The Greensboro housing market is right now on the upward swing. We have a very low amount of inventory of homes for sale. Many buyers are having to move quickly when they do find the home they want since the amount of available homes for sale is low. As far as a safe investment real estate is traditionally a good long term investment. There are even companies/investment groups from as far away as California buying up homes here to use as rental properties.
As to you question about is an area "safe" Emily is correct as NC Licensed Brokers we are not allowed to comment on attributes about an area whether it is demographic makeup, crime, or anything. We can however be the "source" for the information you need to make the right decision for you and your family. The website Emily mentioned Spotcrime.com is a good site you can put in an address or an area and tell it a radius (1 mile or more) and it will tell you all the reported incidences for that area and then if you like it will send you a daily email updating you.
You can also contact the local Sheriff's department or the local municipality that you are searching in (local city police) to enquire about crime statistics. Trulia even has some crime statistics built in to their demographic information about areas. If you want detailed demographic information such as age range, and much more info you can actually look at Zipskinny.com for that. If you want to know about Senior centers, activities, or help with finding a home feel free to contact me through my profile here on Trulia.
Hope this helps,
