There could be various reasons why your home value is dropping on Zillow. Factors such as algorithm changes, missing data, market shifts, or even incorrectly listed information can affect the accuracy of Zillow’s estimates.
Consulting a professional realtor for a comparative market analysis (CMA) is recommended to assess your home’s value more accurately.
From experience as a Realtor for the past three decades, you should take Zillow home values with a grain of salt. I will let you in on a dirty little secret. They are not accurate.

Zillow home values will go up and down like the wind.
What is The Zillow Home Value Estimator?
A Zillow home value estimate is a rough calculation of a property’s market value provided by Zillow, a popular online real estate marketplace.
Zillow uses a proprietary algorithm, often called “Zestimates,” to calculate these estimates. The algorithm considers recent sales of similar properties in the area, tax assessments, and other market data.
Zillow home value estimates are not appraisals and should not be considered as such. It’s important to note that they provide a general idea of a property’s worth. It should be clear they may not always be accurate or up-to-date.
Inside Zillow’s Estimation Algorithm
For example, a homeowner could remodel their house with premium finishes but might end up with an undervalued estimate due to insufficient data.
Algorithms cannot capture unique characteristics humans can use to calculate a property’s worth.
It’s also important to note that while the algorithm provides an estimate that considers various data points, both objective and subjective, actual appraisals and professional opinions are essential in significant transactions.
Consulting with a professional real estate agent or appraiser is always recommended to assess a property’s value accurately. An appraiser will look for many things an algorithm cannot assess.
Key Takeaway: I constantly explain to my clients not to be concerned with Zillow’s opinion. Plenty of other real estate agents do the same to educate the public. So, don’t stay up at night worrying about a buyer making a lowball offer.
Examining Zillow Home Value Drops
Zillow is one of the most popular platforms for homeowners to estimate their home’s value, with their metric known as “Zestimate.” However, Zillow recently released a report that forecasted a drop in home prices in 34 of the 50 largest cities in the United States.
Many homeowners rely on Zillow to inform them if their property values increase or decrease. So, it is crucial to examine the accuracy of these estimates.Click To TweetMarket Influences on Zestimate Accuracy
Recognizing that Zestimates are estimates based on the available data is essential. They are not always an accurate reflection of a home’s actual value. Many factors influence property value fluctuations, including economic changes, housing market trends, and neighborhood conditions.
Suppose you’re selling your home and input your address into Zillow’s database to know its worth. The proprietary software composes the platform’s algorithm and generates an estimate.
It compares primary data sources like local tax assessments and public records against active listings and recent sales in your neighborhood.
However, it is crucial to keep in mind that this estimated value is dependent on many variables, such as:
Factors For Accuracy
| Factor | Description |
|---|---|
| Location | Neighborhood growth/decline |
| Economics | Mortgage interest rates and unemployment rates |
| Age | Property age and improvement over time |
| Size | Square footage of the house |
| Amenities | The presence of parks, hospitals, and schools in the vicinity |
One example is location; this can significantly impact an estimate’s accuracy. For instance, homes near parks, schools, or sought-after communities often have higher values than those farther away from amenities and services.
Therefore, if your home isn’t similar to other recently sold houses within a half-mile radius of yours or has just undergone a remodel or renovation, the estimated value could be significantly off.
Some of the factors that can influence Zestimate accuracy include:
| Factor | How it Impacts Accuracy |
|---|---|
| Zoning Changes | These changes shift property values |
| Market Activity | Recent sales data and listing prices affect estimates |
| Public Record Errors | Inaccurate public records create discrepancies |
| Neighborhood Changes | Shifts in local amenities or crime rates impact property value |
Zillow’s Zestimate FAQs state that their estimations should merely be used as an initial starting point. To gain a more realistic understanding of the home’s actual value when selling or buying, homeowners should consult a real estate agent to ensure a comprehensive understanding of local market conditions.
Listing Your Home For Sale
Once you decide to list your home for sale, Zillow immediately incorporates the listing data into its algorithm to calculate an estimate of your home value.
Please note that the listing data solely affects this estimation and is unavailable for off-market homes.
Thus, you will only influence the estimate once you officially list your home for sale. You could see your Zillow value drop when it goes on the market.
Your Asking Price Gets Set in The MLS
Your Zillow estimate can be affected when you establish a listing price for your home. Additionally, the estimate may be adjusted if you increase or decrease the listing price.
Previously, Zillow emphasized that the list price does not influence its Zestimates. They have said their primary goal is to monitor the market rather than influence it.
Nevertheless, Zillow’s algorithm occasionally considers the list price a helpful indicator. This is especially true when other data is lacking, and the Zestimate is adjusted accordingly.
From my observations as a Realtor, the value has fluctuated when there is a price change.
There Are Missing or Inaccurate Facts About Your Home
Another way your Zillow home value could be lowered is when the information about your property is incorrect.
If Zillow lacks certain information about your home, it is possible that your home value estimate could be lower than it should be. To enhance the accuracy of your estimate, you can follow these steps:
- Make corrections to any mistakes in their data.
- Edit the features of your home to reflect the present condition accurately.
- Check off the boxes for all the amenities on your Zillow profile.
- Add any updates to your local tax assessor, like additions or remodels. Zillow eventually picks up the information.
Local Area Home Sales Impact Your Zestimate
Zillow uses data from nearby homes to determine the value of your property. If houses in your vicinity are being sold below the market value, this will impact your home’s estimated value.
Zillow’s algorithm utilizes various sources of data to generate an estimate of your home value. This includes obtaining your home’s square footage from tax records and analyzing recent home sales in your local area.
However, it’s important to note that this comparison does not consider building materials, home style, improvements, higher-end kitchens and baths, and your lot. All of these items can potentially increase your home’s value.
It is one of the significant reasons Zillow values often don’t align with the actual value.
The Local Real Estate Market is Shifting
It’s also possible Zillow sees changes afoot.
Your estimate may have gone down because the market is shifting. Zillow can modify your home value estimation based on current market conditions.
Typically, homes have a higher value during a seller’s market than a buyer’s market. If you previously checked your Zestimate during a thriving seller’s market and then rechecked it when the market became less favorable, there is a possibility that your home value may have decreased.
Property Alterations Impacting Value
As a homeowner, it’s essential to understand that not all renovations will yield positive returns. Some home improvements may even hurt your chances of fetching decent sale prices.
Common alterations that impact property value include structural changes like adding new rooms or converting spaces such as garages into rooms.
Additionally, adding a pool might appeal to more significant luxury properties, but it often fails to impress potential buyers.
Factors such as problematic layouts that reduce livable square footage and outdated bathrooms or kitchens can also decrease home value. Therefore, homeowners should consider consulting experts before embarking on any significant renovations.
One of the things I am constantly discussing with my clients is what not to improve when selling. There is no sense in wasting money. It’s all about ROI and saleability.
For instance, adding unique features like wallpaper and particular colors shouldn’t be considered safe bets for improving property value. Instead, make investments aimed at improving functionality and maximizing space.
Understanding Zillow’s Data Sources
Zillow has become one of the most utilized online real estate companies. Potential home buyers regularly use the site, saving their favorite properties.
The platform provides users valuable insights regarding home values, typically estimated using public records data combined with proprietary algorithms.
Although there are limitations to how accurate Zillow’s data is overall, understanding the company’s data sources is still crucial.
Public records: Zillow gets information about property transactions such as sales history, tax assessments, and liens from public records databases.
Proprietary Algorithms: Machine learning algorithms analyze these transactions to identify patterns and trends in similar properties using factors such as location and age to estimate your home’s worth compared to other nearby homes.
You can think of it like baking a cake. You need different ingredients mixed in a specific recipe to achieve a perfectly golden crust.
Similarly, Zillow combines elements from various sources to create accurate projections of what a home is worth based on market analysis.
However, as mentioned, these estimates are not always 100% reliable. Zillow’s algorithm is useful primarily for getting an idea of what your home might be worth in the current market. When assessing the value of a specific property, it’s crucial to work with a real estate agent familiar with the area’s market.
Assessing Zillow Home Value Credibility
Zillow offers considerable help for prospective homeowners by providing instant home value estimates using proprietary technology.
However, it’s essential to consider that inaccuracies or incomplete facts may result in incorrect estimations.
To honestly assess credibility, comparing Zestimates offered by the platform with professional appraisals can provide clarity. Professional appraisers use advanced software and experience to find more precise home valuations.
They use real estate comps based on years of experience. They know what hurts the appraised value of a house and can make adjustments accordingly.
Zillow doesn’t know about red flags impacting a home’s worth.
The human eye and computer analysis provide ample opportunity to minimize errors.
For better comparison, let’s explore some key features of traditional appraisals and Zestimates in a table:
Comparing Appraisals to Zillow Zestimates
| Key Features | Traditional Appraisal | Zestimate |
|---|---|---|
| Review Process | A licensed appraiser physically walks through your home and assesses its floorspace, quality of construction materials used, and finishes. They then compare your home with recently sold homes having comparable features. | A proprietary algorithm analyzes public records on home sales, tax assessments on properties, and other data to estimate a home’s worth. |
| Accuracy | Values assigned are based on the physical characteristics of the home itself, its condition, location, and recent market trends. The accuracy will depend on the expertise of the appraiser and how up-to-date their data is | It’s estimated that Zestimates can be off by as much as 20% of the actual home value. However, this varies depending on location and other factors. |
| Cost | Appraisals typically cost between $300-$500 per property, depending on location and property type. | Zestimates are free estimates of your home’s value on Zillow’s website or mobile app. |
Of course, every approach has its pros and cons. Traditional appraisal processes can be time-consuming and costly. Using proprietary algorithms to estimate can save homeowners time and money.
It’s essential to remember that both methods offer valuable insights into your home’s value. However, professionally appraised properties usually command more credibility during transactions.
Consider how an athlete may need endurance training (Zestimate) and strength training(Professional appraisal) to achieve optimal fitness results.
Comparing Zillow to Real Estate Agents’ Appraisals
Using Zillow to base pricing decisions when buying or selling is a significant mistake.
Zillow’s proprietary home valuation tool, Zestimate, has faced backlash from professionals and property sellers for its unreliable estimate of a property’s worth.
Many real estate agents claim these estimates are inaccurate and can mislead potential buyers and sellers. The reason is that a property’s appraisal process considers several critical factors.
The property’s age, maintenance, and market conditions that computer algorithms alone cannot accurately predict.
Using Zillow’s estimates as a substitute for a local agent’s appraisal is similar to substituting WebMD instead of an in-person exam with a doctor.
While these estimates provide a starting point when searching for properties in your desired location, they should not be used as the sole source of information.
An accurate appraisal by trusted professionals remains the gold standard for determining home value.
- According to Zillow, approximately 3 out of 4 homes in the U.S. are estimated with 20% accuracy. It indicates a potential for significant fluctuations in home value estimates.
- Zillow reports that their Zestimates had a median error rate of about 2.4% for on-market homes and 7.49% for off-market. These inaccuracies could lead to significant misunderstandings about property values. Others report they are off by much more.
- An analysis by the National Association of Realtors found that online estimates can give a general idea about the value of a home. However, they can be off by as much as 30% due to changes in market conditions, listing prices, or missing data.
Boosting Your Zestimate: Practical Strategies
Although Zestimate isn’t perfect, homeowners can do various things to increase their chances of obtaining an accurate evaluation. You can use practical strategies to help improve your Zestimates.
Start by familiarizing yourself with Zillow’s database and how it works. This includes ensuring updated information on your property is available online.
Photos, descriptions, and other vital information must be updated so potential buyers or renters can get an accurate picture.
Pay attention to every available feature within the platform. This could range from adding high-quality photographs to virtual tours and floor plans.
Remember that markets change constantly, so your home value could also be affected. Therefore, schedule updates to make adjustments.
Lastly, be proactive about responding to inquiries regarding your property. Answering questions openly and honestly builds trust and helps buyers make informed decisions.
