That's all you technically need to have "consideration" and a valid contract.

I have done a lot of background research but due to the size of project I want to confirm with experienced people.

If the property needs to go through probate, then the "owner" technically doesn't have the authority to sell it so not sure I would be trying to wholesale it if I were you.

Technically that could trigger their "due on sale clause" but I have never once heard of a bank doing that.  

Unless you have a property manager, it's the landlord's job to verify all information and run background checks. 

I've had my current job for 2 1/2 yrs making 75K per year and have a clean background but before I had my current job I was unemployed for a while and ended up filing for bankruptcy causing my credit to take a huge nose dive (sub 500 range). my Question is: to avoid the credit requirement (I wouldn't be able to find a co-signer) would I be able to put an entire lease down as a security deposit and pay my rent as usual so long as my income qualified?

Ben Mcmahon,It might appear you overvalue the TECHNICAL side of real estate in a consumers mind.

Verify income as you normally would, run their background/credit and talk to their last two landlords. 

When you start getting into larger deals, they will also pull your background (not credit score or income). 

@Crystal SmithHi Crystal, technically I’m purchasing.
