Grass Valley, and Nevada County as a whole doesn't really have bad areas. There are alot of nice areas, but it really depends on what type of property you want. Do you want acreage, or more of a neighborhood feel? There is also areas that have both. What price range are you looking in? I can send you a sample of what's in the different areas. You can also go to my website www.livingnevadacounty.com and read about the different areas and search for properties. Let me know if you'd like more help or information.
