Hey Logan,
I envy you for finding this REI bug early in life! Getting started, my suggestion would be to surround yourself immediately with those already succeeding in the real estate game. You are the average of the 5 people you hang around the most.
Don't get discouraged by those who doubt you, you will get that a lot, especially starting out. First they will laugh at you, then they will later applaud you. Again, stay away from those who do not understand or care to understand.
Personally, I would say your best point of entry will be a house hack, especially at such a young age. A house hack will bring you multiple benefits such as owning an investment property, allowing for a first time homebuyer program, learning to deal with tenants, and allowing you to decrease your living expenses.
Lastly when it comes to lenders, my suggesting would be to start attending meetups in your local area ASAP. You will either find lenders there or people who can refer you to one. Be honest and tell them you are a new real estate investor looking to obtain your first property and you are looking for a lender who can help someone in your situation.
Stay persistent and never give up, because if you do, what is the alternative...
Good luck and reach out if you have any questions. You got this!
