You sound a bit frantic in your question, so perhaps the best response is to your question is "what is your situation?".
There are programs currently available for financing, but if you have a poor credit score perhaps you are focusing on the wrong step. Perhaps you could find the least expensive housing solution first, then think about how to clean up that credit score.
This country has been running on credit for so long that we aren't thinking clearly anymore. Take your $6000 and make sure that all of your outstanding debt is paid off, then slowing begin to save for a home as you are repairing your credit. You will have a sense of calmness if you can build that nest egg into a sizeable down payment while maintaining debt free living.
Go ahead, it may sound scary but you will be amazed how good you will feel about your future. Good luck!
