There's a term I remember well, "proud cut". I know for sure in dogs, and remember talk of this (though I have not personally experienced it) that if left a stallion past a certain age, they never lose the stallion attitude.
I've been around horses on and off my entire life. I can ride really well, I know enough to be safe with horses but I also know that not even I am ready to take on a new horse to break or train.
Mares aren't bad, but yeah they come into season and any animal in season is harder to work with because their mind is NOT on the job at hand... she'd rather be finding a guy, just mother nature at work. So you work around it and just know. They can be just fine. But it depends on the horse.
Also, you are "looking into" horse behavior. I trained dogs for years and years. I assure you all the reading I ever had was not nearly where I learned anything. It was good to have a base idea of how does operate behaviorally, but when you factor in breed type, genetics and factors we don't get to control - it's not what you think. You take a pit-bull who is genetically sound, has a good temperament and I would take that dog over a lab who's genetic background has aggressiveness in the line. Because you can't "fix" genetic problems without REALLY knowing what the heck you are doing. I mean REALLY top notch training work.
I couldn't even tell you how to temperament test a horse, I can do it with dogs but temperament is a mixture of breeding, socialization, genetics and good 'ol personality.
I think it might be a good idea to find a ranch and volunteer to work there and work along side a trainer, get the experience and knowledge under your belt. After you've got some experience, then look into this idea of yours.
Because if it doesn't go well you may find yourself with a 5 year old untrained horse with bad habits and no way to sell it.
Is there more info that might make a difference here? Do you have someone with you who knows how to train and will be working with you? Will you be boarding the horse somewhere that you can learn with a professional? That would make difference. But just by yourself as a learning experience I can't imagine that would be the best way to start.
