Priced well? Or is the maintance too high for a 1million dollar price tag...

Maintenance is a bit high, and prices correspondingly lower, because the co-op carries a hefty underlying mortgage.

It used to lease the land, but bought it in 2004, taking out the mortgage to do so.

How big is the mortgage?

$13,500,000, $12,000,000 of which was for the land.

It is my understanding that the commercial space is independently owned.

Worth it at 900k ?

Don't know. There're lots of Third Avenue 1960s buildings that went co-op in the early 1980s. Pick a few and run their numbers. They might even out, roughly.

On ACRIS there's a 1980s 50-year lease of the commercial space to the sponsor. Don't know what the story is now, but the co-op does own the commercial space.

You'd think that the broker for a place with unusual numbers would have the financials ready at the get-go, to answer the obvious questions.
