I haven't dug into how they average these numbers out, but Singapore is especially interesting because their housing market is closer to just NY, SF or LA than it is to the general average of the USA.

In that sense they're doing really well. Actually their system is the hybrid market/subsidized one I theorized about above.

That's why Singapore is only top on one ranking and absent in others while the US is consistently at the top of housing affordability in most rankings, probably because US is a lot bigger than just NY, LA and SF.
