There is a lot of good advice here. I would also add that you need to spend some time determining what your niche is going to be.
Just because you can buy distressed property from a bank at a severely reduced price doesn't mean you should. Meaning, there may be a good reason why the property is bank owned. If you don't understand the market you could be setting yourself up to fail just like the previous owner.
My suggestion would be to spend some time getting to know what is going on in your market. As suggested, a mentor may be your biggest asset here since the commercial sector property spans so many different types properties. Once you understand the short-term needs of the local market, you can then start planning the next step.
Since you are looking to fix-n-flip, you are "probably" going to find the largest pool of buyers in multi-family projects. Perhaps you could look at buying failed condos and converting them back to apartments? Even in multi-family scenarios, you need to understand the market in order to ensure you are providing a desirable end-product (not only for the renters, but buyers too).
Example, it doesn't make sense to convert condos to high-end apartments if there is already a lot of existing inventory available when real the need is for Section 8 units. Nor would you be best served by buying those condos and converting them to Section 8 units.
I guess I should mention you also need to address your capabilities. If there is a need for extended stay hotels, I don't know as I go and look to convert a failed Best Western. The financial needs of a project like that may be a prohibiting factor right now, but my point is you need to know your limitations and not take on something where you get in over your head. That might eliminate projects like strip malls for now.
You also made a comment about bank financing. I don't know as I'd plan on bank financing for a non-performing asset. If it isn't performing, it won't debt service so there is little chance of financing. Unless, you were talking about the bank who is selling the property carrying paper on the property until you sell it. That "can" happen, but I wouldn't expect it to.
In my experience, these types of transactions are done with cash, not financing.
