Well, first you have to decide if you want to commit to riding them, taking care of them, and paying for feed, vet bills, and shoeing. Think about it: you should ride them/ exercise them at least 4 times a week. Do you have this time, and are you willing to devote it?

A good horse costs at least 4-5 thousand dollars. Do you have this money? You should also keep in mind that the amounts will increase over time, for the reasons I listed above. If you board them at a local barn or riding place, I'm pretty sure you can just pay monthly board, feeding, mucking, and blanketing. For instance, hired grooms there will do this for you, but you have to pay monthly bills. This is not including farrier bills. The farrier will come out every 6 to 8 weeks to trim your horse's feet and give him new shoes. Each time, this costs about 100 dollars. You should also keep vet bills in mind. For feeding, a horse (15 hh and over, sometimes less, but no smaller than 14.2 hh) eats about 10-20 lbs a day, and ponies (14.2 hh and lower) eat about 8- 10 lbs a day of alfalfa, oat, grass, timmothy, 3 way, or 4 way hay. A good bridle costs about 70 dollars, and a good saddle costs about 5 to 7 hundred. Bits, stirrup irons, stirrup pads, helmets, etc. are separate. You will also have to buy a haulter and leadrope, a blanket.... ahh, the expenses are endless, but it all pays off.

As far as housing goes, a good sized horse pipe corral is 12 x 24 feet. (rectangle). You can also see what people house their horses in at boarding barns. Some keep them in box stalls.

For brushes, the main ones you'll need are: A curry comb to get extra hair off their coat, a hard brush to brush the extra hair and dirt off their coat and legs, a hoof pick to get the dirt, mud and manure out of their hooves, a mane and tail comb/brush to get shavings out of their mane, tail and forelock, a soft brush for their face, and a rag to wipe their noses. A few other good things to carry in your tote box are fly spray, show sheen/ cowboy magic, etc. You can ask people at tack stores for other handy equiptment.

Hope that helped. If you have any other questions, feel free to ask... I've been riding for 7 years.
