it was a rhetorical question. If rents soar, and prices drop like a stone overnight, ofcourse affordability would increase. I was just pointing out the inherently flawed logic of the argument presented. It's a moot point anyway. On anything other than a short term basis if house prices fell like a stone rents would also decline, or in this case stay the same until yields are at reasonable levels, because yileds are currently very low.
