On a whim I bought a little of block of flats there a few years ago with absolutely no research and sold it for a modest profit a year or so later. It was a bit of a headache, though I had an amazing PM. I found out some months after buying it that I had bought on the 'wrong side of town'. So all I can tell you is that Inverell, like all towns, has a wrong side and a right side.
It's not a bad town, though. It seems to draw people from outlying towns, so they're struggling - I'm thinking places like Tingha in particular. TC will know more about Inverell.
