With sweltering Philadelphia hosting the Democratic National Convention this week, we thought it would be a good time to look at the red-hot real estate market in the City of Brotherly Love.

We're not kidding: Housing prices have taken off. The median price for a single-family home has skyrocketed 21.7% from 2015, to its current $143,000, the Philadelphia Inquirer reported in May.

What can home buyers expect to purchase in one of America's oldest cities? Founded in 1682, Philly, with a population of 1.6 million, has a housing stock filled with historic gems updated with contemporary features such as chef's kitchens and large closets.

Plus, it's the place made famous by the " Rocky" movies, the home of the Liberty Bell, and the birthplace of the Philly cheesesteak. (Pat's or Geno's? We're not touching that one.)

From row houses to ritzy mansions, here are some of the must-see listings in Philadelphia right now.
