Question about the "100 house" rule

[Paul Kennedy]

Been reading J Scott's book about flipping, and came across the "100 house" rule. As a new investor looking to flip and look on the MLS for some houses, is asking a real estate agent to show me 100 house before I potentially buy something sub $100k really something agents are willing to do? If no, by "looking at 100 houses" (or even 50) before buying, how do you go about practically looking at 100 houses in your farm area?
