What are my financing options for buying homes from wholesaler?

[Jorge Martin]

Let's say I have about $20,000-$30,000 saved up for a down payment on a home. I would like to buy rental property but since I have experience in building everything from the foundation up I'd like to get a deal on a rundown home from a wholesaler. What are my financing options? From what I've read an FHA would be a great deal to work out with the low down payment and interest rates, but the home would have to be in good shape right? Are there any programs that could help me out?

What are your thoughts and opinions on my situation? anything would help and just so you know I'm located in southern California.
