Historical US Housing Data Availability Papers like Ng and Moench (2011) and Negro and Otrok (2007) use historical housing data to estimate latent variables that correspond to some "true" or "truer" measure of house prices or housing activity. I've put together a table of series one could use as inputs in such an exercise. However, as we can see in the table below, very little data is available before the mid-1970s. I would like to expand this list with U.S. historical data (free or to purchase) that help to characterize real and financial housing activity as far back as possible.  What other series am I missing?

Commercial real estate data is not ideal, particularly data that is contaminated with mine and oil and water well construction. Regional data is fine but national data is preferred.
I feel this barely qualifies as an answer, but doesn't Shiller have house prices data on his webpage? Currently here.

Specifically:


  Historical housing market data used in my book, Irrational Exuberance [Princeton University Press 2000, Broadway Books 2001, 2nd edition, 2005], showing home prices since 1890 are available for download and updated monthly: US Home Prices 1890-Present.


I don't have much experience with this data directly, and am only aware of it through  Khandani, Merton, Lo (2013) ("Refinancing Ratchet Effect"), where they use this and many other data sources to construct a (very long) housing dataset for their simulation analysis.

Details of Case Shiller Series Construction methodology (from the end-notes of the 2006 edition for chapter 2):


  Even though there were no regularly published home price indexes
  before the 1960s, some economists were constructing indexes of home
  prices that cover most of the years since 1890. We found home price
  indexes from 1890 to 1934 and from 1953 to the present that used in
  their construction some device to attempt to hold the quality of the
  home constant.
  
  The nominal home price index 1890–1934 is from Leo Grebler, David M.
  Blank, and Louis Winnick, Capital Formation in Residential Real
  Estate: Trends and Prospects (Princeton, N.J.: National Bureau of
  Economic Research and Princeton University Press, 1956). It is a
  repeated-measures index based on a survey of homeowners in twenty-two
  U.S. cities, who were asked to give the value of their home in 1934
  and the date and price of the purchase of that home. Since it is based
  on repeated measures of individual homes, the series is protected, in
  contrast to the simple median price, from any bias from changes in the
  mix of houses sold or of the increasing size and quality of newer
  homes. Its shortcoming is that it depends on memories of the surveyed
  homeowners for the earlier purchase price.
  
  The nominal home price index that we constructed for 1934–53 is a
  simple average over five cities of median home prices advertised in
  newspapers. The cities are Chicago, Los Angeles, New Orleans, New
  York, and Washington, D.C. My students collected the data from
  microfilmed newspapers at the Yale University library, collecting
  approximately thirty prices for each city and year, except that for
  the fifth city, Washington, D.C., 1934–48, data came from a median
  price series from E. M. Fisher, Urban Real Estate Markets:
  Characteristics and Financing (New York: National Bureau of Economic
  Research, 1951). The median series for 1934–53 does not make any
  attempt to correct for home quality change, as do the indexes we use
  for the other subperiods. Improvement in home size and quality gives
  median home price an upward bias, and this is why I avoided using
  median price outside the 1934–53 interval.
  
  The nominal home price index for 1953–75 is the home purchase
  component of the U.S. Consumer Price Index (CPI). The Bureau of Labor
  Statistics collected data on home prices for those years for homes
  that are held constant in age and square footage. In the 1980s they
  discontinued this index when they switched to a rental equivalence
  basis for housing in the CPI. They made this change to correct what
  was considered a conceptual flaw in the housing component of the CPI:
  the CPI is supposed to be a price of consumption goods and services,
  not of investment assets. For our purposes, however, the old home
  purchase component is acceptable. There are, however, some
  shortcomings in the home purchase component, notably that it is based
  only on homes with certain government-subsidized mortgages, and the
  procedure that the Bureau of Labor Statistics used to correct for
  changes in the ceiling on these mortgages was not optimal. See J. S.
  Greenlees, “An Empirical Evaluation of the CPI Home Purchase Index
  1973–8,” American Real Estate and Urban Economics Association Journal,
  Carnegie-Rochester Conference Series on Public Policy, 17 (1982):
  203–38.
  
  The nominal home price index for 1975–87 is the U.S. home price index
  published by the U.S. Office of Housing Enterprise Oversight (OFHEO),
  which is available on their Web site. It is a repeat sales index, and
  thus controls for quality change. The nominal home price index for
  1987–2004 is the repeat-sales U.S. home price index produced by Fiserv
  CSW, Inc., successor to Case Shiller Weiss, Inc.
  
  Since 1987, the CSW and the OFHEO series have shown very similar
  patterns through time, though the sharpness of the increase is
  slightly more pronounced in the CSW series, an observation we
  attribute to the fact that our series is based only on actual sales,
  while the OFHEO series also uses both actual sales and appraised
  values as if they were sales. Appraised values are somewhat sluggish
  to respond to new market conditions.
