There's a lot of costs involved with properly listing and marketing a property so having the agent justify why they charge their rate by showing a track record and a comprehensive marketing plan is a more valuable use of your time than haggling over half a percent.

There seems to be a list of "Real Properties Sold" on the OC website: http://ocgov.com/gov/pa/div/realproperty/auctions/...Does anyone know if this is comprehensive, or only a selection?

This is the point where the bundle of rights you have as the lessor/optioner of the property are so comprehensive and strong that in essence the ownership/control of the property has already transferred to you.The application of risk of loss passing is seen more in land contracts and lease to deed situations but given that option contracts can look very differently you'll want to pass it by your QI first.

If so, how accurate,comprehensive, and of course reliable, are they?

I have read about the ROBS strategy and my understanding, at a high-level overview, is you establish a C-Corp, a complimentary 401(k) plan, and your funds over to the new 401(k) plan where you use the funds for your company.

Zillow provides a good overview of the area. 

@Mike Easton I would recommend "THE SELF DIRECTED IRA HANDBOOK" by @Mat Sorensen, which is comprehensive guide for self-directed investors.

First and foremost, I’ve created a comprehensive checklist that outlines every task involved in a thorough cleaning. 

I found bigger pockets by doing a google search on "best real estate books", which resulted in a comprehensive list that I've recently used. 

At least that was the hope until the appraisal came back at $147K.To give a brief overview of the situation.
