it seems to me there are several kinds of risks in a mortgage

1) Payment risk

2) Inflation risk

3) Return Risk.

Now the Feds sell 30 year bonds, which price the Inflation risk and Risk free return for bonds.

so 30 year mortgages can be priced against 30 year bonds with a small premium for Payment risks.

i would rather see the tax deduction go away then the 30 year mortgage
