Try to sell public information "Delinquency Tax List" for 100s if not 1000s of dollars?

You'll want to drive all the streets of a neighborhood looking  for homes that have signs of vacancy (tall grass in the summer, or non-plowed driveways in winter), or are just in poor condition.Then look up the owner information via public records and try to make contact one way or another.

I don't think I'm much of a fan of having a profile visible to the public and my kids splashed all over it.

The state also posts public regulations.

Public or private utilities, occupancy rate, % of POHs, economic vacancy.

In this case, I'm fortunate, as this tenant is on 100% public assistance. 

Sometimes legislative bodies will write an initial draft of a bill with super harsh restrictions and then lessen the restrictions in response to public backlash and in an effort to pass a bill.
