I must say that I find 1960's houses really under valued...We moved to the area specifically because we wanted a 1960's townhouse (having previously owned a victorian terraced home north of the river) and they are plentiful here and roughly half the price of properties with similar square footage of an earlier period.
We love living in a 60's house, lots of natural light, large windows, room sizes that work and no annoying cornicing to catch dust.
