@Hilary Stalder thank you for being so candid. I know it's not easy to put it all out there.
Student loans are a pain, and lots of people are in a similar situation as you. The good news is that there are lots of loan mod options available, so I would look into income-based repayment and other, similar options, first.
Deleverage vs. invest is a difficult question. Big companies even have this issue, and their solution is something that you may want to consider.
Find a capital partner.
You have something that many aspiring real estate investors lack - track record and experience.
With the right capital partner, you can stretch $20k to $200k in equity. That would allow you to buy a $1 million property, which comes with a lot of benefits.
Get a copy of Raising Private Capital by Matt Faircloth from the BP library. It will completely change your perspective on real estate investing. This strategy will also send you down the path to financial independence if you play it right.
