The government is in a great position to cut rates by about a point: Through Fannie Mae, Freddie Mac and the Federal Housing Administration, it now controls nearly 90 percent of all mortgage originations. These lower rates would apply to most home buyers who take out a loan under $729,750 for a house that they will live in.

Along with lower rates, the government should provide temporary down-payment assistance for buyers. The government could, for example, match the amount of money that buyers use for a down payment, up to $15,000. Because the government now controls the bulk of all mortgage financing, this money could be provided directly at closing. Homeowners who refinance their current mortgages could also receive assistance, allowing them to avoid foreclosure.

Programs like these would draw buyers into the housing market and reduce the backlog of unsold and vacant homes. Investors and speculators would be ineligible and would face the full cost of their mistakes.

By stabilizing house prices, these programs would benefit the bulk of Americans, who own a home but did not get involved in the subprime mortgage market. Price stability would more directly achieve the goals of the Wall Street bailout: increase the value of mortgage-backed securities (by increasing the value of the underlying houses) while injecting government capital into the financial system.

Some in Congress have suggested allowing homeowners to go to bankruptcy court to lower their mortgage payments. But this would only make credit more expensive by reducing the willingness of companies to lend money. It would also worsen the current problems by letting bankruptcy judges reduce mortgage balances — imposing even greater losses on the owners of the mortgages, whose problems are at the heart of the financial crisis. Such a program would also be limited to only the most indebted and, in some cases, financially irresponsible homeowners.
