Did you have any remodeling, new construction, or additions done to your property last year? Then this affects the WOZ value.
We use cetrain dates for determining the value
The property value is the value of the property from January 1 of the previous year. We call this the 'waardepeildatum'. We then look at the condition of your home on January first of this year. We call this the 'toestandspeildatum'.
