There are indications that Treasury Dept is considering a plan that, if true, would use Freddie Mac and Fannie Mae to "force banks" to make mortgages available at 4.5% for home buyers. The low interest rate would be available only to those who are purchasing a home, and not for refinancing.
To encourage banks to issue new mortgage loans at lower rates, the Feds are offering to Mortgage Backed Securities (MBSs) at a price equivalent to the 4.5% rate. The details of the Fed's MBS purchase plan are not known at this time. However, one possibility is for the Treasury to raise money by issuing bonds at 3% interest. This would allow the government to turn a profit because it would be buying MBSs that pay 4.5%.
Senior Treasury officials said they were optimistic that subsidizing lower mortgage rates with taxpayer dollars would help revive the housing market. In a meeting with the National Association of Realtors last month, Treasury officials said that the plan will be a more effective way to help homeowners than focusing efforts solely on borrowers who are struggling to meet their monthly payments.
Historically, interesting things happen when the gov tries to create artifical floors and ceilings (ceilings in the case)...we'll see how it works out, but I'm telling my clients that 5.25 is a great historical rate...if you get greedy and look for 4.75%, you are passing up a sure deal at 5.25.
