Revaluation

Boro of Mountain Lakes

A reassessment of all real estate property in the Borough of Mountain Lakes is now being undertaken on an annual basis to ensure uniform and equitable assessments. Appraisal Systems Inc. (ASI) has made a complete analysis of all recent market data in order to accomplish this task and determine the value of all properties as of October 1, 2025. The market analysis of your property has been arrived at in accordance with the rules and regulations mandated by the State of New Jersey.

The aggregate value of total assessments in Mountain Lakes has increased for the 2026 tax year; therefore, the tax rate will change accordingly. For comparative purposes, a tax rate of $2.120 (per $100 of assessed value) has been estimated for 2026 to give property owners a sense of how their property taxes may increase or decrease based on the new 2026 proposed property assessments. This estimated tax rate does not include any potential budget increases in 2026, and the exact tax rate cannot be computed until the County, School and Municipal budgets are approved and calculated into the official 2026 tax rate next year.

If you desire, you may speak with an Appraisal Systems Inc. representative to discuss any relevant information regarding your new 2026 assessed value as it relates to the market value of your property. Meetings can be arranged by calling (201) 493-8530 Monday-Friday between the hours of 9:30 A.M and 4:00 P.M. Meetings will be conducted up through December 5, 2025, so please call as soon as possible.

Thank you for your cooperation during the reassessment process.
