Portland, Maine historical house prices graph

The above chart estimates the market value of today's median-priced Portland, Maine metropolitan area house from 1983 until present. The red line represents inflation-adjusted house prices. The blue line represents nominal house prices.

Note: Some people try to assert that this is a graph for Portland, Oregon, as if I just copy everything Robert Shiller does. I chose which cities to track and I chose Portland, Maine. Notice below that the data source for this graph is the FHFA House Price Index, not the S&P/Case-Shiller Home Price Index. This is a graph for Portland, Maine, not Portland, Oregon.

Data sources and methodology

The chart on this page estimates the market value of today's median-priced house over time. The trailing nominal prices are derived by taking the recent median price of existing single-family homes, as reported by the National Association of Realtors, and discounting it by the FHFA House Price Index. The FHFA HPI is a "constant quality" index, so even though houses are built larger today than they were many years ago, this graph automatically adjusts for this variation. The trailing inflation-adjusted prices are then derived by adjusting the nominal prices by the CPI-U Research Series Using Current Methods. Prior to Q4 1977, the CPI - All Items Less Shelter is used.
