Where is all the affordable housing?

We're not there yet but it seem inevitable that one day soon people will be asking..."where is the affordable housing?"

New York city is losing affordable housing at an alarming rate and needs new laws to protect whats left according to Assembly Speaker Sheldon Silver. "if we do not act quickly to extend our rent laws millions of working New Yorkers could lose their homes."

Landlords sing a different tune...they are speaking about the increase in the cost of heating oil, insurance on the buildings (especially hi-rise bldgs), and increases in real estate taxes. Who, they ask, is going to make up these costs?

And so it goes...landords and tennants all in need of help from the state government. But what about new construction? No one is building apartments for low or middle income housing, there just is no profit in it. So, as more and more affordable units get more expensive there is very little time left until we hear the question....where is all the affordable housing?
