Glad you're going to continue looking OP and leasing is a fantastic option. My first really great horse I owned after leasing her for a few years so something like that could end up working out for you too. Also, and this is just from what I've seen, for a completely beginner safe horse even in a more common breed like a QH or Paint, you're looking at around $3,000 for that kind of training. Anything significantly less than that I'd be suspicious of. Always always always though take a trainer with you to evaluate the horse and then do a pre-purchase vet exam, even if the owner tries to give you the horse's entire life history of vet records. You still need your own vet.
