Philadelphia continues its reign as 16th most expensive city for renters, ahead of Portland, Oregon; Atlanta; Minneapolis, and Baltimore. One-bedroom units in Philly generally rent for about $1,500 monthly and two-bedroom units run approximately $1,700 each month.

Year over year, one-bedroom rent is up 7.1 percent in Philadelphia.

Apartment listing hub Zumper has mapped rents in neighborhoods around the city, with some standard findings (spoiler: Center City East and Logan Square continue to be the most expensive places for renters) but some surprising ones, too. Researchers found that South Philadelphia's Point Breeze and northwest neighborhood East Falls were among the fastest growing rental markets in the city — prices up more than 14 percent in spring.

Other key findings cite riverfront neighborhood rental rates at  $1,890 monthly, while neighborhoods like Fishtown, Washington Square West and Spring Garden were closer to the city's one-bedroom median. Millbrook and a neighborhood Zumper calls "McGuire" (which may actually be Fairhill) rounded out the least expensive neighborhoods on the list, both under $600 a month.
