Zillow vs. Compass: How the Elite Broker Battle Is Artificially Inflating Prices for Buyers and Renters

Market pricing requires transparency. If you don’t know what other similar items are selling for, how can you know the fair price?

That goes doubly for real estate — and it’s the crux of the problem for homebuyers and renters in the battle between Compass and Zillow. The feud between the two real estate giants isn’t so much about two rivals competing for listings, but disputing which data should remain public rather than walled off.

Zillow’s business hinges on making real estate data public, and the more the merrier. Compass takes a different tack: They offer “private exclusive” listings (or pocket listings) only visible to their agents and customers, giving them first crack before the listings go live to the public on the MLS. 

“In response, Zillow created strict rules to block listings withheld from the public market, which led to lawsuits, antitrust complaints and platform blockages between the two,” explains realtor Ross Hardy. “That creates a fragmented market where Compass built its own ‘anti-Zillow’ ecosystem, syndicating private inventory to competitors like Redfin while keeping those homes entirely invisible on Zillow.”

For homebuyers and renters, that distorts the market because they can’t see the full inventory picture. It doesn’t directly push sellers to raise prices of course, but by limiting buyers’ information, it distorts supply versus demand and changes buyers’ behavior. 

Buyers and renters need critical information like days-on-market, price reduction history and previous pending sales. Private and fragmented listings take that information away from them, which undercuts their ability to negotiate. It also creates a two-tiered market, putting first-time buyers and out-of-towners at a disadvantage.

“Wealthy buyers well connected with local boutique brokerages see private properties before the general public ever gets a chance,” Hardy added.

Granted, an abundance of data can create its own distortions in the market. 

Zillow’s “Zestimate” figure estimating a home’s value remains notorious for over-valuing properties. That can lead sellers to overprice their homes and buyers to second-guess whether a home really is worth more than they thought. 

Realtor Lacey Perniciaro publishes Living Coastal, and points out that sellers buy into the Zestimate hype all too often.

“Zillow cannot see inside the house, can’t see the eight dogs and the air filters the seller never changed," according to Perniciaro. “It looks at square footage and the neighbor's sale two streets over.” 

A house is more than square footage, and Zillow’s estimate only sees the raw numbers. 

First and foremost, it helps to work with a real estate agent with deep local experience. By all means, use Zillow and Redfin and their vast databases of information — but don’t rely on them exclusively. 

Ask your agent questions like “Do you have access to private listings?,” and “How much inventory never reaches public portals?” Make sure they won’t try to steer you toward listings from their own brokerage. 

As you compare prices and rents, look for data like:

  • True days on market

  • Property condition

  • Recent comparable sales and rentals

  • Competing listings

  • Current and past concessions offered

Oh, and ignore properties’ Zestimates entirely. Think critically for yourself about what a property is worth, and negotiate aggressively. 

The Zillow versus Compass battle centers around who controls access to information. To protect yourself, pursue as much information as you possibly can, even when it means collecting it from multiple sources.
