If you plan to live in it then it's not really an investment property, it's a PPOR. Though most people view their PPOR as an investment, unless you plan to live in it for only a short time, your PPOR is foremost a home. If you're buying a home, then buy where you want to live. If you're buying an investment, your decision should be based solely on yields and/or your belief in future capital gains. As you're planning on living in the property, yields are obviously irrelevant. So... capital gains. You list two suburbs you'd like to 'invest' in yet you don't see much prospect for capital gains compared with other areas. I fail to see how this is an investment at all.
I wouldn't consider either Richmond or Abbotsford east, especially the latter, but that's unimportant. What's important is that you choose an investment which will maximise your returns. If you believe the outer suburbs are a better bet, then buy in the outer suburbs.
As Zed pointed out, you haven't even stated a price range or a property type. You should be posing questions to yourself rather than forumites.
