Thus probably should go over on the Western Forum but I don’t think the basic question has a different answer in any breed or discipline.
The answer is it depends on the seller. IME Breeders are less likely to want to dicker with buyers over price. Breeder knows exactly what they have into the colt, they keep it right at home and they know what its relatives have sold for at similar age and training level. They might expect and be willing to do a little negotiation but are more likely to offer free delivery if it’s easy driving distance, throw in a Halter and blanket or something like that rather then a agree to a significant price reduction. However most Breeders don’t mind if you ask them if they know of others of similar breeding closer to your price range-most are helpful.
Your best prices are going to be in situations where an owner no longer wants or can afford the horse boarded at a commercial barn. Those people have to sell, they have no place they can afford to keep it…sometimes they call the breeder to see if they can help with finding a buyer.
So it never hurts to speak to Breeders but dont go look at a 10k colt if your budget tops at 7500…but you can call or e mail a question about others that might be closer. They can chose to help you or not without wasting either sides time.
Need to add don’t get seduced by a big name sire that’s heavily advertised. The dam carries it to term and raises it the first 4-6 months, she’ll imprint it with her “personality” and attitude. Many Breeders in most breeds value the dam side over the sires side in predicting trainability and attitude. It takes two good ones , not necessarily great ones, to produce a good one. Look for that, not a great sire and a so so dam who is a witch and never did anything because nobody could stand to be around her…like I bought. But I’ve been at this a very long time, it was a very successful Hunter and the price reflected the inherited bitchyness.
Generally recommend staying away from very Green youngsters unless you include the training from a qualified Pro in the budget. No offense but many overestimate their skills at training up a young horse if they have never done it before. They also forget much of the value in a well known stallion, especially a QH, is the way he was cared for, trained and shown, the nurture part not the inherited nature. Bloodline alone can be misleading.
