• The last sale price is 98% below the current assessment. Massachusetts assessments aim at full market value as of January 1 of the year before the fiscal year.
• An Activity and Use Limitation is a deed restriction: it limits how the land may be used (often no residential use or no digging) and passes to every buyer.
