My mom and dad bought a new house in Indiana in 1966 for $19,000. Other than normal maintenance nothing has been done to it over the ensuing 41 years. If mom sold it today she could easily get $100,000 for it.
My grandparents bought a house in Westchester County, NY, for $40,000 in 1964 or so. Unfortunately, they sold it in the 1970s, but today it's worth well over $10 million.
Heck, my parents bought a home in the western suburbs of Chicago for $12,000 in 1964. The house next door which is smaller and frame not brick just sold for $299,000.
