Chris Lynch sounds like you're starting off right by jumping in the forums and asking questions. This site and (equally as important) the BP podcasts have been extremely educational for me.
I'm not too far ahead of you. I started the same way in the same situation and also knew that taking some kind of action was the most important thing to start building momentum.
I decided to go down the road of agent to help overcome a great recession credit score and a lack of start up capital. The lessons I've learned from taking the licensing class and the network I've started to build with the agency I joined are already moving me towards the goals I want to achieve (like was stated above, buy and hold "passive" income is my objective). The in-office email blasts of listings from fellow agents in the firm keeps me abreast of great investment property listings even before they hit the MLS.
A couple of cautionary notes about the agent track:
1) There is a significant startup cost associated with becoming a Realtor. In Virginia the total for pre-licensing classes, licensing exams, E&O insurance, Realtor association fees, etc. comes to roughly $2,000. A great investment, imo, and one I funded through a method not often mentioned; a loan against a whole life insurance policy I've held for a while. The balance is due whenever I have the means/inclination to repay it (although you will incur interest, so talk to your ins. agent).
2) Even if you plan to work in your off-time from your day job, it's still a full-time commitment. Nights, weekends, and other days off are mostly spent networking and trying to get off the ground.
In the end, I've set out a plan for myself and feel good about attaining it. I hope this was helpful and best of luck choosing the right path for you!
