ZIP Code 08865 Housing Market

📝 Local Market Notes

ZIP code 08865 in Warren County, New Jersey, exhibits a robust and accelerating price trajectory over the past five years. The Home Price Index (HPI) has risen from 167.83 in 2021 to 258.4 in 2025, representing a cumulative appreciation of approximately 54%. This sustained upward trend indicates strong underlying demand within the specific sub-market, with annual gains consistently outpacing the broader regional averages during the recent period. In the most recent year, the ZIP code recorded a year-over-year increase of +3.38%. This performance lags behind the Warren County average of +6.81% and the New Jersey state average of +4.53%. This divergence suggests that while the local market remains positive, it is currently experiencing a moderating effect relative to the wider county and state. The lower growth rate compared to the county median may indicate a shift in momentum or a saturation point for rapid appreciation in this specific pocket, distinguishing it from higher-growth areas like nearby ZIP 07838, which saw a +4.69% increase. The sub-market character of ZIP 08865 aligns with an established, owner-occupied residential community rather than an entry-level or renter-heavy zone. With a parent county median home value of $346,500 and an owner occupancy rate of 75.1%, the area reflects a stable housing stock. The HPI level of 258.4, significantly above the 2000 baseline, confirms that home values have more than doubled over two decades. For prospective buyers, the practical takeaway is that while prices have risen sharply, the current growth rate is cooling. With 30-year mortgage rates at 7.40%, the high absolute price levels necessitate careful budgeting, as the cost of entry remains elevated despite the slight deceleration in annual appreciation.
