Keep in mind that a lease-to-buy and a payment plan are different beasts. I don’t know if it’s from inflation, but I’ve had to spend more for roughly the same quality horse over the past 10-15 years (“amateur” horses, ok movers, nicer jumpers, competitive at “A” shows). It used to be $20k, then 30k, now mid-five figures. Or maybe I’m getting older and am less brave?
As a buyer, I think lease with option to buy is great. Of course, it’s more risky for the seller if something happens to the horse or the horse ends not doing as well in another program. And the owner also takes the risk of having the horse returned in a year, when they will have to try to market the horse again.
ETA: As a buyer, I’ve asked sellers if they have lease or payment options available. I’ve bought one on payments over 6 months.
