The internet is one of the best sources people use to get information on any topic, but it can also be misleading. Appraising a house with the help of the web does not always lead to the happiest results. Comparing similar properties in the area can work against sellers often. They may be tempted to ask for a price that is too high, but at the same time they might underestimate their property. It may seem adequate, but each property has its own pros and cons that influence value.
