Rental restrictions

I'm not the listing broker (and so I'd advise that you check with him/her) but often with these subsidized units, you're not allowed to turn around and sublet them because they're intended as a primary residence.

Huh?
Listing says "This apartment is a moderate-income unit, the buyer's household income cannot exceed $208,065 annually", which sounds rather high, considering that the minimum income to put somebody into the top 1% in NYC is around $550k, and nationally, the top 5% threshold is around $299k. Nice to know that *really* rich people can't buy them, I guess.
