A typical home seller in the U.S. in 2017 was 56 years old. They had lived in their house for the last ten years and had a median income of 107 thousand dollars. While the median age of a first time home buyer was 33, and 47 for a repeat buyer, with respectively 80 thousand dollars and 106 thousand dollars of income. The standard home bought was 1,900 square feet in area, was constructed in 1993, and had three bedrooms and two bathrooms. And on average, 88% took a loan to finance their purchase. Needless to say that, for such a substantial debt contracted, the actual price negotiated has to be as close as possible to the fair market value.

The goal is to see whether Quaartz can estimate the home selling price accurately. The price estimation has been mostly dependent on the realtor’s evaluations. However, it is precious for a home seller and a realtor to get a quick, independent, objective estimate in a few clicks.

Quaartz has selected the following four criteria out of the eight available in the dataset to make its home price evaluations:
In 2018, 8% of homes were sold by their owners. Owners selling their home by themselves say that getting the right price and selling within the planned length of time was among the most challenging tasks. Finding the right selling price and optimizing it against the time required for selling are challenges. The live predict feature of Quaartz can help model this.
