Hi, As per the previous answer. It is, indeed, a slow search.
Our Barnstable County, Ma. Registry of Deeds does have free- online search capacity , but one can not print info unless you join site.
All Cape town Assessors have "Field cards" show prior assessments (but only 2 years back).
These are free & online on Brewster town site ( click assessors database search).
Many of my recent clients are seeking past assessments for basis for offers based on same formulas.
happy to assist further,
