First I have to say props to you because at 19, I was not thinking about Real Estate at all. So you are already well ahead of a lot of people.
I understand you are in college and pay for your expenses. Don't worry, a lot of us have been there, enjoy these times. For now, you should continue to soak up all the knowledge you can, which sounds like you have begun doing so. Find a mentor. Someone who has success in RE within your area and see if you can spend some time on the weekends or in between classes for a few hours at a time. Work for free, don't ask for money until you can bring in some money. The experience you get will be worth much more than any dollar amount you receive early on. It is also very considerate for the opposing individual to take the time to mentor a 19 year old, so add value to his/her business and I am sure they will be happy to help you learn.
Develop some skills as far as conversational pieces when talking to investors and sellers. Go around in your area and pick out ugly homes. Look for unmaintained landscaping. Bad roofs, paint, cracked driveways, old fencing, debris around the house, old windows, etc. Knock of those doors when you feel confident with a pitch and strike up a conversation. Don't be a pushy salesman. Just act like they are your friend as if you are checking in on them, while throwing in some questions about them and the house. You have to be able to read the person, don't use scripts, you'll sounds like a robot. Know how to pivot in a convo quick depending on the person in front of you. Let them grow some comfort, so they can open up and if they are thinking about selling, they will tell you.
Now that you have a lead, find local investors and let them know you have an exclusive off market deal. I would get a NDA prepared and have them sign it to establish the working relationship. You want to make sure you can trust the investor so they won't go behind your back to the seller. Once you have the investor side going and they like the property, you can head back to the owner and let them know your update. Find out what price would make them happy and also find out other motivation factors. Such as, do they need the money fast? Do they need cash upfront to move? Do they have a lot of trash? If so, offer to leave their unwanted items behind, usually investors will take care of it. Makes the move easier for the buyer when they can leave all of that.
From there facilitate with the investor and try to put the deal together. At the end of the day, you just have to make both sides feel like they are getting what they want.
Make sure your investors are buying at prices which are 30%+ below ARV.
This is just a little something to plant in your mind and I hope it sparks some ideas.
Goodluck.
