The longest history I could find using FRED data is this: https://fred.stlouisfed.org/graph/?g=1BPi3. So median house price to family income rose from 2.9 to 4.3 between 1963 and 2003, based on the series https://fred.stlouisfed.org/series/MEFAINUSA646N and https://fred.stlouisfed.org/series/MSPUS.

Getting long historical series of economic data is often a challenge due to changes in definitions and sampling methodology over time. FRED has a bewildering array of both income and house price series, all with subtly different definitions, most with pretty short histories.
