I just got a letter that the assessed value of my house went up $38,000 dollars from last year! I live in Waukee and my taxes are already high. I would try to dispute this, but I finished my basement a few years ago and the assessor doesn't know it is finished so my value would go even higher. I am not suprised my value went up, but that is a huge increase. Has anyone else noticed their taxes going up so much?
