You've probably spent hours scrolling through it. Everyone has. That glowing blue app is basically the default setting for anyone even remotely thinking about moving. But lately, there's been this nagging question bubbling up in Facebook groups and at kitchen tables: Is Zillow distorting the real estate market for the rest of us?
It’s a fair question.
When one company holds that much data, they aren't just reflecting the market. They're shaping it. Think about the "Zestimate." It’s become a household word, right? People treat it like gospel, even though it's just an algorithm guessing what your bathroom remodel is worth based on public records that might be three years old. This psychological anchoring is where the distortion starts. If Zillow says a house is worth $500,000, and the actual comps say $470,000, the seller is still going to walk into that listing appointment convinced they're being lowballed. It changes the starting line of the negotiation before a human being has even stepped foot on the property.
The Algorithmic Shadow: How Zestimates Move the Needle
Let’s get real about the Zestimate. Zillow itself admits it isn't an appraisal. They have a whole page dedicated to their "accuracy" where they track how close they get to the final sale price. In some markets, they’re surprisingly close. In others? They’re way off.
But accuracy isn't the only issue. The real problem is the feedback loop.
When millions of people use a single tool to determine value, that tool becomes a self-fulfilling prophecy. If a buyer sees a high Zestimate, they might be willing to bid higher. If a seller sees a high Zestimate, they won't settle for less. This creates an artificial floor for prices. We saw this get really messy during the iBuying era. Remember Zillow Offers? That was the peak of the company actually putting its money where its algorithm was.
They bought thousands of homes using their own data. Then, they realized the data was skewed.

By late 2021, Zillow shuttered its iBuying wing and took a massive financial hit—we’re talking hundreds of millions of dollars. They overpaid for houses because their own internal pricing models got too aggressive. When the biggest player in the room starts overpaying for inventory, it forces everyone else to pay more too. That is a textbook example of Zillow distorting the real estate market through sheer capital. Even though they’re out of the "flipping" business now, the data they provide still acts as the primary lens through which the average American views property value.
The "Premier Agent" Problem and Lead Diversion
You click a button to "Ask a Question" about a house. You think you're talking to the listing agent. You aren't.
Most of the time, you’re being routed to a "Premier Agent" who paid Zillow for the right to your phone number. This creates a weird barrier between the buyer and the actual facts of the home. It’s a pay-to-play system. This doesn't necessarily "distort" the price of a single house, but it definitely distorts the flow of information. Local expertise is being swapped out for whoever has the biggest marketing budget.
If you're a buyer, you might be getting advice from an agent who has never even been inside that specific neighborhood, all because an algorithm matched you. That leads to inefficient markets. It leads to people buying homes that don't actually fit their needs because the "expert" on the other end of the line is just trying to convert a lead they bought for $50.
Is Zillow Distorting the Real Estate Market Through Inventory Control?
There's this theory that Zillow hides certain listings or prioritizes others to manipulate what we see.
While there’s no hard evidence of "shadow banning" specific houses, their sorting algorithms definitely dictate what gets "hot." If a house gets 2,000 views in the first hour because of a push notification, it creates a "feeding frenzy" mentality. Buyers panic. They think, Oh man, 400 people have saved this, I better bid 20% over asking. Sometimes that house is great. Sometimes it’s just the one the algorithm decided to show everyone that morning.

In a traditional market, you’d rely on your Realtor to find the "hidden gems." On Zillow, there are no hidden gems. Everything is exposed to everyone at the same time. While transparency sounds good—and it usually is—it also eliminates the "quiet" market where deals used to happen. It turns every single sale into a high-stakes auction. This hyper-visibility is a major driver of the price spikes we've seen in suburban markets over the last few years.
The Psychology of the "Saved" Home
Psychologically, the "Heart" icon is a powerful thing.
When a seller sees that 150 people have "saved" their home, they feel empowered. They get greedy. Can you blame them? But a "save" on an app isn't a pre-approval letter. It’s often just digital window shopping. Yet, these metrics are used by sellers and their agents to justify holding out for higher prices, even when no offers are hitting the table. It creates a "sticky" price environment where values refuse to come down because the digital engagement metrics look so good.
What This Actually Means for Your Wallet
If you’re trying to buy a house right now, you have to realize that Zillow is a tool, not a teammate.
The distortion happens when we stop looking at the physical reality of a house and start looking at the digital profile. I've seen houses with terrible floor plans and cracked foundations get bid up because the photos looked incredible on a smartphone screen and the Zestimate was high.
- The "Coming Soon" Trap: Zillow often shows homes before they hit the MLS. This sounds like an advantage, but it often just builds up a massive backlog of buyers who all pounce the second the "Active" status hits.
- Data Latency: In a fast-moving market, Zillow can be 24-48 hours behind the actual MLS. In some cities, that’s the difference between getting a tour and finding out the house is already under contract.
- The Aggregator Effect: By pulling in data from everywhere, Zillow makes the market feel smaller than it is. It creates a sense of scarcity that might not be as intense as the app makes it feel.
Honestly, the biggest distortion isn't the price—it's the feeling of the market. It makes everything feel urgent. It makes everything feel like a competition. That's great for Zillow's engagement numbers, but it's exhausting for human beings trying to find a place to live.

How to Navigate a Zillow-Driven World
So, how do you actually win when the game feels rigged by an algorithm?
First, stop looking at the Zestimate as a price tag. It's a weather report. It tells you the general "vibe" of the area, but it won't tell you if it's raining in your specific backyard. You need to demand a Comparative Market Analysis (CMA) from a human agent who has actually walked through the recently sold houses in your ZIP code.
Second, look for the "Zillow blind spots."
These are the listings with bad photos, the ones that have been sitting for 30+ days, or the ones that don't have a 3D tour. Because Zillow’s algorithm prioritizes high-engagement listings, these houses get buried. That’s where the actual deals are. If the algorithm isn't showing it to everyone, you might actually have a chance to negotiate.
Third, check the "Days on Zillow" vs. "Days on Market." Sometimes these don't match. If a house was delisted and relisted to "reset" the clock, Zillow often catches it, but not always. Use that data to your advantage. If you see a house has been "on the market" for 5 days but has a price history showing it’s been floating around for six months, you have leverage.
Actionable Steps for Navigating Market Distortion:
- Cross-reference everything: Never rely on one site. Check Redfin, Realtor.com, and your local MLS portal. They all pull from different feeds and refresh at different rates.
- Ignore the "Hot Home" badges: These are often based on click volume, not value. A house can be "hot" because it's a disaster that everyone is sharing to laugh at, not because it's a good investment.
- Verify square footage: Zillow often pulls from tax records which can be notoriously wrong. If a basement was finished without a permit, the "price per square foot" calculation on the app will be completely skewed.
- Talk to neighbors: No algorithm knows that the house three doors down is a frat house or that the street floods every time it pours. Physical due diligence is the only cure for digital distortion.
The reality is that Zillow isn't going away. It’s too convenient. But by understanding that it’s a marketing platform first and a data provider second, you can start to see through the noise. Don't let a "Save" count or a computer-generated number dictate what you're willing to pay for your future. The market is distorted, sure, but only if you choose to see it through a single lens. Expand your view, do the manual labor of research, and you'll find that the "Zillow effect" loses its power pretty quickly once you're standing on the actual front porch of a house.
Stop scrolling for a second. Go look at the actual property. That's where the real market lives.
