Latest Monthly Snapshot
June 2026
Monthly Pricing Trends for Union County
Monthly data for the latest available year.
Monthly Inventory and Sales Activity for Union County
Monthly supply and activity totals for the latest available year.
Market gauge is calculated using active listings and pending sales from the most recently available reporting period (Jun 2026).
Union County is seeing steady listing activity even as closed sales pull back. Active listings in June edged up compared with May, while homes sold fell nearly a fifth over the month and more than a quarter compared with last year. New listings also jumped from May, suggesting fresh options for buyers even as overall turnover slows.
Pricing is adjusting to this flow of inventory and contracts. The typical home value in June rose solidly from a year ago, while the median list price dropped both month over month and year over year, pointing to sellers pricing more cautiously to attract offers.
Market balance has shifted toward neutral conditions. Months of supply climbed strongly from both last month and last year, landing just below the statewide level, and the share of homes selling above list price nearly doubled from May even though it remains under one in five. Homes are taking a median of just over three weeks to go under contract, much faster than late last year, and the average sale-to-list ratio is holding close to 98 percent, indicating limited discounting. Buyers can use these trends to negotiate thoughtfully, and sellers need smart pricing strategies, and Agent Pronto can help both buyers and sellers connect with an agent who understands today’s Union County market.
