Ran across this graph at creditdonkey.com. I'm sure various sites will have slightly different average rates, but this matches what I remember from late 1982 when purchasing our current house. 30 year fixed rates were running about 15% or more in our area.

I remember all too well. I bought a house in 1977 and had a 7% mortgage.
Three years later mortgages were running 10%-12%. Insane.
