It is warren county that is at the Delaware Water Gap. Again, I would be happy to e-mail you listings from that area, you would need to contact me(click on my name for info)I also work closely with an agent who covers the PA side of the Gap in case you are interested in looking a little futher.
Are you familiar with Sussex County? There are different areas. Near water, Farm areas. Do you want to live near Dover? What is your price range? How big? How many bedrooms and baths? Are schools a consideration? Once you have answered these questions, I would suggest you contact a realtor that works in the area ( I can give you a good one if you need one. Not me, I work more in the New Castle County and Kent County area). Just email me and I will give you a few names to interview.
