One of my surfing buddies started a company that specialized in reducing property taxes. The last run up in home prices hurt his business but the market is in his favor now.We did and won. The County was using incorrect numbers to calculate how much we paid for our house. We were able to prove to the judge that we paid less than what the County's assessor was trying to lock us in at for tax purposes. The guys from the Assessor's office were shocked when we told them, fine, let's go to court. The judge looked at how we arranged our purchase contract and determined that we were correct and our tax bill was lowered ~ $500/year.
