There has been voluminous discussion in recent years about following and marketing to the high end of the demographic scale, especial the real estate market. It’s been the focus of much of the new housing development action of the past five years, especially in big U.S. coastal cities. The high end development market has been widely chronicled here and within my weekly Housing Notes newsletter.

For buyers in the super luxury housing market, owning multiple homes is less about a primary residence with a second home and more about owning “stops on the big circuit.”

And as the rich own a greater share of real estate, major cities like New York, Los Angeles and London are going through a kind of “resortification,” familiar to posh beach towns or ski resorts, as their populations become more seasonal.

For Manhattan, these birds are rare in February and squawking on all treetops (bad pun for super tall condo penthouses) at full capacity in June.

And no, I never liked that band.
