If  you haven't fulfilled all loan obligations I would entertain "roommates" if it is condusive to your living arrangements. 

Simple as that.If you are funneling funds from a plan funded transaction into an arrangement elsewhere that benefits you, that would be in violation of the IRS rules and could result in very severe tax consequences for your plan.  

I arranged a time where the buyer can go walk through the property (I contacted the seller, the seller arranged with the tenant) and boom, the buyer wanted to pull the trigger at a price where I made $5k profit.

The seller is selling the property to get some money and so we make an arrangement that helps me out before I agree to purchase.  

My firm arranged $36 billion in financing last last year spread over almost 4,000 transactions with 210 different lenders.

Our arrangement is that I fund the entire deal and he provides the experience and the management of the project.

I'm sitting down with them tomorrow night to talk over the details and what the arrangement would look like.

They have agreed to a MTM arrangement.

"Scheme" as a noun refers to a plan or arrangement to attain something or put an idea in effect.

I ask applicants as I've found many have no problem telecommuting or arranging their schedule around repairs if needed, and some actually prefer it that way.
