At closing they signed an additional 1pg standard rent back form our real estate agent had. 

They sarted last week and inspector signed of today.

So, I doubt they would sign off on giving you a loan so you can use it for more marketing to get more wholesale leads. 

Then after talking to them and getting a better sense of their plight, I caved and signed a 6 month lease and sent the other qualified tenants away.

You can check out some of them using the Network tab at the top of the screen here and selecting Events.

When I make a deal with a seller and the seller agrees to sign the contract and I hand over X amount of earnest money.

Where do I sign?

Already have a lease printed out that, should the renter sign, has a clause in there that says we're not liable for anything missing from the site.

This way he can’t just come back with oh it cost a little more than i thought Anything you sign I would write in that the signature ONLY verifies hours.

However, if the vendor is still personally on title as a tenant-in-common, there may not be a mortgage registered ... in which case, a conventional lender may not see the property at all ... or will simply see a property you own jointly with a another party.That said, you will still be signing an agreement with the conventional lender in which you state that you have disclosed all such debt obligations :-)
