Are you talking about married couples taking different bedrooms in one apartment? Or single individuals (not living as couples) taking different bedrooms in one apartment?

Yes, we do a lot of roommate shares here in the US; I lived in about 7 of them through my 20's. But I didn't live with my wife in a room share. I'm now married and I live with my wife, and we are effectively rent-sharers now.

It's still not enough to have a 20% cash savings rate, much of what would be saved as cash instead pays debt (mostly college debt + debt originating from emergencies/unemployment). But we almost certainly couldn't afford a local property of any type, save a studio apartment on the outskirts of the city, with a 20% savings rate over the next 5 years. And part of this has to do with down-payment financing arrangements nearly always losing out to deals paid in cash on-the-spot. (Indeed, there are people roaming the streets with certified checks from $800,000 - $2,000,000 who are viewing new-to-market properties daily)

I've seen both (OK, they were not married, but in a commited relationship), where of course the latter case is more common.
