I wish I new how that article got to 80k for a house in 1955.. I couldn't find a link to trust "interactive visualisation" they're citing and Google didn't help me either.
I wasn't born then, so no personal experience and everything I could find pointed more towards 5-10k, i.e. this advertisement
That can't be right, it must already be an inflation-adjusted number. My parents bought their most recent house in ~1970 for $30K, and that was a bit above the median for the area.
