Local Market Context
The agent market concentration in Union, SC, is further illuminated by the distribution of homes sold. With a total of 59 homes sold in the trailing 12 months, the fact that the top 1% of agents secured 34.1% of the sales volume implies a substantial share of these limited transactions. This means that a very small number of individual agents are closing a significant portion of the deals in the county. Similarly, the top 20% of agents collectively accounted for the 67.2% sales volume, translating to a large share of the 59 homes sold. This dynamic can create a challenging environment for newer agents or those looking to break into the market, as established players already command a strong foothold.
This strong concentration in Union County stands in contrast to larger, more fragmented markets where agent shares might be more evenly distributed. In a market with a relatively low number of transactions like 59 homes, the influence of a few high-performing agents becomes magnified. This could be due to several factors, including established local reputations, specialized market niches, or strong referral networks that allow them to capture a larger portion of the available listings and buyer demand. Such a landscape often means that a few key agents become central figures in local real estate, acting as gatekeepers or primary sources for market intelligence.

Their expertise in a concentrated market can be invaluable for identifying prime properties, understanding local pricing nuances, and executing transactions efficiently.
