At the same time, two census tracts that cover parts of the catchment each lost more than 500 units of affordable housing from 2000 to 2014, according to an analysis published by the Federal Reserve. The median income in the area of the Arvilla increased 26 percent from 2006 to 2016. And as for home prices? They doubled in University City from 1998 to 2011 — but in the catchment, they tripled, adding a cool $100,000 or more to a property's price tag. For instance, a 1,500-square-foot house on the same block as the Arvilla recently sold for $540,000.
