Union County Real Estate Inventory and Supply Trends

Inventory is still tight, even with more homes on the market. There were 507 active listings in August—a 32% increase compared to last year, but still well below historic averages. New listings were the lowest since March, yet 14% higher than last August. With just 1.5 months of supply, conditions continue to favor sellers, though buyers will notice more options than they had a year ago.

Fall 2025 Real Estate Forecast for Union County NJ

Early fall often brings a bump in new listings before activity slows down for the holidays. That makes this season an appealing time for both sides of the market:

• Sellers can take advantage of low supply and motivated buyers.

• Buyers may see fresh options hit the market and face slightly less competition than in the spring.

If you’ve been considering a move, now could be a strategic time to get started.

I’ll be keeping a close eye on how the market shapes up this fall, and as always, I’m here to help you understand how these trends affect your specific situation. Thinking about buying, selling, or just curious about your neighborhood? Reach out anytime—I’d love to chat.
