Are you sure they actually leased out at that amount but not referring to the asking price? because generally they are all negotiable...
And when you look at Rhodes....... oh dear Rhodes................
I've had friends that bought Rhodes OTP vacant for a month...they need to reduce their rent to meet the current 2nd hand unit rent to get tenants.... and my other friend even offer 1 week free rent...... all bought in Rhodes/Wentworth Point.......
Agree @ wentworth point and Rhodes is Very bad. But that's due to over supply in that area. It depend on the area. For example in Westmead the vacancy rate is 1.6%.
Also with Rhodes, and Wentworth point, these suburb are still fairly new. so the old established one is generally around 5-15 years old, and they're roughly have the same function and feel like the new one (i.e. 2 bed 2 bath, with lift, and secure car space).
Where if you look at some more established suburb (i.e. Lane cove, or Westmead). the old unit can be up too 40-50 years old and they're completely feel different to the newly build units. Generally they're like 2 bed and 1 bath with 1 unsecure carspace.
For example: this 1 bed units is already leased for 570
