Public transport

I only pay about $11 in transport costs each day, which is cheap for us. It does mean a very, very long commute.
It's not relevant to this discussion, but house prices where I live are almost the most expensive in the world - we're living as close to our jobs as we could afford to, and while my partner can change jobs for a closer one if he can find one, I would be insane to (my job is understanding on leave for children, mental health (I have PTSD), emergencies, bushfires etc and has excellent superannuation).
Our house cost $320K and is falling down and was full of asbestos - it required restumping, rewiring, replumbing, and has nearly no internal walls. A fairly old house purchased by a friend of mine in cycling distance to his work (about 15kms) was $750K, and needed quite a lot of repair work. The international norm for an average house price is three times your yearly income - in Australia, it's vastly more.
Rental is very threatening in Melbourne for people with children, and I and most people I know have experienced suddenly becoming homeless due to agents raising rent outside our ability to pay, and finding it hard to find a place to move into that will accept children or pets, or not be more than two hours away from our jobs.
The national national median
house price of
AU$539,400 (
US$489,538) means that our house was very, very cheap, which explains why it's so far away and so damaged.
And now I've rambled on and deflected away from the topic - which is tiny living! And speaking of that, here's a Seattle nail-house which is kind of funny:
