Bingo!fuji said:If home prices are too high renting will win. If the rental market is too tight then owning will win.
It's not as clear cut as "where did the money you paid for rent go" because if you pay LESS for rent than you would have paid for a mortage you are saving the difference. If the savings add up to more than the home appreciation then it's a big win.
Plus, don't forget the added overhead of home owners insurance, HOA fees, property taxes and other misc. taxes.
To me, it is a simple thing - if the mortgage is significantly higher than current rent, save the difference and invest.
We call these folks "Fucked Borrowers" in the US because they follow the herd, buy homes hoping for appreciation and take on mortgages that put a stress on their personal finances (and lives!) .... all because they've bought into the myth that renting is more expensive. That is not the case all the time as you pointed out.
