The first thing that comes to mind is to talk to Habitat for Humanity. Their specialty is helping low-income people obtain ownership. www.miamihabitat.org/
Aside from that, you'll really want to reach out to local lenders and agents to find out what other offers are available for your market. I'd encourage you to ask them questions about the cost of owning a home. There are a lot more expenses on your back (like repairs) that renters normally don't incur. You'll really want to give some thought to how you'll handle those unexpected expenses.
