Philly is my hometown, and I still have many relatives there. Our (extended) family keeps a condo in Rittenhouse Square. The Strawberry Mansion area should be a good opportunity for long-term goals. I'm glad to see that you intend to "sit on them for a while." Good intincts. The link below (I am not advocating that you use this real estate company, just their MLS feed) is a start for your search, but please do contact a good local REALTOR with residential investment experience. Best of luck and happy hunting!
