1. Properties are bought/sold constantly around most people's homes. Evaluating a home price is not that hard, compared evaluating how much the remains of the car that Ted Kennedy crashed is worth (I purposely chose this example. The car is "worthless" yet I guarantee you can find a nut willing to spend a fortune to have this piece of political history)

2. Properties are purposely, often by statute, assessed far less then they are bought for

3. There are tons of lawsuits around this, imagine the cost of every asset being scrutinized and potentially appealed!
