Being in the properties business close to philadelphia,
500k in the suburbs can get you a fairly nice 3-5 bedroom home with a moderate yard.
In the city or on the mainline though, prices are much higher....they start at $500k and go up.
Its REALLLLLY dependant on where and how you want to live.
Jobs are good for that sort of thing, but your tied to living near a city in that case.
