Charlotte NC - 2 to 4 Unit Deals

Hello BP Community! I would like to learn more about the small multifamily rental market in the Charlotte, NC area. When I look for 2 to 4 unit properties for sale in the Charlotte area, I don't see much. However, when I look for apartments for rent, it seems that there are about 1,000 SFRs available in that area.

Are there not a lot of 2 - 4 unit properties available in the Charlotte market? If that's the case, where in that general area should I focus my search? Also, is it true that SFRs are more common for investors in Charlotte? I currently invest in Lakewood, Ohio which is overrun with duplexes and triplexes so I was shocked to see that there aren't any down in the Queen City.

Thanks in advance!
