I somewhat doubt your assumptions about what homeowners think. The busybodies I observe definitely and loudly put their own needs first, but they predict the opposite effect of rental units from you - lower property values. Therefore, they would probably welcome outlawing investment properties, just as you desire. This dislike of renters seems mixed up with class or race consciousness. I think it's pretty widespread. I don't think it's possible to avoid the fact that people who can purchase a home are generally more privileged than renters, and so being against investment properties is not a simple matter of social justice.
