Carson, first congrats on the upcoming degree, I'm sure you'll have a solid baseline for property management based on your degree in facilities management.
What does your dad invest in? Real estate? Other assets or businesses?
What's your plan for when you graduate? Will you live at home to save money? Do you have a job lined up? Have you talked to property management companies about opportunities?
How you're thinking about things is on the right track - developing a network of mentors you can talk to is a good thing. Having a little money in the bank from a day job is a good thing. Building a credit history...all on point.
Things that I would also start looking at: where do you want to invest - locally, nationally, internationally? Can you evaluate whether something is a good investment - use the BP calculators, build your own spreadsheet, identify what seems like a good deal to you (everyone has different criteria). This analysis will actually help you determine how much cash you need for your first deal which will guide your decision for a well paying facilities job.
You're on the right track, just remember patience and diligence are a good thing.
