Doesn't look like it:

[W]e have to remember that cheap and easy credit was supposed to solve or at least address the housing problem itself. It was supposed to make access to housing possible for borrowers who otherwise had trouble getting loans. … What we can say, first off, is that the tradeoff – of increased homeownership for financial innovation in housing finance – was not worth it. The tradeoff was not even close to worth it. As the graph [above] shows, there was very marginal increase in home ownership. Even if we arbitrarily choose the year of the lowest rate of ownership (1993), even though it is not the beginning of the housing bubble, and compare it with the peak (2004), we get a 7% rise in homeownership, which can hardly all be attributed to financial innovation itself – and by the time the bubble burst most of the gain was wiped out.
