Here is an old spreadsheet I did with distances from the CBD. I did some colour codes to see banding.
Rocklea is on the 10k fringe. About $250-$300k would find value. Anything less than $250k check the floodmaps. (on the BCC website).
Slated for CG but will have the flood hangover for a few years yet. Check insurance quotes as part of your DD.
Big bunnings and industrial area but low vacancy rates and close to good train and bus services.
Cheaper than Moorooka and Salisbury and I think that both (esp Moorooka) have priced out many buyers (PPOR & IP) who might consider Rocklea now.
Cheers
You'd be brave to consider rocklea.
