I would suggest looking into South Jersey where your money,especially 6 BR, will go alot further. Look into Gloucester and Camden Counties NJ. Delaware might also work-New Castle County.
Renting a 6 BR in some of the nicer Pa burbs is going to start $3500 and go way up depending on location.
Heres a good rental real estate site. Choose a county. Click all cities,private listings, and put in your criteria, 6 BR for example.
Good luck
