I'm not convinced that waiting is the best strategy. In my case I'm a 26 year old developer in Perth. I bought my first 2x1 apartment 13 months ago in a nice area 7km from the city and have now paid it off to the point where if I were to rent it out, it would pay for itself.

Now all my savings still go into the loan (offset account), but they are essentially a deposit for my next property which I will be able to buy around 28-29 (2-3 years).
