This is just what I and almost everyone else have been saying. Without scores, you’re probably just not going to get any nibbles on your ad, and any seller agent is going to take the horse around to get some scores. Very few strangers are just going to take the owner’s word for all of the questions here.
Anyone shopping in this price point is going to either think unshown horse at this level and this age either has some serious soundness issues or cannot show for some behavioral reason.
Also, this is the level and age where horses “top out” skill wise, so if you’re just someone looking at an ad, you’re going to wonder of this horse can do GP.
So you could maybe get higher 5s over time selling word of mouth but again without scores, the pool of buyers is small, and seller agents don’t like stock sitting for months.
For all of the training that’s gone into this horse and the amount of validation the owner seems to need regarding the value of said horse, I really just don’t see why they don’t pay a trainer to truck the horse to some shows?
