I can speak on Orange as that is where our latest property is.
For the price that you are are wanting to achieve perhaps look at South Orange boundered between the CBD, Peisley Street, Hill Street and the railway line but avoid the busier streets.
You can still purchase 3 bedders brick houses in that area but ensure that you do a building and pest report.
Also, with Orange, light and access to heating is important to them (for obvious reasons).
The new hospital in South Orange is now open, DPI are still looking at redeveloping their land to residential and Newcrest have an additional 40 years on their Cadia mine.
Good luck.
