him. Not trying to be dishonest here - just helping you sell b/c everyone looks for something different in a horse so you want to make the best presentation possible. As I was horse shopping I also noticed how goofy sellers are (not you of course

) - they don't reply to me at all, they don't answer my questions, they have no pictures, they don't expect us to ride the horse when we visit, they have an unhelpful, ungracious attitude - very odd!! Just be your nice self and make the visits easy.
About selling at a lower price - you will get a whole new group of lookers. For example one of the boarders at our barn buys the least expensive horse she can find b/c it costs so much to keep them (board, vet,incidentals, etc) - and she takes very good care of her horses and is very good to them. I tend to also look in the lower price ranges figuring there are always hidden gems. So - just saying I think readvertising at a lower price is a good idea.
Good luck - I hope it all works out well for both of you.
When I count my blessings, I count my horse twice!
