Union County Real Estate Market Update September 2025
Homes Selling Fast and High
As Labor Day signals the shift into fall, Union County's real estate market remains remarkably resilient. Buyers and sellers alike are navigating a landscape marked by continued price growth, recovering but still tight inventory, and strong demand—especially in commuter-friendly and high-amenity towns.
Here’s the latest snapshot and what lies ahead for the close of 2025.
1. Price Trends: Holding Strong, But Slowing Slightly

Takeaway: Price growth remains robust, though broad-based data suggests a gradual tempering—indicative of a shift from the frenzied early‑2025 pace.
2. Inventory & Sales Pace: Cautious Optimism

Redfin
Takeaway: Inventory is improving but, limited. Homes continue to sell quickly and for more than the list price, reinforcing a persistent seller’s market.
Key influencers:
- Mortgage rates expected to remain elevated (30-year fixed rate around 6.5% to 6.8%), dampening buying power—but not halting demand entirely.
- New listings are likely to continue increasing through September, offering buyers more options—but expect competition to remain stiff.
- Seasonal slow‑down typically softens activity in November and December; buyers might find short-lived negotiation leverage if demand wanes.
- Affordability pressures will continue influencing mid-market dynamics. Luxury and commuter-adjacent towns may remain resilient even as broader demands cool.

Inventory is inching upward, yet homes are selling quickly. Through the end of the year, prices are expected to continue increasing modestly, setting the stage for an active and tactical fall market.
