How does Zillow come up with their Zestimate on homes for sale?

Profile picture for reputablebuilder
The reason I ask is that I have a new construction for sale, and they have it $50,000 lower than our asking price, which is basically setting us up for an offer that is $50,000 under what the house is worth.  Estimates like this are going to put builders out of business!  You can't take less than what you have in a house, come on!  Look at the pictures.  We don't play car salesman games with our pricing, we are very fair in our pricing.

    I've roofed 10:12 pitched roofs.  I've set forms in 110°F, but in most cases find it better set the forms at 7:00 am rather than 3:30 pm.  And really, those building conditions have little to do with what people want to pay or what the competitive pricing is.

    Are you using solid heart redwood for all framing?  If not, you don't meet my specifications.  And I'm not buying in areas that have 100°F ambient temperature anyway.

    If people want sources for "justifying" their low-ball offers, there are plenty of them, so it doesn't matter what Zillow's opinion is.  Ultimately, it still comes down to what the market demand is.  If a serious buyer loses out on too many offers, they quickly re-adjust their thinking to actual market conditions.

    By the way, who does your soil compaction testing?

You obviously are not a builder, or you purchased a low quality new construction in the past.  I was just frustrated to see this zestimate on our property that so much thought and hard work went into.  We have been building homes for more than 20 years in the same town, and we use only the best materials.  We are a small business , and we handle every piece of lumber or concrete that goes into every home.  We know very well how to refuse low ball offers, our homes quality and style speaks for itself.  I think the people that make low ball offers should spend a few days setting basement forms in 100 degree weather, or walk on a 10-12 pitch roof and shingle it , their values would likely change.

By the way, don't forget that just because someone spent a given amount on a property and development, that doesn't mean they can necessarily get that out of a sale of the property, let alone overhead and profit.

All developers factor those things in ahead of time when they take their risks to build; but it is not always possible to anticipate market changes.  That is just one of the risks of the business, and the reason developers try to keep abreast of trends, and estimating techniques, and estimating data.

Zillow absolutely doesn't care if a house is new or for sale or not in their estimates.  They simply model the non-distressed recently sold property amounts to the county records data, then test those sales against the model eliminating any that don't fit the model well; then recalculate the model, then use the model to extrapolate "opinions of approximate value" from the public records data.

Anyone looking at the "opinions" knows they are just machine opinions without any ability to "look" at anything inside nor out, and that offering based on one set of machine generated opinions and ignoring dozens of other machine opinions available from other AVM sources available, and ignoring the advice and opinions of the buyer's agent, and ignoring the appraiser's approximations, only means that the buyer's offer will be "rejected", or that the buyer may overspend without cause.

If you don't know how to say no to low-ball offers, you certainly cannot blame that on your local newspapers or any other media outlet that offers classified listings.

By the way, what is putting builders out of business has nothing to do with the present economy nor any estimates, it is related to NAR propaganda leading to a housing bubble, and overbuilding by most builders between 1999 and 2006, thus creating an over-saturated market condition.

The real question is why a buyer would pay $50k extra for "new", when they can get quality used that has been broken in already, and often has better quality materials and construction without having to put up with noise and dust from continuing development in the area?
