Unfortunately, there are a couple things that increase a horse's asking price other then just where they are in their training. Poet's Hill is a big A show barn with lots of nice very expensive horses. A green unproven horse pulled out of a farmer's pasture (or even a smaller show barn) is pretty much guaranteed to have a smaller price tag then the same green unproven horse at a big time A barn. $35k is almost nothing to a barn like this one. It is not at all unusual for a derby horse, high performance hunter, a maclay horse, heck a large junior hunter that will win in good company to start off in the 6 digits. A girl at our barn bought a "prospect" (just started his first year pregreens) for $80k and have already had several people offer to buy him for double that. I have a good friend who just put 3 of her nice 3"6+ hunters on the market for $300,000 and have people lined up to try them. They're both horse showing in Florida for the winter. It's a different world. It's absolutely ridiculous really, but it's the reality of the world.
I have a hard time really telling what this horse is worth by what little the video shows. I think he's cute, seems to have a decent step, nice mover for the hunters, cute jump, willing, and brave... if he can course around nicely with a lead change? 35k is not astronomical although I would of course offer less. If only a pro can do a course with him, if he has yet to do courses, if he doesn't have a lead change.. eh, a little green for the price. Curious to hear how the ride went.
