📝 Local Market Notes

The housing market in ZIP code 04843 exhibits a volatile price trajectory over the recent five-year period. The Home Price Index (HPI) surged from 210.49 in 2021 to a peak of 378.52 in 2024, representing a substantial appreciation phase. However, the most recent data for 2025 indicates a sharp correction, with the HPI declining to 344.65. This recent drop signifies a significant reversal of the prior upward momentum, distinguishing the local market from the broader regional trends currently observed in Knox County. This divergence is stark when compared to surrounding metrics. While ZIP 04843 recorded a year-over-year decline of 8.95%, the parent Knox County experienced a 3.76% increase, and the state of Maine saw a 0.98% gain. Nearby ZIP codes, such as 04862 and 04856, also posted positive growth rates of 5.56% and 4.54%, respectively. This negative divergence suggests that ZIP 04843 is undergoing a localized adjustment that contrasts with the general stability and growth of the wider county. The specific nature of this correction, occurring amidst a national 30-year mortgage rate of 7.40%, highlights a distinct sub-market dynamic that is currently decoupling from county-level performance. Regarding sub-market character, the parent county’s median home value of $324,900 and median household income of $74,096 suggest a middle-income residential area. However, the high HPI level in 04843, relative to the county average, indicates that this specific ZIP code likely contains higher-value properties or a different inventory mix than the county median implies. With an owner-occupancy rate of 78.7% in the county, the area leans toward owner-occupied housing rather than a renter-heavy market. For prospective buyers, the current 8.95% year-over-year decline in ZIP 04843 presents a potential entry point into a market that has recently corrected from its 2024 peak. Residents should note that while the broader county remains stable, this specific ZIP is experiencing a distinct price adjustment, requiring careful evaluation of individual property values against the recent downward trend.
