Look, in an ideal world, you are right. However, it seems with IP's there are 3 things: Growth, Yield and Risk - but as others before me have said, you only get to choose any 2.
e.g. You can get high CG and low risk but this comes with low(er) yield - such as a unit close to CBD. Or you can get high yield, low risk but also low CG property - such as you might find out in a small country town. Other investors choose high CG, high yield properties but these come with higher risk.
Of course there are always some exceptions that break the rule - but you tend to 'luck-out' on these if you ever end up with them.
RedCat has chosen the high CG, low risk path - and that suits her for where she is at right now. That's why there is no one way to do things that is right for everybody - as everyone has individual different needs and circumstances.
What's an example of high CG, high yield and high risk?
Can't we do high CG, high yield and low risk? Market arbitrage is bliss
