1 bldg, same size apts, diff. maintenance - why?

Higher-floor apartments may have more shares.

aly has it right - if you look at the prospectus, you'll probably see that the number of shares for the same line increases by floor.

sorry " Maly" has it right.

<-- wonders why property taxes do not work like this

gcondo - well, they sort of do, in a coop, as the number of shares go up, the share of the building's property taxes go up. In a condo, property taxes based on price, which, usually, also goes up by floor.

In a coop, yes. In a condo, the city apportions tax, usually, by PCI - which does not take into account floor number.

In a condo the taxes may and quite often does take into account floor and view.

E.g., http://streeteasy.com/nyc/building/infinity-flats

Eight full-floor units. #2 and #9 have highest PCI due to terrace and roof deck. The PCI for #3-#8 increments a bit per floor.

Then there's the Apthorp, where PCI is purely a function of size. That's the more usual case.

my PCI is the same as every unit in my line, so my taxes are as well.
