I finally found my source on nationwide median home prices, at least going back to 1968. Apparently the NAR only started keeping track of this data in 1968, and so it is probably utterly impossible to find median existing home prices from before 68.
This is a graph of home prices divided by median family incomes, which should be useful as presumably home prices are based on how much money people actually make and can therefore afford to spend, not on inflation or other such things. Note that there is a difference between "family income" and "household income", and that family income tends to be about 20% higher than household income. This is because "household income" as a statistic includes households with only 1 person, while families tend to consist of couples, with both people often working.

While the home price/income ratio seems to have reverted to the norm, this doesn't actually mean that prices have bottomed. There is no reason why prices can't well overshoot the bottom. And, note that I have estimated today's median home price at $180,000. If you want to assume it's lower, you'll get an even lower ratio for the end point of the graph.
