Interest Rates matter

Interest rates matter.  using on of those free online mortgage calculators I calculated the mortgage Payment for a $165,000 home at four different interest rates. The payments only include principal and interest.

At 7% interest $1097.75
At 6% Interest $989.26
At 5% Interest $885.76
At 4.85% Interest $870.69

I don't write much about mortgage rates because when I do I get so much spam it is unbelievable. I have to zap the spammy comments with my blackberry all day long. What is up with that any way?
