My first mortgage was 8 1/2%, second - 12 3/4% which I refinanced later with a variable rate mortgage which was 1.6% over the current one year t-bill rate (Best darn mortgage I ever had!!!) After that it was a 6.6% mortgage which I paid off early when my standard deduction was larger than my interest+taxes deduction (yes, it was a very small mortgage by then).
I would like to see 4%, but not at the cost of an inflationary hike.
Mostly, I would like to see my savings, after taxes and inflation yield at least 2%. The current inflation rate is about 2.5%, so we are long way from that.
IMHO, the war on savers still continues, it's just not as brutal as it has been previously.
