Thanks for the help so far everyone. Some more details: I do not plan to buy the first horse I meet and I am getting reccomendations for horses through my trainer. I will take 1 lesson a month and the horses I am looking at have had their shots (wormer, coggins etc.) I live in minnesota and am boarding my horse at a stable down the road. I already have my own saddle, pads, blankets, brushes, bug reppelent, shipping boots, hoof pick, halter, bridle. The cost to board is 200/month (includes feed). I know what his teeth will cost. Thanks for the help, keep commenting!
Horses get spring and fall shots every year, and need a new coggins every year so these are things you are going to have to factor in, and they do not come cheap and it doesn't sound like you're experienced enough to be able to give them yourself, so it is going to be a vet bill. Also, a horse should be wormed every 2 months on a rotating schedule (I rotate between strongid and ivermectin) or they can develop worms or other internal parasites. Horses are expensive, and the vet bills really rack up, tomorrow my pony is going to be getting her shots, coggins, and her teeth checked (and possibly done). And she is going to need her shots again in the fall. And then next year, she's going to need them all again. The bills will pile up too, my pony gets her shoes at the beginning of next week. So you really need to be prepared to handle these sorts of situations (and bill pile ups).
When getting a new horse you will need more than one lesson a month to start out. I'd suggest for at least the first month or two getting 1-2 lessons a WEEK until you learn how to ride your horse (as each horse needs to be ridden a little differently and like/dislike certain things). You first horse is an experience you should go through with your trainer and work with closely with your trainer. It's best if you get help from your trainer on a weekly basis incase your new horse does something you don't know how to handled you'll be able to work through it and keep working on it weekly.
Also, just because you have your own saddle and bridle, doesn't mean they will necessarily fit your horse. Saddles are definitely difficult. I had to sell my saddle and I tried probably 20 saddles before we found ones that worked for her. I've also had to buy 2 new bridles for my pony (on top of the 3 I already owned) because her head doesn't fit every one correctly. Sometimes she's a cob and sometimes she's a horse (head wise).
That's also the same thing with the blankets. Just because you have a horse blanket, doesn't mean it's going to fit the horse that you're going to buy. What happens if you get a horse that wears an 80"-81" blanket and you have a bunch of 75"-76" blankets?
Please don't think that the horse that you're going to buy is just going to fit into the "mold" that you already have (blankets, saddle, bridle, etc). You could buy a horse and have to buy new EVERYTHING.
And as I said before, I highly doubt that you'll ever find a barefoot jumper (or at least one that will pass a vet check).
