@Niña Phelps Niña, good on you for getting started so young! I wish I had an interest in real estate investing at your age. If you’re focused and do it right, you’ll find yourself way ahead.
I’d say the most important thing to do right now is to identify what your goals are. There are a lot of things you can do with real estate. You can flip houses, wholesale, but and hold, invest in notes, etc. There are also different vehicles within real estate - single family, multi-family, land, commercial, etc.
There are a lot of options to get involved with, and it can be overwhelming. My advice is not to try to learn everything at once; instead, pick the method and vehicle that is best aligned with your goals. Over time, you can grow to learn more and more in the industry.
Once you’ve decided what aspects of the industry will help you accomplish your goals, assess what resources you need to start investing there. Resources may be your network, funding, time, knowledge, etc. Develop a plan to put those resources in place and start executing.
You'll learn the most once you get your hands dirty. Don't feel that you need to spend months trying to narrow down your vision. Jump in as soon as you can and as often as you can (even if it is with small things like analyzing deals on the MLS).
