    Thank you and CPTM for your successful efforts to win an abatement for our property. I guess you really can fight city hall (even if it does take a couple of years). I’m happy to pay your contingency bills.

    Year after year, CPTM continues to provide outstanding service. CPTM’s team members consistently demonstrate in-depth knowledge of current assessing practices, general conditions and trends within the markets they service, as well as changes in statutes that affect our portfolios. In addition, CPTM meshes this with the ability to review values, determine aggressive targets and ensure that appeals are filed in a timely fashion. These strengths, along with the professional relationships that have been built with the local authorities, ability to effectively communicate on pressing issues, and aggressive stance with our company’s best interest in mind, provides me with the high level of comfort we expect for a tax management company.
