What is a home safety score?
The home safety score (0-100) combines multiple environmental risk factors into a single number: water quality grade, lead contamination levels, flood zone exposure, radon risk, and air quality. A higher score means lower overall risk. The score helps homebuyers compare neighborhoods at a glance. Princeton scores 36/100 with a "high" risk level.
What is the equity trap ratio?
The equity trap ratio measures estimated remediation costs as a percentage of median home value. A high ratio (above 5%) means fixing environmental issues could consume a significant portion of your home equity — a potential "trap" for buyers unaware of hidden costs. Princeton's equity trap ratio is 5.0%, which is considered high.
