Seller Financing-Creating Wealth method

[George Smith]

Has anyone used the method used in the Creating Wealth by Robert G. Allen which uses a point system for determining potential deals? Everything seems pretty standard but seeing that this was written back in 1983 when rates were pretty high Im wondering how this method applies to today's market. 

Robert talks about listing a newspaper ad. Do enough people still read newspapers to get a response? Has anyone left ads on craigslist looking for a motivated seller? 

Thanks,

George
