My first horse was $100. She was solid,. hardly ever had to see the vet, easy keeper, great brain, fun to ride.
Second was an OTTB, a bit more, $800 plus $500 to get him shipped. He was amazing to ride, but I could.not.get.weight.on.him. I figured out the magic formula finally and it was something as a college kid I couldn’t afford, so I found him a home with a girl who had the money and wanted a good eventer (he could jump the moon).
Third horse was a dinky little project pony, paid $300 for him as an unbroken almost-3 year old. Literally the easiest horse I have ever had, lived on air, talented, born broke, could put kids on him and not worry a lick after one month of being under saddle. Too small for me though. He lives at a horse camp now and was leased out to a girl during the school year, competed Novice at the AECs (he’s the pony with the Auburn tiger mascot on his back that was on EN).
Fourth horse was another OTTB, about $1500 I think, most I had spent on a horse at that point. Cribber, skinny, skin issues, arthritis. Got him restarted and went to a pleasure home.
Current horse the most I have paid, $2500. I love him to pieces, he has a fantastic brain. Not the best conformation. But within the first year and a half of owning him I have paid almost double his purchase price in random vet bills. I think he is worth it though!
The super cheap ones were definitely the easiest ones I had as far as no injuries, easy care, low maintenance, best brains.
