ZIP Code 03773 Housing Market

📝 Local Market Notes

ZIP code 03773 in Sullivan County, New Hampshire, exhibits a robust upward price trajectory, with the FHFA House Price Index rising from 232.72 in 2021 to 360.82 in 2025. This represents a cumulative appreciation of approximately 55% over four years, indicating sustained demand within this specific sub-market. The most recent year-over-year growth of 7.27% further confirms that momentum remains strong, outpacing broader regional trends. The performance of ZIP 03773 demonstrates a clear divergence from both the parent county and the state. While Sullivan County recorded a 3.91% increase and New Hampshire saw 3.11% growth, the 7.27% gain in 03773 suggests localized factors are driving premium pricing. This outperformance relative to the county average signals that this specific area commands a higher valuation, likely due to distinct local amenities or limited inventory. In comparison to nearby ZIP 03781, which posted a 9.66% increase, 03773 remains a high-growth area, though slightly less aggressive than its immediate neighbor. Based on the parent county’s median home value of $268,700 and a 75.4% owner-occupancy rate, the broader Sullivan County market leans toward owner-occupied, mid-range housing. However, the HPI level of 360.8 in 03773 indicates this specific ZIP functions as a higher-value segment within that context. The high owner-occupancy rate suggests a stable, long-term residential base rather than a transient or renter-heavy environment. For prospective buyers, the data indicates a competitive market where prices are appreciating at nearly double the state average. With the 30-year mortgage rate fixed at 7.40%, the rapid price appreciation in 03773 significantly impacts affordability metrics. Residents should anticipate continued pressure on home values, as the local market is currently decoupling from the slower growth observed in the wider county and state.
