The same report shows the fastest growing rents are in "South Philadelphia West" (sounds like realtors are keen to shed the Southwest Philly moniker) and East Parkside, where rents are up more than 10 percent in the last quarter. But the most expensive neighborhoods in the city remain west of Broad (from Logan Square south through Rittenhouse Square and west through University City) and in Northern Liberties. Rents in University City and Logan Square are the priciest, at $1,800 monthly.
