It doesn't matter where money comes from, a down payment is a down payment.I've done them more than a few times, but orchestrating a real no money down with seller financed deal is rather complex, can't be learned in some book as each deal is different and is no place for a beginner to start, IMO.

Your part as the investor is to orchestrate these people and the property into a profitable venture.

I've been placing down offers for properties and I've been highly considering orchestrating a double-close for my first (two) properties given that I may very likely end up in a career position with less income and completely separate from the one I'm in now.

I end up in this situation often.Approach tenants/squatters/former owners friendly wayPut them on a SHORT-TERM WAY-BELOW-MARKET Lease (90 days 1/3 of market value) Gives you the opportunity to: 1)have rental application 2)Photograph the property condition 3)Record serial # of appliances furnace HW heater 4)Ask them what needs repair 5)Plan repairs/ remodel6)Orchestrate an orderly move out 7)Make sure they fully understand that they as Tenants are 100% responsible for any damage done in the term of their tenancy.

Well for me no major issues, just had to spend time on the phone with the detectives, the squatter and my lawn service guy Jack to orchestrate the squatters exit.

He was the orchestrator of this event and was an exceptional instructor on the mechanics of financial analysis and was very good at pulling all of the disparate subjects together.

Some will tack on an "involvement" percentage of the total service fee, if they have to personally show up to orchestrate the work. 

As @Brie Schmidt said Illinois is a state where closings are orchestrated by attorneys.  

Completely unaware of the non-renewal notice.Given the guy has mountains of garbage in the unit (never would have been allowed but he was an inherited tenant), and the guy can barely walk around due to a bad back from age/ his work, how would you orchestrate this?

Once you get YES I'd rent, then you meet at the house and say your business only allows you to rent their home if they orchestrate puttig a a rent to own buyer into their home, you'd keep the option fee as your profit and hook that renter up with the seller to manage, yoiu are out.
