Not only is it harder to get a home loan today than it was during the height of the housing boom when lending standards went out the window, but it is also harder to get a loan today than it was before the boom, when mortgage underwriting was relatively conservative.

That is, according to a new report from the Urban Institute. How much harder? Researchers there claim that 4 million more loans would have been made between 2009 and 2013 if lenders had used the same standards as were used in 2001.
