My take for buyers, sellers and renters

• Buyers: a below-county-median effective tax rate stretches your budget further here than in many Somerset towns. Compare with the town comparison tool.
• Sellers: with fewer public market indexes for Peapack and Gladstone, a comparable-sales analysis matters more. Get a free home value.
• Low turnover: about 1 residential sales were in the state’s 2026 report, so good listings can be scarce. Set alerts and be ready to act.
