IIRC we had a Republican in office from 1 Jan 1970 thru 20 Jan 1977 ...
Jimmy Carter was a republican??
Jimmah oversaw the worst of it.
From lender411.com:
U.S. mortgage rates are considered to be at an almost all time low. Back in the late 70s and well into the late 80s, it was not uncommon for someone to have a double-digit interest rate on their mortgage loan. In fact, back in December of 1980, interest rates averaged 21.50 percent on mortgage loans. Someone borrowing $200,000 on a 30-year loan term during that year would have a monthly payment of $3,589. With today’s interest rates, a $3,589 payment on a 30 year loan would mean that you have a $630,000 house.
