I'm late-twenties/early-thirties. I'm probably just on the old side to still be perfectly happy to rent a room in a shared apartment. If I find myself in a long-term relationship then I imagine my priorities will change, but part of the reason I moved to London was because I thought it would be easier to meet romantic prospects.

I completely agree that property prices in London are insane, and that the political system is doing nothing to reign it in (quite the opposite, from my point of view).

But, from what I've experienced, if you don't want to buy your own property, then it's perfectly possible to live in London without earning crazy hedge fund money.
