Here's my question.  Are these same homeowners claiming the income they're getting from their relatives as these relatives are not being "given" free housing?  Only reason I ask is that I know of someone who has a total of 20 people in her house, most NOT relatives, and she's been collecting rents for years.  Is it so hard that the State can't cross reference the # of driver's licenses registered to one address and then check for NON reported rental income on State tax returns of the registered owner?  Is this really rocket science?  Theft right under your noses while you have the tools to catch it.
