If it's for the purpose of potentially engaging them to manage the property I would not be paying for the service. Alternatively, do the research yourself on the web, I often find this brings me to the same conclusion as the PM.

No, I've never had anyone leave because of an increase. I've had tenants negotiate before which is fine. In the current rental market the negotiation power is well and truly with the landlord.

I've often wondered about Parramatta but it has had a bit of negative press lately. I'd be very interested in your thoughts on Terry Riders recent report:

"I've just completed my list of the No Go Zones – the worst places to invest in property in Australia – and the Parramatta precinct is right at the top of the list: prices are still falling, the long-term growth record is poor, there's a high rate of home re-possessions, serious crime is rife and it's at the leading edge of social disadvantage. You just don't want to invest in these sorts of places."
