Summoning @lordnigel to have a look at your musings here, this is relevant to his last post about passive incomes and the two different rulesets that exist depending on which side of the coin you're on.

There are some smart people snapping up industrial land on the fringes of suburbia (about 15-20km from where my house is) - in anticipation of the urban sprawl that will develop - close(r) to the freeway, and close(ish) to railway corridors.

They're going to make a fucking mint if the sprawl makes the rural change to suburban, - but, they're still going to make a mint, because the rural will need the industrial regardless.
