How values are spread across Roslyn School District

A quarter of homes sit below the 25th percentile and a quarter above the 75th. A home near the top isn’t over-assessed because of that alone; it may simply be larger, newer, or on more land.

One-to-three family homes with a recorded value on the 2028 tentative roll, rounded to whole dollars. Homes with no recorded value are left out.

What these figures mean, and what they don’t

  • A median is not your value. It marks the middle of 5,353 homes that differ in size, age, condition, and lot. Your own record may be well above or below it for good reasons.
  • The roll is tentative. It is the County’s first published figure for the year. Values can change through corrections and appeals before the roll becomes final, and this page will be refreshed when a newer roll is imported.
  • Verify with the County. Check any figure that matters to you in the Nassau County Land Records Viewer. This page summarizes published records; it is not an appraisal.

The calculator and homeowner guide run in your browser. We don’t collect your answers, and we don’t use advertising trackers. If you ask for a filing-window reminder, a message if records for your town are added, or a watch on a property, we store the email address you enter, your name if you give it, the property address the request is about, the kind of message you asked for, and the page you asked from. For a property watch, the address and property record come from the County record you were viewing; otherwise it is the address you typed, which a failed search fills in for you. We use these details only to send that message. The property checker does not keep the addresses you search unless you ask for a notice.

The property checker sends the address you enter to our service to find matching County records.

If you choose “Show my area instead,” your browser asks before sharing your location. We round it to about ten metres, use it once to find your school district and neighborhood, and don’t store or log it.

We use self-hosted, cookieless Umami analytics to understand aggregate site visits, guide opens, and whether property searches return results.
