They charge between 6.5% and 7.5%
I haven't found the perfect PM yet.
These days it doesn't matter who you use as long as they are proactive in collecting the rent and responsive when something goes wrong.
With this in mind, I'd probably go for Ray White in Blacktown. I had an incident and an insurance claim earlier in the year and the PM handled the case well.
They are also in a cental location so many people walk past their office
