Realtor sends me 100s of SS

I have a realtor that sends me 100s of shortsales, preforeclosures, foreclosures, etc. from 3 different states and I simply don't know the best way to wholesale the properties once I get the banks approval of the ss.

I also have an owner/landlord who wants to sell me his house which already has tenants in the house and wants to stay and keep paying rent. I never expected so many leads only after 2 weeks of investing. I desparately need advice from some of you pros on the best exit strategies for someone like me with no cash.
You may have to explain it to me like a 2 year old since I am so green. Make that a 2 week old.
:D
