Hi KY
I have lived in the general Croydon area since 1981.
In that time, I have had a few businesses, been on the local Council (Lilydale), the Children have all gone to school here, made friends here, worked here.
We have had six different homes since first moving here, and most of our investment properties are in the Croydon catchment area ie between Chirnside Park and Ringwood.
As a business person here, I certainly got to meet lots of people. One of my businesses was a retail store in the Main Street which I owned and operated for five years.
This area has been good to us and good for us. It is quite beautiful, with lovely views of the Dandenong Ranges, mature street trees, and many of the shabby areas have undergone major transformation over the past twenty years.
Public transport, the Maroondah Hospital, the Government and Private schools, and if you need it, good access to the CBD, to the bayside beaches or to the Yarra Valley and on to the high country and the snow fields.
The Yarra Valley has much going for it, and Croydon is on the cusp between the built up metropolitan area and the valley.
In my personal experience, values have been steady - we got our rates notices today, and for example my first investment property, which I bought in 1994 for $105,000 is valued by the Council at $345,000. Not world shattering, but this is an 11 square brick veneer, mission brown, still with a single bowl sink in the kitchen and a rather ugly bathroom. It rents for $255 per week but a rent review is due in October and I would expect between $280 - $310 per week after that.
So not sure what your question really is, whether you are moving here or investing here and will be an absentee landlord, but we have found the area very satisfactory over the past 28 years so I guess that's a fairly good trial period for any area.
Hope this helps
Cheers
Kristine
