Data about assessed property values. (More info)
Harris County is third most populous county in the US and comprises most of Houston. Appraisal data is available per county so you would have to go to them by country rather than city. Fort Bend county is another one that makes up Houston and Sugar Land - www.fbcad.org as an example.
For Austin it is the same thing - http://www.traviscad.org/
