At 20 years and a year away from graduation, I think you'll have some credit. Have you checked your credit file (free at annualcreditreport.com) or your credit score (also can get free through Credit Karma)?
Are you working now? Do you have any steady income? If not, why not? You can work and go to college at the same time. I may be jaded but I think college education is the biggest waste of money with few exceptions (engineering, medical, law) and I have a post graduate degree. If you're here, it means you're interested in becoming a real-estate investor. To get there, there are some great programs for first time buyers. You stated in your introductory post that you may be teaching, if you're going to be a teacher, there are some great programs, search for HUD GNND program.
Lastly, and to answer your question directly, I think you should be able to obtain a loan if your parents agree to be co-signers. After a year or so, if you have a steady job or if you turn the place into an investment property, you can refinance it into your name.
