Are you buying to resell or buying to form a relationship?
I look at my horses as my long term therapy, vs resell or can I recoup my cost. They are horses, I plan to loose gobs of money. If I set that expectation with myself, there is little room for disappointment. My enjoyment and happiness is priceless.
One thing helpful for me to buy a horse is whether I would be happy to see their face greet me over the stall door and as weird as it sounds, they speak to me. If they speak to me, and I have an open stall/budget I’m probably going to at least inquire about them. If I showed anything more than local non rated, I’d probably be pickier about said horse, but life is too short.
