As long as you are mentally prepared for it to go either way, I don't see it as a bad thing. Three of my current four horses were purchased sight unseen and transported to me from halfway across the country. I had a LOT of phone calls with the seller, she was very happy to help and answer questions and very instrumental in arranging the transport (something else I had never done before). She also put me in touch with several references of other people who had bought horses she had bred. I did have a vet check on the three horses before the sale. That being said, I have a mixed bag as a result. My gelding far surpasses what I had hoped, he's amazing. My colt was a little wild indian and took a lot of work, however now he is priceless and I have high hopes for him as he matures. My mare, however, was in deplorable condition - while not sick, she was so skinny and in such poor shape it's clear the pictures I was shown of her were "old" ones. I think if you go in with your eyes open and aware of the risks - it's a chance worth taking.
