I'm not worried about the bad news. Earlier this century, I was a buyer in some of Perth's worst suburbs, before they went up more than threefold. Most of the "junk" I bought for around $80,000 was sold for well over $300,000 in 2006/2007.
Because of the stigma, everybody overlooks the fact that dual occ sites in Frankston are selling for a song. I have bought several, mostly for under $300,000. You can easily buy a Frankston house on a largish 600sqm+ block and, when you are ready, put up another house up the back. Its pretty hard to find that sort of thing anywhere for these sorts of prices.
The Council is pro-development. And, truth be told, the crime rate in Frankston is pretty much the same as inner-city Melbourne.
Lets get one thing straight. I'm not saying Frankston is paradise! It may not suit many IP buyers who are chasing high-status properties or absurdly high yields.
And be aware that there are many issues relating to the quality of tenants, property managers etc in Frankston. Go in with your eyes wide open and be mindful of the many ferals who live in the area (they are slowly moving inland, which is another good sign).
All I am saying (and I don't want to go into too many details) is that Frankston is cheap and has worked very well for me.
