If your thinking about selling and buying horses right now...no the market is at a low right now, around where I live you can buy a horse at the same price that you can go and see a movie and have a good dinner after words......what are you lookingat doing with horses?
Yes, what are you planning on doing with your horses? What disipline, or are you starting up a riding school. If you where planning on breeding, (starting a stud farm) yes there is money in that, but you have to understand its not as easy as it looks!! You have to breed for Temperment, looks, conformation. All that can be quite confusing when you aren't expirenced in horses.
If you mean competing, then yes there is money in it. But not enough to make a living unless if your really good. But still everyone has there bad days.
Please discribe what kind of buisness you are interested in...
