I don't know how they figure prices. In my neighborhood a 2 bedroom 1700 sq. Ft. House sold for 490,000 dollars and the house across the street sold for 520,000 and it was a 3 bedroom 1730 sq. Ft. House. When you go on Zillow and check the price of my house which is 3 bedroom 1828 sq. Ft. House it's listed by Zillow as 426,000. The zestimates are completely inaccurate.
