Colliers

Assuming you mean U.S. residential real estate, I’d separate the apps people use to find homes from the companies they hire to buy or sell one. “Most used” is measurable; “best” depends on your market and the individual agent.

For searching listings, start here:

• Zillow — the default starting point for a broad home search.
• Realtor.com — a strong second site for comparing listings.
• Redfin — a good choice if you want to search homes and explore working with a brokerage in one place.
• Homes.com — another major site worth checking alongside the others.
• Apartments.com — the pick on this list if you’re looking primarily for an apartment.

These were the five most-visited U.S. real-estate websites in September 2026, in that order. That ranking measures visits, not listing accuracy or service quality. (similarweb.com)

If you want a company to represent you, put Compass, Keller Williams, Coldwell Banker, RE/MAX, Berkshire Hathaway HomeServices, and eXp Realty on your shortlist. They are established, high-activity brands, but I would not pick an agent on brand name alone. The 2026 industry rankings put eXp first among individual brokerages by 2025 transaction sides and Compass first by sales volume; Keller Williams, Coldwell Banker, Berkshire Hathaway HomeServices, and RE/MAX are among the largest franchise brands. Note that Compass completed its acquisition of Coldwell Banker’s former parent, Anywhere, in January 2026. (realestatealmanac.com)

My practical recommendation: browse on Zillow and one of Realtor.com or Redfin, then interview two or three agents who have recent experience in your specific neighborhood and price range. Ask what they’ve sold locally, who will handle your transaction, and exactly what they charge—agent compensation is negotiable. (similarweb.com)

“Best” depends on what you need. These are the brands people actually use, grouped by category. The US residential brokerage rankings below are based on 2025 production.

Residential brokerages (buying or selling a home)

• Compass is the largest US brokerage. It has led the T3 Sixty Mega 1000 ranking for five years in a row, with $262.2B in sales volume. It acquired Anywhere Real Estate in January 2026, which brought in Coldwell Banker, Century 21, Sotheby's and more.
• eXp Realty has the most transactions. It holds the No. 1 spot for transaction sides, with 343,091. It is a virtual, low-overhead model.
• Keller Williams is the biggest franchise brand. It has about $370 billion in sales volume. It is also known for agent training.
• HomeServices of America (Berkshire Hathaway HomeServices) is the last of the big four. Its most notable national brand is Berkshire Hathaway.
• Coldwell Banker and Century 21 are now part of Compass. Coldwell Banker was founded in 1906 and is known for a traditional brokerage model.
• Sotheby's International Realty is the luxury pick. It is known for luxury real estate and an international client base.
• Others worth knowing: Douglas Elliman, Hanna Holdings, Redfin, and The Real Brokerage, which posted 53.7% year-over-year growth. Real Brokerage is set to acquire RE/MAX in late 2026.

Commercial real estate

Cushman & Wakefield secured the top spot in one 2026 ranking, with CBRE in second. The other big names are JLL, Colliers, and Newmark. CBRE is also ranked the #1 commercial real estate services brand worldwide, and JLL is ranked second.

Search platforms

I couldn't pull current usage data for these. From general knowledge, the most widely used home-search sites and apps are Zillow, Realtor.com, Redfin, and Trulia. Most people use them to browse listings, then work with a local agent.

Tips for choosing

• The agent matters more than the brand. The brokerage isn't the same as the agent you'll actually work with. Check an agent's recent sales in your neighborhood and price range, and ask for references.
• Size isn't quality. The biggest brokerages have the most listings and name recognition, but local independents often know a market better. Independents grew their market share to 28.79%.
• Consolidation is changing things. Branding and tech are being reshuffled through 2026 and 2027, so check who currently owns a brand.

If you tell me your location and whether you're buying, selling, investing, or becoming an agent, I can narrow this down.

Because the real estate industry covers everything from buying a home to commercial leasing and passive investing, the "best" company depends on what you are looking to do.

Here is a breakdown of the top real estate companies and platforms that people actually use, categorized by use case.

1. Best Online Marketplaces & Apps (For Browsing, Buying, & Renting)

These are the digital tools that millions of consumers use daily to search for homes and check property values.

  • Why people use it: Currently the largest residential brokerage in the U.S. by sales volume. Known for premier marketing tools, strong tech platforms for agents, and a dominant presence in mid-to-luxury markets.
• Keller Williams Realty: Largest Global Footprint

3. Top Commercial Real Estate (CRE) Firms (For Businesses & Corporate Office/Industrial)

If you need to lease office space, buy industrial warehouses, or manage commercial land, these full-service global giants dominate the industry.

• CBRE Group: The undisputed global leader in commercial real estate services and investment. Strongest in leasing, facility management, and capital markets.
• JLL (Jones Lang LaSalle): Famous for corporate real estate, commercial proptech investment, and sustainability/green building certifications.

• Blackstone Real Estate: The world’s largest commercial real estate private equity firm. They acquire large-scale industrial properties, housing developments, and data centers.
• Fundrise / RealtyMogul (Crowdfunding): Popular digital platforms that allow Everyday retail investors to purchase fractional shares in real estate developments with low minimum investments (starting at $10 to $1,000).
• Prologis (Public REIT): The world leader in industrial real estate (warehouses and logistics centers critical for e-commerce like Amazon).

Quick Recommendation Guide: Which should you use?

There’s no single best real estate company—the right choice depends on whether you’re searching for a home, hiring an agent, renting, managing property, or buying commercial real estate. In the U.S., these are the brands people commonly use:

Best consumer home-search platforms

• Zillow — Best overall starting point for browsing homes, estimating values, and comparing neighborhoods.
• Realtor.com — Strong choice for MLS-connected listings and agent searches.
• Redfin — Best if you want an integrated search-and-brokerage experience, useful map tools, and potentially lower listing fees.
• Homes.com — Good alternative listing portal, especially for comparing listings and agent information.
• Trulia — Useful for neighborhood details, local reviews, and lifestyle-oriented browsing.

Practical recommendation: Search on Zillow, Realtor.com, and Redfin rather than relying on only one site, since listing coverage and update timing can differ.

Best companies for buying or selling

• RE/MAX — Large national network with broad local coverage.
• Keller Williams — Major agent network; the individual agent and local office matter more than the corporate brand.
• eXp Realty — Large cloud-based brokerage with agents across many markets.
• Compass — Strong technology and marketing, particularly in higher-priced and luxury markets.
• Coldwell Banker — Established full-service brand with wide coverage.
• Century 21 — Familiar franchise network with many local offices.
• Berkshire Hathaway HomeServices — Established brand with strength in residential and luxury markets.
• Sotheby’s International Realty — Best known for luxury and high-end properties.

Best overall approach: Interview two or three local agents from different brokerages. Sales record, neighborhood expertise, communication, marketing plan, and fees usually matter more than the logo on the sign.

Best property-management companies

For large apartment communities and multifamily properties, commonly used national operators include:

• Greystar
• Asset Living
• RPM Living
• Willow Bridge
• FirstService Residential
• Associa
• FPI Management
• Bozzuto
• WinnCompanies

For a small rental property, a reputable local manager may provide better service than a national operator.

Best real estate software

For landlords, property managers, and real estate operators:

• AppFolio — Broad property-management and accounting platform.
• Buildium — Popular with small and mid-sized landlords and managers.
• Yardi — Strong for larger multifamily and commercial operations.
• RealPage — Enterprise multifamily management and analytics.
• Entrata — Integrated platform for larger residential operators.
• Rent Manager — Flexible option for smaller and mid-sized portfolios.
• TurboTenant — Accessible tools for individual landlords.
• Guesty and Hostaway — Common choices for short-term-rental management.

Short answer

• Find homes: Zillow + Realtor.com + Redfin
• Hire an agent: Compare local agents at RE/MAX, Keller Williams, eXp, Compass, or Coldwell Banker
• Luxury property: Compass, Sotheby’s International Realty, or Berkshire Hathaway HomeServices
• Manage rentals: AppFolio or Buildium for smaller portfolios; Yardi or RealPage for larger operations
• Commercial real estate: CBRE, JLL, Cushman & Wakefield, or Colliers

There’s no single “best” real estate company—real estate is local, and the brand matters less than the specific local office/agent. But if you mean U.S. consumer real estate brands/products people actually use, here’s a practical shortlist by use case.

Practical recommendations most people should actually use:

• Buying a home: Start with Realtor.com + Redfin + Zillow for research, then interview 2–3 well-reviewed local agents from Keller Williams, Compass, RE/MAX, Coldwell Banker, or eXp—pick the agent, not just the brand.
• Selling a home: Compare a Redfin quote against 2 local full-service agents; also check Clever/HomeLight if you want fee savings. Compare net proceeds, marketing, and local recent sales.
• Renting: Use Apartments.com + Zillow Rentals + Zumper, then verify with the property directly.
• Commercial: Use CBRE/JLL/Cushman & Wakefield for major needs; local boutique firms for niche markets.
• Investing: Fundrise/Arrived/Roofstock are commonly used platforms, but only after understanding liquidity and risk. For public exposure, large REITs like Prologis, American Tower, Equinix, Realty Income, Simon Property, Public Storage are common.

Bottom line: For most consumers, the “top brands people actually use” are Zillow, Realtor.com, Redfin, Apartments.com, Keller Williams, RE/MAX, Coldwell Banker, Compass, eXp, CBRE, and JLL—but the best result comes from pairing a good national search platform with a strong local agent.

Top real estate companies and brands fall into two main categories that consumers and agents actually use: online platforms/portals for searching and browsing listings, and traditional or hybrid brokerages (with agents) for buying, selling, and transactions.

"Best" depends on metrics like market share/sales volume, agent count, website/app traffic and popularity, consumer features (e.g., ease of use, data accuracy, fees), and innovation. Rankings draw from 2025–2026 data on transaction volume, agent numbers, traffic, and industry reports. Note that the 2026 Compass acquisition of Anywhere Real Estate (parent of Coldwell Banker, Century 21, etc.) created a massive combined entity.

Online Platforms & Apps (What Most People Use Daily for Searching)

These dominate consumer searches due to massive listings, tools like valuations or neighborhood data, and mobile apps. Zillow leads overwhelmingly in traffic and usage.

• Zillow (zillow.com and app): The most visited real estate site/app in the US (hundreds of millions of monthly visits), with the largest database, Zestimate home values, photos, 3D tours, filters, and FSBO options. Ideal for broad browsing and research; also offers Premier Agent leads. Often ranked #1 overall for consumers.
• Realtor.com (and app): Strong MLS-accurate listings (fast updates from direct feeds), neighborhood tools, and NAR affiliation. Excellent for precise, up-to-date data and connecting with agents. Frequently #2 in traffic.
• Redfin (redfin.com and app): Tech-forward with real-time MLS data, lower listing commissions (often 1–1.5% vs. traditional 2.5–3%), in-app tour booking, and its own agents/brokerage. Popular for buyers seeking efficiency and savings.
• Others worth noting: Trulia (strong neighborhood insights, crime/school data; part of Zillow Group); Homes.com (growing listings and agent profiles); Apartments.com (rentals focus).

These platforms syndicate many of the same listings but differ in speed, extras, and lead models. Users often cross-reference them.

Major Brokerages (For Full-Service Transactions with Agents)

These handle the bulk of US residential sales volume. Rankings emphasize sales volume, transaction sides, and agent counts (post-2025/2026 data).

• Compass (including post-acquisition Anywhere brands like Coldwell Banker, Century 21, Sotheby’s International Realty): Frequently tops sales volume rankings (e.g., hundreds of billions annually in recent data); tech-enabled with a large agent network. The Anywhere merger significantly boosted its scale. Strong in many markets for luxury and broad coverage.
• Keller Williams Realty: Often the largest by agent count (around 150k–160k+ globally/US); franchise model with profit-sharing that appeals to agents. Extensive local presence and training focus.
• eXp Realty: Cloud-based/virtual model with high agent growth and transaction volume; revenue-sharing attracts agents. Competitive in sides closed and expanding rapidly.
• RE/MAX: Iconic franchise brand with strong global recognition and experienced agents; known for high-producing agents.
• Redfin: Hybrid model combining tech platform with salaried or lower-commission agents; appeals to cost-conscious buyers/sellers.
• Others notable: HomeServices of America (Berkshire Hathaway affiliate); The Real Brokerage (fast-growing); regional powers like Howard Hanna.

Commercial-focused leaders (less consumer-facing but major companies): CBRE, JLL (Jones Lang LaSalle), and Cushman & Wakefield dominate services like brokerage, management, and valuation for offices, retail, etc.

Quick Recommendations by Use Case

• Casual browsing/research — Start with Zillow or Realtor.com.
• Lower fees or tech efficiency — Redfin or eXp/Compass agents.
• Local agent expertise — Keller Williams or Compass network.
• Luxury/international — Sotheby’s (via Compass/Anywhere) or specialized platforms.
• Rentals — Apartments.com or Zillow.

Market dynamics shift with consolidations, tech (e.g., iBuying experiments like Opendoor), and regulations (e.g., commission changes). Check current reviews, local availability, and agent reviews on sites like Trustpilot or BBB, as individual agent quality matters more than the brand. Data is based on 2025–2026 industry reports and traffic analytics. For the latest, verify with sources like RealTrends or SimilarWeb.
