your money will go farther in Edenton than Baltimore.

I'm not familiar with the Edenton area, but if you get farther away from the ocean in NC, prices will drop.
I live in Durham. Been in NC since 2000 and have lived in Chapel Hill (17 years), Raleigh (3 years) and in my new little house in Durham since Jan 6 2021. (Yes, I was moving in while the Capitol in DC was being attacked.) If you are concerned about health care resources, I would advise being closer to larger population centers. The Triangle area (Raleigh/Durham/Chapel Hill) is booming and prices have gone crazy. But if you get east or west of the Triangle by 30/60 minutes, prices will drop and you will still have access to excellent health care. If you go east--to some place like Wilson or Rocky Mount, prices drop even more (than Baltimore compared to Edenton) and you will be close to Greenville for health care. Amtrak stops at both Wilson and Rocky Mount, which makes it easy to get on the train and run up to visit the DC area.
Rocky Mount has been on some lists of best places to retire https://belmontlakepreserve.com/rocky-mount-nc/best-cities-to-retire-in-north-carolina/

It takes an hour and 20 minutes to drive from Rocky Mount to Edenton and just about an hour to drive the other direction to downtown Raleigh. From Rocky Mount (or Wilson) it's about 40-45 minutes to Greenville, which has University Medical/Dental/Nursing Schools in the UNC System, thus lots of health care resources available in the area. https://info.ecu.edu/health-sciences/
