Most plots of home prices use a linear y-axis. This leads to the often wrong conclusion that a more expensive neighborhood has greater appreciation.
If two houses were purchase at the same time with a 500K total cost, their combined appreciation would be the upper line. Starting with a higher initial investment returns a greater dollar return, but not a higher rate of return.
When you want to compare home price growth, the prices should be plotted on a log scale.
