Have a problem !

I'm a little shy at this I have found a home for my family it's a foreclosure and it's a HUD home. How do I deal with the real estate agent when I do not have good credit nor a down payment.
I just hope someone can point me in the right direction. I have been away from keeping up with Dean's website for awhile family situation that I had to take care of.
Any suggestions would be greatly appreciated very much.
Thanks so much reading this.
God bless !
