It is risky- we know the risks.
It is very very risky, do you know all the risks?
I have bought 3 horses sight unseen, and this will tell you that I am
B) A slow learner
#1 saw lots of videos, pictures talked to the owners, they were great to work with. Mare turned up from 100 miles away, looked exactly as expected, loved her, thought I had done well. BUT, my experience level was not what she needed, still thank she was a good mare, BUT again, the person I eventually sold her too, has sold her again..very very pretty mare but very unpredictable at times. Call that one a partial success, red flag missed, the fact she was 8 years old and had seven registered owners in her life.
#2 Bought from a reputable (?) breeder, mare was not at all what I expected, right mare but her condition was horrible and her health suspect..lost her within the year, poor girl.
#3 Bought from a person I knew from online and thought I could trust, my want for the big pretty black horse overshadowed my good judgement, that is the horse that put me in hospital for a month
By contrast my trainer has found me two horses now, both appropriate for the stage I was at, bth never advertised, sold by word of mouth alone.
DO NOT but sight unseen
DO NOT buy without an experienced person with you.
I believe that you are a total beginner? Have I got that right, if so I REALLY suggest some lessons before you go shopping, then you will at least have an idea if the horse might work for you
