This is a business method, not personal finance... 

CF being "creative" goes to circumstances and the problem needing to be solved, it involves the application of techniques, assets, knowledge and methods that leads to a  successful conclusion.

That's the most efficient method. 

And well a little deeper into what I really have on mind/my plan is to hopefully find a owner occupied multi-family to live in until I can refinance to a regular conventional loan to than be able to get a new owner occupied property with a new FHA loan.I guess what I really want to find is a cheap/low purchase price property that is in less than in perfect conditions that has the potential to get me a good after repair value to create some equity on the property right after the repairs, preferably a multi-family, but if the numbers are good I could do a residential, I want to do this using a FHA or 203k FHA loan.I am trying to find a way to do this and the best methods.

BRRRR method all the way! 

This method is called "bid shopping" and is illegal in public work bidding, but your house is not a public work project so you can utilize this method.

I'd also appreciate hearing any stories about how you found good deals... such as the percentage they were below market value and the method you used to find them (i.e. through a connection, from MLS, "driving for dollars", direct mailing...). 

I could be wrong, but I also believe all payment methods listed in your original post are reversible.

Has anyone found any better methods to prevent storage in the hallways?

@Steve Mccullough your method of rehabbing distressed properties and offering fair, clean housing is admirable and definitely a goal of mine!
