Despite the tribulations of the housing market itself, the number one real estate site in the country - Zillow - is thriving. 

CEO Jeremy Wacksman sat down with The New York Times to discuss what may be causing the dip in the housing market and what keeps Zillow afloat amidst it all.

The Seattle resident was appointed as CEO a year ago, but has been with the company since 2009.

Wacksman added that the major issue with homebuying in the United States is that there is an availability problem. 

'We have an affordability crisis, which is driven by an availability crisis. It is a supply-side problem,' he said.
