In general, the Triangle area has seen annual appreciation of about 6% over the past 5 years. Because the appreciation has been slow and steady, prices have not overinflated and market adjustments are much less likely than in many other areas. The area continues to grow. Retirees move here because the weather is good, but prices are much lower than much of Florida. There are major universities and the Research Triangle Park, which draw students and professionals. This area has been called the "Silicon Valley of the East" - but home prices here are less than half of what a comparitive home sells for in the San Jose/San Francisco area. There are sports and cultural activities, and Raleigh is close to the mountains, the ocean, and many lakes and rivers. There's something for everyone!
If you are looking for information on that particular zip code, I'm sure a real estate agent will be able to pull appreciation rates in that specific area.
