How do I check whether a Moncks Corner agent has actually closed in my building or on my block?

Checking real activity on your specific block means asking any agent for a list of their closed sales there, then verifying those closings through public county records rather than taking their word for it. A citywide sales count says nothing about whether an agent has ever worked your specific Moncks Corner street. Brian can show you actual closed transactions in the specific area you are asking about, not a general resume.
