Zillow does nothing more than price comparisons and past sales and tries to predict trends. To be quite clear that home is not worth 1.9 or even 1.15 million. If is easily a 700k home but jacked up on the current inflated market.
Remember. Zillow does not have people sitting there trying to judge prices. It is done on pure raw data.
Zillow has caused as many headaches for the real estate agents and buyers. It is very inconsistent where it over prices some homes and under prices others.
Please remember these words next time.
A HOUSE IS ONLY WORTH WHAT SOMEONE IS WILLING PAY FOR IT.
