How did you go about fostering casual relationships with tenants?

A survey today would likely identify a meaningful population of folks forced into renting property as they move to find work following job loss. 

OR WA and other prime spots around the country like Charleston SC  there is basically no reason to buy any property for just the sake of  owning it if it does not throw off meaningful positive cash flow. 

Is any of this related to investing in real estate, or do I like to ramble on, forever. tic nervI can't find a single meaningful and honest response to this that won't get me banned.

@Dave Foster - Thank you so much for a clear explanation!!
