Need help for financing investments

[Lawrence Mangalindan]

This site is great!, the podcasts grew my desire to get into investing going towards financially independence.  Based on my extensive research, I've decided that I'm going to niche on rental properties in either Indiana, Tennessee, or Texas and my goal is to get at least 10-20 this year.  I'm a real estate broker also starting out, I get clients here and there but I don't have a job where I'm receiving regular paycheck and so far I've got a bruised credit around 580 due to student loan and a hospital bill and I've been clearing my other debts.  I really want to take action and I don't want my credit situation get in the way of financing so can you guys suggest what else can I do to set up my financing? I would truly appreciate it.  I'm also gonna pick up the "No/Low Money Down" book as well.  Thanks!
