The number of home valuation websites continues to grow.
A simple Google search for "How much is my home worth?" shows 118,000 results and seems to get larger month after month.
For home sellers, these programs can give a false sense of security (or insecurity!) about at what price a home should be listed for sale.
Computer programs can never replace the role of licensed home appraisers and that's because valuing a home is not as simple as providing some inputs (traits) in order to get some output (value). There is a "fuzzy logic" that computer programs just can't produce in the same way that appraisers and real estate agents can.
Even with tax records, recent sales data, and a full description of a property, valuing a home is as much "art" as "science".
There are "human" considerations that include neighborhood quality and curb appeal that a computer can't measure. Nor can a program take into account how a kitchen may require $20,000 worth of work to bring it "up-to-date" or inline with neighbors' homes.
Besides, the real value of a home is what somebody is willing to pay for it. Therefore, you can never truly know what a home is worth until it has sold.
So, while automated valuation tools are a good start to finding a home's value, they're not equipped to finish the job.
YOU said when you talked about real value. Unless the appraiser, your banker, or your insurance agent are going to buy your house their opinions are not the real value
