I think you are much more likely to find something on a PPE that might result in a lower offer being accepted on a lower price range horse. BUT the PPE detailed enough to turn up something the seller was unaware of is probably going to cost more then they reduce the price, might even cost as much as the horse.
Dealing in the upper price ranges, these horses are vetted to death and there’s likely nothing the seller is unaware of. Any issues would already be known and reflected in the sale price.
I think initially coming in with an offer of anything under 90% of the asking price is probably going to get the door slammed in your face as far as countering is concerned. 20% under would be considered a low ball and wasting sellers time.
There are always exceptions and sales between private parties with no agents involved can be quite different…but those seller’s generally have already priced down since no commissions are involved and maybe tougher to negotiate with.
You maybe can negotiate on a house or a car but having them come down 20% is pretty rare, lucky to get 10%.
And whatever you do, don’t ask for an off the property trial and then offer 20% below the asking price.
Its best to look at horses already in your price range, not fall in love with one that’s over but you figure on a discount and get upset when its not offered. And that’s what happens too often.
Last person I knew that bought one priced at 100k got it for 92,500 with a known, disclosed vet issue. That’s because it was owners ex live in girlfriends Hunter and he wanted it out of his Jumper barn and sight. Something only another Pro would know and a good reason to trust one as an agent in these price ranges.
