What can I do until I get enough money to invest?

[Abigail Rose Grant]

I really want to get involved in REI, but don't have enough money yet. From what I've read, I should at least have enough for a 20% down payment, so I'm saving up for that. But what can I do in the meantime? I'm searching for a mentor right now and reading anything I can. I'm looking to get involved in rental properties and/or flipping houses in the Baltimore area.
