What I should be doing starting out.

[Brad Tooley]

Hello, I am 18 years old and currently a senior in high school. My ultimate goal is to own multiple rental properties and achieve financial freedom at a young age in the future. I want to build a strong foundation now so that I can create passive income and have more control over my future. I plan to get my real estate license in the upcoming summer to try and get a head start on my goals. Although, I am just starting to learn many things about real estate and have multiple question. What are the best ways to start investing in real estate with little capital? How can I build my credit and financial profile to qualify for loans? Are there any real estate investment strategies you recommend for beginners? And finally, What are some common mistakes new real estate investors make, and how can I avoid them?

Find a stable job, attend college, or work part-time and do both. Live below your means, find roommates, or live with family for free. Find little ways sacrifice. Stack cash & build credit. 

After that start working on everything @David Ojo mentioned. You can't "jump" into REI until you do the other things. You're young and have plenty of time to get it right. Cheers.
