Zero Down - Not Subprime Loans - Led to Mortgage Meltdown

From the WSJ:

The evidence from a huge national database containing millions of individual loans strongly suggests that the single most important factor is whether the homeowner has negative equity in a house -- that is, the balance of the mortgage is greater than the value of the house. This means that most government policies being discussed to remedy woes in the housing market are misdirected.

....focus on subprimes ignores the widely available industry facts (reported by the Mortgage Bankers Association) that 51% of all foreclosed homes had prime loans, not subprime, and that the foreclosure rate for prime loans grew by 488% compared to a growth rate of 200% for subprime foreclosures. (These percentages are based on the period since the steep ascent in foreclosures began -- the third quarter of 2006 -- during which more than 4.3 million homes went into foreclosure.)

A simple statistic can help make the point: although only 12% of homes had negative equity, they comprised 47% of all foreclosures.

The difference in policy implications is enormous: A significant reduction in foreclosures will happen when and only when housing prices stop falling and unemployment stops rising.

....stronger underwriting standards are needed -- especially a requirement for relatively high down payments. If substantial down payments had been required, the housing price bubble would certainly have been smaller, if it occurred at all, and the incidence of negative equity would have been much smaller even as home prices fell. A further beneficial regulation would be a strengthening, or at least clarifying at a national level, of the recourse that mortgage lenders have if a borrower defaults. Many defaults could be mitigated if homeowners with financial resources know they can't just walk away.
