Best way to price off market homes and plan purchasing routine

[Greg Berzins]

I'm a newbe trying to break into real estate investing.  I am been looking at lots of properties with realtors, and a few off market that I found that may be good candidates.  My questions are best methods to figure fair, "as is" values on these off market properties (county real estate assessment data) and other such sources, keeping realtors out of it.  And secondly, what people and procedures do you need to close a deal without a realtor (title company, personal lawyer, etc.)   Any thoughts or opinions appreciated...
