Popping in to say that at the $25k range, you can get what previous posters have said in a Warmblood (2-year-old/unbroke or something with a massive quirk) OR you could get a VERY NICE OTTB/TB. Like, a completely finished, perfect, “any dummy can ride this” horse.
Obviously OTTB’s and even sport-bred TB’s are not the breed du jour at the upper levels of this sport and it can be VERY difficult to compete against the purpose-bred WB’s at the big A shows. And that’s not taking into account the high level riding at those shows, as well.
I personally will never consistently be in the upper levels of this sport due not just to money but also to skill, and that’s totally fine. I didn’t have a NEED for a $50k+ horse, so I went the considerably less expensive TB route.
I paid under $25k for my guy. Green. No show experience at time of purchase. He was doing small courses with a lead change that needed finishing. I didn’t try him out (you might be able to make a deal if you buy off a video). He has TONS of chrome. I think his looks/build plus his sensibility are what contributed to his price tag. I’d pay it again, too!
You didn’t ask for this, but this is something I wish I was able to think about with an unfinished, green horse (I don’t regret buying a green horse/I wanted one and wouldn’t trade mine for the world, but I also just didn’t expect this experience):
It really comes down to your goals and where you see yourself; that’s where you’ll be able to determine your budget. Riding ability counts, too - this sport is so mentally taxing. If you can’t handle green/quirky behavior for a long period of time, don’t buy the green horse because he’s going well at the time. My guy is green, and has been great. HOWEVER - we’ve had a very challenging winter. I think I’ve finally figured him out, but I’d be lying if I said it wasn’t heartbreaking to go from riding small courses to only doing flat work because he started to get fresh as the days got cooler and I haven’t been able to work him much. I can sit his bucks, but would prefer he didn’t throw his body around. We’re trending upward now, but I thought I got an “easy” horse at first when I bought him late spring and went on to have a pretty fabulous summer show season at the local level with him. He humbled me so fast!
Always remember that a $100k horse has the same risk of going dead lame one day as a $1k horse.
