I think it is best to shop around for good Property Managers. My sister is one and she takes no carp from anyone and wins awards through the Ray White group for lowest rental arrears, etc.
She was told recently by a tradie that the work he had done was good enough for a rental property - she told him it wasn't and he had to re-do it to a high standard or he would not be paid.
Whining and whinging is good for you. If you don't get it off your chest, it will only build up and make you more cranky.
I feel like I am a cranky, whinging old bag and very much a half glass empty person this year and anyone reading much of what I post will probably think that too.
I am going to start 2012 grateful for what we have with my glass half full and put the building work behind us.
