Zillow doesn’t take into consideration the inside. It just uses algorithms to determine price based on year built, square footage, number of bedrooms and bathrooms, lot size, and the compares it to the recent completed sales of nearby houses. It’s not accurate but gives a general idea..
A house owned by someone very close to us is estimated at 50k. Which I doubt that’s realistic since the roof above the kitchen is sitting on the kitchen floor… another house owned by a relative has a Zestimate of 85k, and there’s open holes in the floor and ceiling to the point that mice fall on them at night. The camp next to my parents house needs to be completely remodeled, and has a Zestimate is 135k. The realtor valued the house at 60k.
Our Zillow is about 15% higher than the appraised value on the county tax maps
