Zillow
FreeOnline real estate marketplace featuring home listings, Zestimate valuations, mortgage tools, and neighborhood data for buying, selling, and renting properties across the US.
What does this tool do?
Zillow is the dominant online real estate marketplace in the US, serving as a centralized hub for property discovery, valuation, and transaction facilitation. The platform aggregates millions of residential listings from multiple sources, allowing users to search properties by location, price, features, and school districts. Its signature Zestimate feature provides algorithmic property valuations based on comparable sales, property characteristics, and market trends—though these estimates carry inherent uncertainty and often diverge from actual appraisals. Beyond listings, Zillow offers integrated mortgage calculators, pre-approval tools, neighborhood analytics including crime data and walkability scores, and direct connections to real estate agents and lenders. The platform has expanded into property management and rental markets, positioning itself as a full-cycle real estate ecosystem rather than a simple listing directory.

Pros & Cons
Advantages
- Largest US real estate listing database with near-complete market coverage, providing visibility into most available properties and enabling accurate market comparison
- Free Zestimate valuations and neighborhood data lower barriers to entry for casual browsers and first-time homebuyers without requiring agent consultation
- Integrated mortgage tools, pre-approval calculators, and lender marketplace streamline the financing process within a single platform rather than forcing users across multiple websites
Limitations
- Zestimate valuations are frequently inaccurate by 5-20%, particularly in specialized markets or rural areas, potentially misleading sellers on asking prices or buyers on fair value
- Limited transparency on how recently listings were updated or verified, sometimes displaying sold properties or delisted homes as active, creating friction for serious buyers
- Real estate agent recommendations are often based on agent payment/partnership rather than quality metrics, potentially guiding users toward agents prioritizing Zillow revenue over client fit
Pricing Details
Zillow's core search and valuation features are completely free for consumers. Premium agent advertising and lead generation is where Zillow monetizes—agents pay for listing visibility and buyer leads, but consumers see no charges. Mortgage pre-approval and lending partner connections are free to initiate but actual loan products carry standard mortgage industry fees. No paywall exists for accessing listings, neighborhood data, or Zestimate valuations.
