New Markets; Philly and Chester County, PA

I have been investing in the north and central New Jersey area for the past 3 years. Lately, the market for SFR has become saturated; properties are overpriced and few and far between. I have been looking to expand into the Philly and Chester County, PA area. I have been establishing relationships with a network of realtors, contractors and investors. I don't plan on completely taking my business to a new state, but I would like to utilize my current network and resources that I do have to keep my options open. The goal here is to expand by first reaching out to fellow investors on BP forum. Next would be to establish some boots on the ground in this area (i.e. realtors, contractors, other investors) Anyone have any feedback on the temperature of the investment market in the Philly area and surrounding counties. Has anyone been looking to expand in other markets other than your surrounding neighborhoods due to growing competition?

Any feedback would be great!
