The substate areas of Southern New Jersey and Suburban Pennsylvania experienced healthy rent conditions, showing overall rent growth in the suburbs of 1.9% over the year with average effective rents at $1,442. However, rents in Center City showed a lackluster performance, with a decrease of .6% since last year at this time. Rent growth in Suburban Pennsylvania was 1.5% since mid-year 2012, while Southern New Jersey rents grew by 2.8% over the same period. Effective rents across the entire Philadelphia metro area grew by 1.2% over the past year.

For the metro as a whole, average effective rental rates are $1,642 ($1.63 per SF). Center City effective rents average $2,180 ($2.21 per SF) vs. $1,442 ($1.42 per SF) in the suburbs.

Limited supply in recent quarters has led to healthy rent growth and low vacancy in the Center City Philadelphia. Despite this healthy performance, the number of units under construction is significant, and as a result, Delta projects that the 36 month supply will slightly exceed the number of units that will be absorbed in the Center City area by the end of their 36-month forecast period. There are currently about 2,500 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,
