How low can the mortgage rate go ?

Today, the average interest rate for a 30-year mortgage dropped to a record low of 4.71 percent. The average rate on a 15-year fixed-rate mortgage fell to a record low of 4.27 percent.

Why so low ? Because the US government is pumping  $1.25 trillion into mortgage-backed securities. But the money is set to run out next spring.

So what will happen to the mortgage rate and the housing market after next spring ?

I am thinking the 30-year mortgage rate may drop to below 4.00 percent next year some time. If so, where the SP should go then ?

The 10-YEAR TREASURY NOTE has been up for several days in the past few days, any hints on this ?

Is the deflation or inflation to come in the next few years ??

We need to think over these things, but these are pretty complex and difficult questions for sure.
