@Lewis Jerico : some very good specific advice on this thread already. I'll give you some high-level, strategic advice.
You need to take inventory of the resources of you do have as well as the ones that you don't and find strategies that maximizes the utilization of your resources.
You have already identified that you are low on a few critical resources: cash, experience, network and education.
Resources that most young people do have are: Time, energy, and cognitive capacity (you can adapt and learn.) In the most general terms, we refer to this as "hustle."
So: trade time/energy/capacity for education. That's easy. read books, listen to podcasts, read forums, etc. Likewise, those resources are easily converted into a network: attend REIAs, meet with other REI's, find partners, etc.
To get experience, leverage the resources you already have as well as your new resources (education and network), to find a way to add value to an existing endeavors: volunteer to bird-dog, underwrite, property-walk, drive-for-dollars, fix things, etc for others.
Then the harder part: cash. By this point, you should have enough education to know what strategies are available to you. House-hacking with an FHA loan is a good way to get "cash" in the sense that you're leveraging the gov't to fund your "deal." Likewise, seller financing is another possible strategy. Wholesaling is another strategy that requires very little cash (which I'm not at all familiar with myself, so ping others who are.) Flipping is yet another strategy in which you can leverage your resources.
In short, the field is a lot easier if you have cash, but if you don't have cash, you'll need to leverage your "hustle" a lot more. Don't discount the value of hustle. It counts for a lot in this business!
Hope that helps!
