ZIP Code 01770 Housing Market

📝 Local Market Notes

The housing market in ZIP code 01770 exhibits a pronounced upward trajectory, with the FHFA Home Price Index rising from 165.99 in 2021 to 245.84 in 2025. This four-year expansion represents a cumulative increase of approximately 48%, indicating sustained and significant price appreciation. The most recent year-over-year growth of 14.61% underscores the continued momentum within this specific sub-market, distinguishing it from broader regional trends. This performance signals a sharp divergence from both Middlesex County and the state of Massachusetts. While the county recorded a modest 3.56% increase and the state grew by 3.63%, ZIP 01770 outpaced these benchmarks by nearly four percentage points. Such divergence suggests that local demand factors are driving prices independently of general regional economic conditions. In contrast, nearby ZIPs 02421 and 02459 experienced negative year-over-year changes of -6.49% and -2.84% respectively, further highlighting the unique strength and insulation of the 01770 market relative to its immediate geographic neighbors. Based on the parent county’s ACS data, which reports a median home value of $727,800 and a median household income of $130,847, ZIP 01770 functions as a high-value, owner-occupied sub-market. The 61.3% owner-occupancy rate supports a stable residential base, while the high income levels suggest a demographic capable of sustaining elevated price points. For prospective buyers, the combination of high income, low inventory implied by rapid price growth, and a 7.40% national mortgage rate creates a challenging entry environment. The data indicates that 01770 is not an entry-level market but rather a premium segment where pricing power remains firmly with sellers, requiring buyers to align their financial strategies with these elevated and accelerating valuation metrics.
