In areas where you can “build what you want” (eg semi rural or similar) there does seem to be a strong preference for SFH, followed by duplexes (though I rather call them 2x townhomes) followed by rowhouse-like things in 4 or 6 or more, followed by actual big condominium buildings. And based on pricing, it seems that most would pick the SFH if they could afford it. Of course, in a city with transit and traffic pressure the calculus may change. Where I am there’s basically NO redevelopment pressure, as you can find empty land within a mile.
