There are differences between individual properties and neighborhoods. One neighborhood may have sales that indicate a change in value, while sales in another may not reflect any change at all. Different types of properties within the same neighborhoods may also show different value changes. For example, one-story houses may be in larger demand than two-story houses, or vice versa. Older home values might rise slower than newer homes.
There are numerous factors to be considered by the assessor when reviewing property values, thus causing different areas and types of properties to change values at different rates.
