Zillow vs. Realtor.com: What Scottsdale Homebuyers Should Know in 2026

If you’ve started your home search online, you’ve probably spent some time on Zillow, Redfin, or Realtor.com. These national platforms are household names, and they make browsing for homes feel as easy as scrolling through social media. But when you’re ready to get serious about finding your next home in a competitive market like Scottsdale, Arcadia, or Paradise Valley, are they really your best tool?

The truth is, while national portals are great for initial browsing and inspiration, buyers who rely on them exclusively often miss out on the most accurate, up-to-date listings. This can be a huge disadvantage, especially when homes are selling quickly.

In this guide, I’ll break down the differences between using national search portals and having direct access to the local Multiple Listing Service (MLS) through a Realtor like me. My goal is to give you the insider knowledge you need to make your home search in Arizona as smooth and successful as possible.

Zillow vs. Realtor.com vs. Local MLS: A Quick Comparison

When you’re looking for a home, you need information that is fast, accurate, and reliable. Let’s see how the big names stack up against a direct MLS feed from a local expert.

Feature	Zillow/Redfin	Realtor.com	Realtor Anne Sostman (Local MLS)
Listing Accuracy	Updated every 1–2 days; can show off-market homes	Updated daily from MLS feeds	Real-time feed direct from the Arizona MLS
Agent Connections	Multiple agents per listing (lead routing system)	One assigned agent	Direct access to your personal Realtor (Anne Sostman)
Local Market Insights	Nationwide data with limited local focus	Moderate local focus	Deep expertise in Scottsdale, Arcadia, & Paradise Valley
Hidden/Expired Listings	May show sold or pending homes as “active”	Sometimes includes outdated or expired listings	Active listings only — updated live
Buyer Support	Automated contact forms and chatbots	Automated contact forms	Personalized search help and expert negotiation

Why Listing Accuracy Matters in Fast-Moving Markets

In desirable areas like Scottsdale and Arcadia, the best homes can go under contract in a matter of days—sometimes even hours. This is where the delay in data from national portals becomes a real problem. Relying on a platform that only refreshes its listings once or twice a day means you could be falling in love with a home that is already sold or has a pending offer. It’s a frustrating experience I see buyers go through all the time.

My website, AMSRealtyAZ.com, is powered by the Arizona Regional MLS. This means it updates in real time, giving you access to the same live data that I use as a Realtor. You’ll see homes the instant they hit the market, get immediate notifications about price changes, and know right away when a property goes under contract.

Pro Tip: The MLS is the single source of truth for property status, pricing, and new listings in any given market. All national portals pull their information from this same feed, but often with significant delays.

The Buyer Experience: Local Expertise Makes the Difference

Have you ever clicked “Contact Agent” on Zillow or Realtor.com, only to be flooded with calls and emails from multiple agents? That’s because these platforms are primarily lead generation tools. They sell your contact information to agents who pay to be featured on a listing—who are not necessarily the listing agent or a local expert. This can create confusion and add unnecessary pressure to your home search.

When you search on AMSRealtyAZ.com, you’re connected directly with me. You get one dedicated professional who knows the Scottsdale and Paradise Valley markets inside and out. I personally help my clients by:

Setting up tailored property alerts based on their specific needs.
Providing insights into neighborhoods, schools, and local amenities.
Giving them access to off-market and “coming soon” listings before they appear on national sites.

This one-on-one relationship ensures you have a trusted advisor who is focused on your best interests, not just making a sale.

Beyond Listings: Real Support for Real Decisions

Buying a home is one of the biggest financial decisions you’ll ever make. It’s about more than just browsing photos online; it requires a deep understanding of market trends, neighborhood values, and strategic timing.

That’s where a local expert provides value that national websites simply can’t match. On AMSRealtyAZ.com and through working with me directly, you gain access to:

Local market reports and in-depth community guides.
Expert pricing insights based on real-time comparable sales, not a generic computer algorithm like Zillow’s “Zestimate.”
A trusted partner to help you navigate offers, negotiations, inspections, and closing.

I have spent years building my expertise in the Scottsdale area, and I love sharing that knowledge to help my clients make confident, informed decisions.

Find Your Next Home with Confidence

So, which tool is right for you? If you’re just starting your search and casually browsing for inspiration, Zillow, Redfin, and Realtor.com are perfectly fine. They offer a user-friendly way to explore what’s out there.

But if you’re serious about buying a home, especially in the competitive markets of Scottsdale, Paradise Valley, or Arcadia, direct MLS access is non-negotiable. It gives you the most reliable data, the most current listings, and the advantage of working with a local professional who is dedicated to your success.
