Core 4 in less populated areas of the mid west

[Scott B.]

I am originally from a small town in the Midwest so am familiar with it. In order to find enough deals to scale a buy and hold real estate I would most likely need to explore surrounding towns, say 20-30 miles between. When establishing your core 4 ( agent / lender / contractor / mgmt co. ) how large of an area can they cover before their expertise becomes diluted? So 1 core 4 team for a small region or different core 4 teams for each town? Thanks in advance for your thoughts!
