I don’t think you should buy a horse atm. Not, that you can’t do it or anything, but after riding for a year you’re still beginner, as you said before and you would profit more form riding different horses. And you certainly don’t need a 1,10 schoolmaster from europe.
Just to give some insight: I’m riding since birth, owning horses the most part of my life. I’m jumping for ages. (I’m 29). I bought my current horse 10 years ago, before that I had some lease horses but not so much lessons, cause the leases weren’t owned by ambitious owners and so there wasn’t much possibility to ride lessons with them. That’s a huge part of the reason why I bought my mare 10 years ago. But I had been taking lessons many years and additionally was a rider even before I could walk properly. So I think, I might consider myself as advanced. (Before the leases I had my own set of 6 ponys which I was happily hacking)
After a few years of breaking my mare in and some sh*t and stuff that happend, I started jumping with this particular horse in 2017. And to this day I haven’t jumped any higher than 1,15 or 1,20 ever. I do shows at low levels (E and A, 80 to 100cm classes, german system) and I do event at the same level. So I have quite a bit of expierence under my belt.
What I want to say is: Even I would be perfectly fine with a 1,10m schoolmaster, as I’m not doing anything atm that would need a better horse. And I’m literally riding for close to 30 years. Of course, I may not be the most talented rider on the planet and my improvements are slow and I might very well be, that you are a much more gifted person and will advance to 1,10m in a few years. But still this doesn’t require a 1,10m schoolmaster NOW.
And I want to add a second perspective: You never jumped until now. So you really don’t even know, if jumping will be fun to you. Or if you are talented in it. Of course nobody needs much talent to jump a few crossrails, but it certainly takes a bit of courage to ride against higher jumps and you need a bit of an eye for this. I know many very expierenced riders, that don’t jump or jump not much more than 50cm, because they don’t feel comfortable doing bigger things.
And in addition to that you don’t really know right now, which kind of horse suits you best. How many different horses have you been riding since you started. I recommend riding as many as you can get a hold of. Because horse vary greatly in their type and how the ride. So when buying your OWN horse, you should at least have some idea about what kind of horse you like. And considering jumping you should at least know, which kind of jumper suits you best. Horses do jump differently and there are some, that I can’t stand riding, because they don’t give me a good/safe/satisfying feeling.
So as a conclusion: I don’t think buying a horse atm is the best choice for you. I would recommend leasing horse or look for a barn, that has a variety of school horses, so you can advance your skills and get more input on which kind of horses you like
