Currently I'm reading any book on the subject I can get my hands on, I listen to the bigger pockets podcast when I'm not reading and I frequent these forums quite regularly.

Or can I just sign a regular purchase contract with the seller, and then an assignment contract with the buyer, and a subject to purchase agreement with the seller and buyer?

There a few providers of such structures that post regularly to these forums.

KRAUS KPH-1630CH.I have installed a few other Kraus faucets and all have been commercial quality and look to be built to be used regularly

Other than the unleveraged real estate, do any of the other options provide regular cashflow?

I have been making regular payments on the loan. 

If you filed a Chapter 7 you had to pass the Means Test, which means you probably didn't have a 6 figure regular job, so being able to pay for repairs with high interest rate loans in a non-cash flowing property will be difficult.

A few common items to be on the lookout for:  Look everywhere inside and out for peeling or missing paint and fix as necessary, test windows to make sure they open, can stay open, close, and lock (old wood windows may have problems doing this regularly or be stuck all together), review basement for any signs of standard black, non-toxic mold/standing water, make sure all stairs are cleared of tenant items (no bikes, boxes, etc.).   

If the tenant owes missing rent or money for rental house damages, the landlord may ask the court to convert the case to a regular civil case.

A regular programmable thermostat will do the trick right?
