Absolutely. Fwiw, $15k is findable through word of mouth in my neck of the woods. It will be a 4th-FEI level capable horse. It’s going to be a situation like @bouncytrot describes: *“My horse’s owner has said that she would never list him for free lease or even paid lease because she knows that people would be fighting tooth and nail for him and that it’s possible he could go to a less than stellar home who was just looking for an upper level horse as a ticket to medals but not necessarily keeping the horse’s best interest in mind. He’s an older horse and he does require considerable maintenance. He is also very much a “one-person” horse…” *
I care leased a ridiculously fancy PSG schoolmaster. He’d cost like $75k exclusive of import as a youngster & had what must easily have been $100k worth of training, much of it from someone you’ve definitely heard of. The catch? He was also a walking miracle of modern veterinary technology. His shoes alone were $275 every 4-5 weeks. Adequan injections 1-2x a year. Body work, supplements. A very precise conditioning program in order for him to stay strong enough to do his thing. I had to pay for training rides for the days I couldn’t make it out.
I presume the sky’s the limit for PSG+ schoolmasters still capable of that level in competition. The OP didn’t indicate she necessarily needed that, though. Bottom line, be looking at ads every day. Make sure you’re in a program with a trusted trainer. Be ready to move immediately on any prospects. We got our lovely new horse, a teenaged import who is a 3’-3’6" packer & seems to have seriously nice dressage training to boot after our trainer moved heaven & earth to get us in as the first test ride. Someone else swooped in with an offer off video, then – fortunately for us – backed out. He was ours if we could get him vetted the next day. Trainer worked the phones & managed to line up one of the two best practices for PPE in the area. We even got a small discount, which I thought would be impossible given the interest in the horse. Trainer said she’d ask on the basis of the PPE findings on the theory we could use the savings for maintenence. To my surprise, they said ok. Anything to have him sold & not have to field a 100 inquiries a day after him.
So, you just never know.
