If we're talking about home prices why are you talking about apartments? There are a lot of costs associated with apartment buildings that simply don't exist for SFH and MFH builds.

This was an explicit goal of the designers of the early building code split: make single family homes as cheap as possible, and apartments as expensive as possible.
