I'm calling the county assessor's office this morning.

We received our property tax statement (a courtesy copy actually, since our mortgage company pays the property taxes) and about fainted!

I won't go into numbers, but this is what happened:

Land Value: value went down about 7-8%
Structure: value went up approximately 65% from previous year
Total RMV Value: went up approximately 30% from previous year

Assessed Value: went up approximately 45% from previous year

THEREFORE: Our taxes went up $1,000 from last year. Yes, you heard right. *thud*
