I have to ditto 48horthfarm and while the words sound very strong, they are very accurate.
All too often us long timers see folks desire for horse ownership cause ultimate heartache for the new owner and much hurt (mental and physical) for the horse because the person has "bit off way more than they can chew" on a daily, life-long basis.
That can mean financially, time required to care/clean the horse and it's living area, and just general basic knowlege of the minimum of proper horse care.
Taking care of an 1,100 lb piece of livestock (horses ARE livestock even though we don't treat them that way), is not even on the same planet as caring for a dog or cat.
Regarding gaited horses - that's a personal choice and one that the person's physical condition may play a huge part in. Due to severe lower back injuries, I went to gaited horses 21+ years ago in order to keep riding. I was told to never ride again but that wasn't an option and found riding a gaited horse was the answer. Mine lived with me in SoCal's Low Desert for five years before retiring to Middle Tennessee so, as with any horse, proper care in desert life is required.
Hopefully you can find a good and honest instructor to guide you along and who won't say, 30 days into your lessons, "boy have I got a horse for you". That would be right up there with someone trying to sell you the Bay Bridge in San Francisco:)
If you progress to the point you think you are ready to buy a horse, I still might not do that. I might be more inclined to ask the instructor about leasing a horse.
That way you are responsible for the care and keeping of that horse but have the opportunity to walk away if the daily grind of horse keeping doesn't work out for you. If you need to board the horse, it will give you the safety net of realizing whether or not you really can afford to pay for board, hoof care, annual shots, and unexpected medical emergencies.
The horse is still safe with it's original owner and your hurt won't be near as bad knowing you have to give the horse up because it already has its original owner to go back to.
Hope this helps - good luck in your quest:)
