Make sure you ride him in an arena if they say he can. Ride on their trails if they say he trail rides. Ride for 30min or longer. Call their vet and make sure his vetting is up to date.
His feet look good for a draft, many people let their feet go to heck just because they are a draft...
I don't see any white hairs from bad fitting tack, so that's good too.
Three grand for a horse is way tooooo much around here!!!
Most are free cause of the cost of feed and related care, and you can be sure this baby will take a lot of feed.
What everybody else said...beautiful horse, money burner etc.
Moneywise you can expect to spend about double on a draft horse that you would on a regular horse. Feed of course but also tack. Talk to a shoer. Around here it's double to triple to have a farrier trim or shoe a draft. If you have the extra cash to balance out the fun of owning a draft and everything else checks out okay on him, then I would never tell you not to go for it. Personally I would love to have a draft horse.
Practically speaking, and as a friend, I would advise you that this horse is way overkill for you. If you are serious about being a horse owner and learning how to ride I would seriously tell you to first take lessons for 6 months to a year. Then you'll have a much better grasp on the reality of how dedicated you will be to actual horse ownership. Then you would probably be happier with a less substantial animal. You know, one that you can saddle without using a high lift, and get on and off without a handy loading dock.
I don't want to throw cold water on your enthusiasm, but if you truly must have a horse (and I am one that does so I could be an enabler ) there are many excellent horses out there that would suit you perfectly when the time comes to commit. You will want a been there, done that horse that you can learn a lot from and will keep you safe.
Good Advice from @thistlebloom My cousin owned a Percheron he was a sweet soul. I do not remember him being this BIG. Never having owned my own horse and always wanting one (A big one, too!) I am tempted to say go for it. but think taking lessons and learning more about time commitment, expenses involved etc. is a good idea.
1st - a Percheron could carry 2 of you.
2nd - what Thistle said. If you are a complete beginner, take lessons and become a barnrat (hang around every chance you get) for at least 6 months first. There is a LOT more to owning a horse than just riding. I'm not trying to discourage you - it's a WONDERFUL experience - but I've seen so many people spend the money to purchase without ever considering the feed, time, wormer, time, hay (that boy is going to eat a LOT of hay - ie 1/2bale a day in the dead of winter), vaccs, time, hoof care, time, fly spray, time, blankets... not to mention all the time that will be tied up in his care.
Oh - and that 6foot that secuono mentioned is at his shoulder - his back is 6feet off the ground.
This might ease your mind a little - I'm not very far behind you weight-wise and my Thoroughbred - all spindly legs and long back - had NO TROUBLE not only carrying me but jumping, hoping, bucking, leaping sideways to avoid invisible buggers, rearing now and then and running laps in the ring until I was tired of sitting on her. A good lesson barn will match you with a horse, body AND mind.
Thanks guys had a long talk with Kate who is buying farm . Funny I remember her as a kid ( parents clients over 30 years) She made me swear (I think I have to sign in blood) That I would not even THINK of buying a horse till I have been taking riding lessons for a year. Monday she closes, when she is all set up i will start taking lessons from her, she promised me she had horses that wouldn't be abuse if I rode.
Remember Hoss Cartright? No small fellow there, and his ranch/work horse was no bigger than his father's. Little Joe had a smaller quarter horse than the others.
