I know very few people that have financed their horse. It really does not make any business sense at all.
One person I know who was starting a barn as a dressage trainer got a second mortgage on their house to buy a nice dressage horse. Of course the horse developed a bone infection and died.
I’m in the group that has not paid more than $2k for a horse. My best hunt horse was $1600 at an auction. Sold her for $7500 and the new owner was delighted. She just came back last week and bought another from me. Didn’t even throw a leg over him. Wrote me a check loaded him in the trailer and drove the 6 hrs back to Tenn. I was like “Don’t you want to try him?”. She was “no, I trust you”. Ok, that’s really a trusting person. That’s the way foxhunters are though. She knows how I ride and what I can ride and that if I say the horse has hunted, it will have actually hunted.
I’m surprised at your comment about QHs and enthusiasm. I ride paints which are basically spotted QHs. I find that they are ready for anything I ask them to do. I’ve got 5 paints. All hunt and event are easy keepers and get along in the pasture with minimal maintenance.
