@Cirilo Villar Congrats on starting the journey! Getting advice and learning from those who are already successful investors is a great first step. I bought my first duplex at 24 so I definitely know what it's like to want to start investing and buying properties right away.
There is a lot of great advice in this post already, but I'll throw my two cents in from my own experiences that helped set me up for success:
-First would be to get your financial house in order and prepare yourself for the journey ahead. Turns out real estate is expensivse! I constantly read financial books and learned proper financial habits. I learned to live off 40% of my income and save the rest, taking advantage of the fact that I was young, single, and flexible. I would recommend saving more money before buying your first property probably closer to 20-30k.
-Get a job or find a way to make a solid income while you are learning and preparing. Build a solid foundation to grow off of while you are so young. Spend that time building up savings to learn about real estate investing, network, and soak up as much knowledge as you can. There are tons of posts and resources on BP for newbies.
-Look into house hacking as your first real estate investment. That's what I did and I highly recommend it. Not only does house hacking let you get into an investment property with FHA financing (low down payments), it also helps reduce your housing expenses allowing you to save and invest at a faster rate. I bought a duplex with an FHA loan and put 3.5% down, rented out one unit, and got a roommate to maximize income. I actually cash flowed a little bit each month so I had 0 housing expenses. The equity you can build doing that combined with the extra savings potential can be a powerful vehicle for growth.
-Stay positive and keep grinding! Good luck.
