The Relationship Between Owner Occupancy Rate and Performance

[Wilson Pun]

While the general understanding is that a higher owner-occupancy rate in a market or neighborhood indicates that owners take better care of their property resulting in higher property value, better neighborhoods and higher rent, I'm wondering if anyone's seen otherwise.  

Namely since the owner-occupancy range is so great (30%-80%) in many large markets, is this OOR to Rent always an absolute direct correlation regardless of range or, for example, if owner occupancy is 80+, is there a retracement in rent or any other factors that would cause these areas to be less desirable to an investor?
