WASHINGTON COUNTY PROPERTY VALUE RISK ASSESSMENT

See How Much the Proposed ICE Jail Could Cost You

In January 2026, the Department of Homeland Security purchased an 825,000 sq. ft. facility in Williamsport to convert into an ICE detention facility. A landmark peer-reviewed MIT Press study found that new correctional facilities significantly decrease nearby residential home values.

PEER-REVIEWED RESEARCH

The Economic Science Behind the Calculator

In November 2024, MIT Press published a comprehensive national econometric analysis titled β€œThe Local Impacts of Prisons” in The Review of Economics and Statistics.

Empirical Methodology

Researchers analyzed decades of national housing transactions surrounding newly opened correctional facilities, controlling for county-level economic trends, interest rates, and demographic shifts.

Distance-Decay Gradient

The negative impact is greatest closest to the facility: home values fell by 3.4% within 1.24 miles with high statistical certainty (p < 0.01), and 1.8% within 2.49 miles.

Unanalyzed Public Burden

DHS has provided no public economic impact assessment or compensation mechanism for the multi-million dollar asset devaluation imposed on Washington County property owners.

COMMON QUESTIONS

Frequently Asked Questions

How does this calculator determine my home's valuation?

When you submit your street address, the tool locates the exact property parcel through the Maryland Department of Planning's official iMAP / SDAT (State Department of Assessments and Taxation) records. It retrieves the official full appraised property value on record for tax year 2026 and applies the distance-based loss percentage identified in the MIT Press research study.

Where do the percentage loss figures (3.4%, 2.0%, 1.8%) come from?

These figures come directly from "The Local Impacts of Prisons", a peer-reviewed empirical study published in November 2024 in The Review of Economics and Statistics (MIT Press). The researchers analyzed home transactions across the United States before and after new correctional facilities opened, identifying a statistically significant drop of 3.4% within 1.24 miles and 1.8% within 2.49 miles.

Is my address data saved or tracked?

No. Your address is sent securely in real-time only to match U.S. Census coordinates and Maryland public GIS property records. Neither this website nor any third party stores your address, search history, or property calculation.

What if my home is outside the 2.49-mile boundary?

The study found that beyond 2.49 miles, price declines were not statistically significant at standard scientific thresholds (e.g. at 3.11 miles). The calculator therefore reports zero assigned reduction for addresses beyond 2.49 miles to maintain scientific integrity. However, broader regional economic and traffic impacts may still affect the wider area.
