Hi chrisc83,
Well done with the saving and investment so far! The problem is that very few here are qualified to give the financial advice you're after, which is regulated unlike property investment advice.
You need to consider your risk profile, your current investment yield / growth and your personal goals. You might be able to get a better return elsewhere, but this higher return is likely to come with an increased risk of capital loss. Read up on investing – google books on 'value investing' to give an alternative perspective to the one you'll get from property investment gurus (almost all promote growth investing strategies).
I sure do agree that a great way to increase your investments is to save and invest more. But don't forget to reward yourself too when you reach each of your goals.
Good luck,
F. [cowboy2]
