How long should title search take in North Carolina?

[Terrance Merck]

I am wholesaling and recently assigned my contract to buyer. The property is owned free and clear with owner owing some taxes on property. I reached out to an attorney for closing and am currently waiting on title search and closing date. The attorney informed that process would take about 2 weeks. It has been 3 weeks. What is the normal time frame for  title search and closing process? Is this a normal time frame? The attorney informed that they also have other title searches that their researchers have and that I will be notified as soon as search is complete. In the meantime my buyer and seller are getting anxious. 

All input is appreciated.
