Philadelphia City

An increase in supply over recent quarters has led to rent declines and rising vacancy in Philadelphia City. The number of units under construction has risen slightly, and as a result, we project that the 36-month supply will slightly exceed the number of units that will be absorbed in Center City by the end of our 36-month forecast period. This can already be seen by the rising vacancy rates in the last quarter. There are currently about 3,513 units under construction or planned that may deliver in the next 36 months in Center City Philadelphia. Philadelphia’s supply/demand relationship indicates that vacancy will continue to edge up slightly and rent growth is likely to stay negative over the next 24 months. This trend will be temporary, however, and we expect Center City to remain a healthy market.
