Recent news affecting co-op / condo buyers, sellers, boards and residents. This week, Mayor Bloomberg proposes a residential smoking ban. Or does he? Plus, a tree may grow in Brooklyn but a co-op's just sprouted in the ever-burgeoning Bronx; the highest-priced New York City co-op ever gets sold; and what could be the second-priciest condo gets put on the market. Good thing Co-op City is staying affordable. And we wonder what Jennifer Aniston's combined co-op apartments will sell for now that she's moving (or moving in) elsewhere.
