KEENE MASS APPRAISAL CONSULTING

Notable Achievements and Experience

When I started with the Philadelphia office, there was no standardized mass appraisal process. Values were whatever the assigned appraiser thought they were. There was no CAMA system; no sales validation process; no modeling process; no assessment performance metrics; no interactive computer access to property records. Everything was accomplished by passing hand-written forms. When I was assigned to a special unit to explore the viability of using computers for mass appraisal, I began a journey that would transform the way the office operated which led to dramatic improvement in the fairness, equity and accuracy of estimates of market value.
