Welcome Charles, I bet a lot of people on here wished they'd started thinking about investing and real estate while they were still in school, so nice work!
Depending on your goals, my initial reaction is to just tell you to get a good paying job out of school.
If you're looking to buy properties four units and under, most banks are going to want the loan/purchase to be in your personal name. If you're partnering with buddies, you'd buy the house in one person's name and then do a process called a "quitclaim" deed to transfer the property into your corporation. There are pros and cons and legal ramifications involved that you'll learn about down the road. When purchasing in your own name, having a good credit score and a good W2 income are going to be your two biggest factors in becoming financeable.
If you're buying over five units, you'll need a commercial loan. For these, the banks look a lot more at the asset rather than the person. With a single family mortgage, the bank wants to see that your income will cover the payments. With a commercial loan, the bank wants to see that the property, on its own, can cover somewhere around 1.3 times the loan payments. So while they'll still want you to be a financially responsible person, they're looking more at the deal itself.
I think a good next step (if you haven't do so already) is to start researching personal credit scores—what factors to take into account and how to improve your score. For many young people, just establishing credit in the first place is a hurdle for them.
Are you at GU Law? I live 5 minutes from there and would be happy to meet up for coffee sometime. I own a couple of properties and am a little further down the path than you. I would be open to sharing my own story about building credit, getting lines of credit from a bank, and purchasing and rehabbing properties.
Best of luck!
