For me, the only "catch" is that there can be times (like now) when credit tightens and extracting equity becomes more challenging.
I plan to mitigate against this by extracting equity and every opportunity and parking it in an offset account for when I need it. Hopefully, that will help me ride out those times.
Naysayers will also point out that property values may stagnate or go backward, making equity extraction impossible. I will have a sufficient spread of properties in high growth areas that will mitigate against that risk too.
I also plan to develop other income streams to reduce my reliance on the LOE strategy. Of course if the LOE strategy works "like a bought one", then my additional income streams will be icing on the cake.
I'm also planning to buy some property (maybe even commercial) with my SMSF and look to using that to produce a tax free income form the time I'm 55.
If all of the above lets me down, then I'll find myself a park bench to call home and rely on my Somersoft friends for food parcels etc.
