Reach out to a local agent who can help you in your search
Trulia isn't very helpful these days as many agents stopped answering questions here, in the Q&A section.
The reason is - there are way too many glitches on this site - agents used to be notified when questions from their areas were posted...........sadly, this doesn't happen anymore.
Agents also used to be notified when new responses were added to a thread.............that's not happening anymore either.
Many questions (like yours) are asked, and wind up floating in internet space!
It's doubtful an agent from Philadelphia will see or respond to your question, so you'll have to be more proactive.....try using the search option to find local agents (top of the page - use gray arrow for drop down menu and select "agents")........IF that still works here - no way of knowing!
