“With Matrixian, we have developed a wonderful assessment system for WOZ values, with which our members can advise their clients via a simple test whether it makes sense to object to a WOZ assessment. If you first send an appraiser out to have a report written, you can easily spend a few hundred euros without knowing whether it will make any difference.” Read more here.
