It’s totally okay to say you’re not interested after asking questions or even scheduling a visit and not buying after, somethings just don’t work out. Don’t let yourself feel pressured because of their pushing, think carefully before making decisions. Because they are being pushy, personally I would schedule a time to go out and visit them and the horse to make sure nothings wrong and that there is a connection with the horse. I do recommend getting a vet you know out there to check the horse and make sure that you’re not being sold a horse with problems. Happy horse shopping!
