Well, you're setting up a series of chained hypotheticals. Regardless, in an apocalypse, all bets are out the window. I won't attempt to speculate.
Still, as per my other comment on this thread, the depopulation is gradual; 1.2 instead of 1.5 children due to infertility, and the death rate goes from say, 1,000 per 100,000 to 1,200 in 100,000. Given that, I don't think we will have a situation where people will trade a house for a sandwich.
