@Dylan Tettemer I would agree with @Bram Spiero. Find the target market you want to invest in and start learning about it. Building a foundation of understanding your target market will be a great benefit if and when you move back to the states. What niche are you looking to get into? Buy & hold? Rehabs? Wholesaling? etc.
I'd also suggest finding ways to save a little bit of money from each paycheck so that you have some capital to invest. It doesn't have to be thousands of dollars. Even just a few hundred bucks will allow you to get started with a bit of marketing to generate some leads and allow you to get some experience in talking with potential sellers.
The biggest thing is to not get discouraged. Understand that real estate investing is a marathon and not a sprint. Don't get caught up thinking you'll catch the express train all the way to the top. While some people do have great success right out of the gate. That is uncommon. For most people it will take some time to get to where you want to go whether it's in real estate or not. The success stories always make it sound like everyone is an overnight success but in reality there was a lot of work involved and even more time. Just stay focused on your goal and take action everyday to move you one step closer to your goal. Whether it's reading or talking with other investors, just do something each day. I'm fairly new to the arena and have done a few wholesale deals but am happy to help in any way that I can.
On a separate note, I noticed your in the Air Force and wanted to say Thank you for your service. What's your AFSC?
