We still have 100% financing options available for those counties. All qualify for the USDA loan program. Right now, though, as a result of the government shut down, as well as the great demand for this product, the USDA is backlogged (in NJ, and likely PA too) to September "packages". These loans have already cleared through the mortgage company's underwriting, and are stacked at the USDA offices awaiting review and hoped for approval.
If you contact me and I'll refer you to several good loan originators. Chose the one with whom you feel most comfortable. Compare fees. They will determine if you qualify and guide you through the process.
I'm happy to help you with your real estate selection too -- you are covering quite a large target area with the counties you've listed. Perhaps I can help you determine which area best suits your needs. That might make the best starting point.
