Can AI Get Your Home's Value Wrong?

Artificial intelligence is changing how people research real estate. Not to mention buy and sell. From analyzing market trends to estimating property values, AI can deliver information within seconds. But how accurate are those estimates when millions of dollars are involved? In Scottsdale, Paradise Valley, and throughout Greater Phoenix, the answer often depends on the quality of the information available and the characteristics of the property itself.

Quick Points

• AI valuations depend on accurate, accessible property data
• Unique luxury features can significantly influence prices
• A $50 million transaction nearly collapsed over AI advice
• HomeLight research highlights seller pricing challenges
• WLH combines artificial intelligence with real estate expertise

What HomeLight's Research Reveals

A nationwide survey from HomeLight highlights the importance of accurate pricing and the challenges associated with online property information.

The company's Fall 2026 Top Agent Insights report surveyed 715 real estate agents about market conditions and seller expectations.

Two findings stand out:

• 80% emphasized the importance of accurate initial pricing
• 64% identified seller misunderstandings about property values based on AI and online information

These results reflect surveyed agents' experiences, not a measured error rate for AI valuations. Nevertheless, they demonstrate why automated estimates deserve careful consideration.

AI can analyze enormous amounts of information, but it may not have access to every detail that influences a home's actual market value.

When AI Tells Users What They Want To Hear

Artificial intelligence systems are designed to be helpful, but that can sometimes create an unexpected problem. Researchers have documented a behavior known as AI sycophancy, where a chatbot becomes overly agreeable, reinforces a user's assumptions, or provides answers that favor what the person wants to hear. AI companies have made improvements to address this behavior, but the concern hasn't disappeared.

This tendency can appear in several ways:

• Agreeing with unsupported assumptions
• Reinforcing unrealistic expectations
• Giving different answers to similar questions
• Prioritizing agreement over factual accuracy
• Encouraging excessive trust in AI responses

Psychologists and researchers have also examined the broader effects of AI sycophancy, including how repeated validation can influence decision-making, personal relationships, and emotional dependence. The concern extends far beyond real estate. In a property transaction, one seller might receive an AI assessment suggesting their home is underpriced, while a buyer receives an assessment suggesting the same property is overpriced. Different questions and incomplete context can contribute to these conflicting conclusions.

A $50 Million Deal Nearly Fell Apart Over AI

One remarkable example involves New York real estate broker Ryan Serhant.

During a 2026 appearance at Fortune's Brainstorm Tech conference, Serhant described a $50 million penthouse transaction that nearly collapsed after the buyer and seller consulted ChatGPT.

According to his account, the buyer received an assessment suggesting the property was overpriced. When the seller questioned whether the agreed price was too low, the AI offered a conflicting assessment.

The disagreement nearly derailed the transaction, which Serhant said ultimately closed after additional market context helped resolve the situation.

Several issues were involved:

• Limited comparable properties
• Missing transaction context
• Conflicting AI-generated assessments
• Different questions producing different conclusions

The lesson? A confident AI response isn't necessarily an accurate property valuation. The information provided, questions asked, and available market data all matter.

Why Luxury Properties Are Especially Challenging

Consider seperate custom estates in Paradise Valley. Both measure 7,000 square feet and occupy approximately one-acre homesites.

One offers unobstructed Camelback Mountain views. The other has limited mountain visibility.

That difference alone could substantially influence market value, depending on comparable transactions and buyer demand.

Other factors can complicate automated valuations:

• Architectural quality and custom finishes
• Mountain views and lot orientation
• Privacy and surrounding properties
• Renovations and structural condition
• Usable land and redevelopment potential
• Recent comparable sales and buyer activity

In some Paradise Valley neighborhoods, older residences are purchased primarily for their land. Developers may demolish existing structures and construct new estates through infill redevelopment.

A property's price per square foot rarely tells the entire story.

Online valuation systems and AI assistants may not have complete information about these circumstances. Even when property details are available, determining their contribution to market value requires reliable comparisons and careful interpretation.

AI Is Improving, But Data Still Matters

Artificial intelligence continues advancing rapidly. More sophisticated models and improved access to information are creating opportunities for better real estate research.

These technologies can help with:

• Reviewing market trends
• Analyzing comparable transactions
• Organizing property information
• Identifying inconsistencies in available data
• Researching neighborhood activity

However, even sophisticated AI systems can produce unreliable conclusions when information is incomplete, outdated, or incorrectly interpreted.

Better technology doesn't automatically mean better valuations. Better data matters just as much.

An automated valuation, professional appraisal, comparative market analysis, and response from a generative AI assistant are also different things. Each involves distinct methods and limitations.

How WLH AI Approaches Technology

At Williams Luxury Homes, our in-house artificial intelligence division WLH AI reflects our commitment to following advances in artificial intelligence and identifying practical applications for real estate.

Technology changes quickly. New models, research tools, and capabilities can emerge faster than businesses can fully evaluate them.

Our approach emphasizes:

• Staying informed about emerging AI capabilities
• Reviewing information for accuracy
• Recognizing limitations in available property data
• Combining technology with local market knowledge
• Maintaining professional oversight

We believe artificial intelligence will become increasingly valuable throughout the real estate industry.

We also believe that experienced real estate professionals remain an important part of evaluating unique properties and making informed decisions.

The Future Of AI In Real Estate

AI is becoming an increasingly useful resource for buyers, sellers, and real estate professionals. As its capabilities improve, it may provide more detailed information and increasingly sophisticated property analysis.

But real estate remains highly specific to the individual property.

A remarkable mountain view, exceptional construction, or valuable redevelopment opportunity can influence pricing in ways that automated systems may struggle to evaluate accurately.

For buyers and sellers, the smartest approach is to use AI as a research tool while verifying important information through qualified professionals and reliable market data.

The future isn't about choosing between artificial intelligence and real estate expertise. It's about using them together to make better-informed decisions.

That's the approach we believe makes sense for Scottsdale, Paradise Valley, and the Greater Phoenix luxury real estate market.
