Most dogs in this category do have formal training and documentation, but proof of this is not required.

No formal training. 

Seller is not experienced in the process and did not hire an agent for representation.I sent in a formal contract offer. 

I assume this would require some sort of formal parcel/lot split with the city if it were allowed, anything else that would need to happen?

Lay it all out together then go see an attorney to formalize. 

Is it mostly formal written communication?

I still got an inspection done though, just to know what problems I had to formally address - can't let the sell fall through at the flip.I don't think that I'd remove it for most deals though, so my example is the exception to the rule. 

The solo 401k plan participant may withdraw at any time (after completing a distribution form), all or any portion of her account balance attributable to “rollover contributions” and/or “after-tax contributions.”Employer Contributions: Employer contributions are subject to more stringent distribution rules and may be distributed upon the solo 401k participant’s severance from employment, death, or disability.

I’ve got a general idea of my plan, which I’m drafting formally on my desktop.

If you come to an agreement with the seller, you can say that you'll have the formal contract prepared in a couple of days for the seller.
