Advice1: get a BS/BA in Accounting. Get a full-time job, save enough for a down payment. Get a loan. I don't think you would get a high enough LTV with a part-time job.
Or if you want to skip out of the full-time job scenario;
Advice2: Find a property for $15K with a min. repairs that will bring the ARV to $50K+
Find a hard money lender which is usually 65%-75%, let's say 65%.
With your $10K as part of the 35% skin in the game.
You can borrow close to $28500 before points and interest. You got closing cost to consider and property taxes to consider.
Best case scenario: You sell the house in 2 weeks priced at $50K minus ~$35K of hardmoney leaving you $15K minus $10K of investment
gain $5K and get taxed on that
Advice3: if you have a friends/family that can loan you private money

I think you should go with advice 1 or 3.
Biggest mistake is NOT "not starting early."
The biggest mistake is not planning 15 steps ahead of the game.
If you do not like accounting, why bother getting a degree in it? Forcing yourself to learn accounting is not fun unless you know what you want to do with it.
