I would not be rushing to buy ex-housing commission houses because they still look like housing commission houses. This will slowly change as they are altered and look less "poor cousin". In nearby suburbs, there are whole streets with not a plant, not a tree, just a little house plonked in the middle of a (sometimes) big block.
That will change over time, and is already changing right now, but it does cut down the buyers (in my opinion).
If I had buckets of money, I would try to buy lots of these, because as land gets scarce, these streets WILL change and get more valuable. Trouble with buying in one of these streets now is that for quite a number of years, you may alter your own, but until the street changes, you have the best house in the worst street, not the best idea.
