So let me get this straight, you think by the new rules, they are unfair because the rates haven't been there for years.  How to explain to borrowers:  interest rates are inflation plus a rate of return of 4, an inflation target is 2.  So the proper realistic interest rate for a mortgage rate is 6, and that is where we are going to eventually get, sooner then later.  Better for the homeowner to prepare for this eventuality.  Also, the price of a home is overvalued by say 300,000 on a million dollar home, what sense does it make to loan 700,000? People don't buy houses lenders buy houses.   Where is it seem right that at today's prices homes are 13 times household income, when it should be closer to 3 to 4 times income. I see these new rules as a safe guard to the taxpayer who backs the banks!
