In recent years, the adoption of AI (artificial intelligence) technology in the real estate industry has been advancing rapidly. Particularly in the field of real estate appraisal, AI systems capable of instantly analyzing vast amounts of past transaction data and market trends to calculate highly accurate appraisal prices are appearing one after another. When confronted with such technological evolution, quite a few people wonder: "Will human agents eventually become unnecessary?"
However, to state the conclusion first: no matter how much AI evolves, the value of human agents in real estate transactions will never be lost. On the contrary, I am convinced that precisely in an era when AI is becoming widespread, the value that only humans can provide becomes even more important.
In this article, INA&Associates Co., Ltd. explains, along with specialized real estate knowledge, the workings and advantages and disadvantages of AI appraisal, as well as the role of human agents that will be required in the coming era. We hope you will read this whether you are considering selling or purchasing real estate, or thinking about a career in the real estate industry.
What Is AI Real Estate Appraisal? Its Mechanism and Features
AI real estate appraisal is a mechanism in which a machine learning algorithm analyzes big data — including vast past transaction cases, surrounding land price trends, and property specifications (building age, exclusive area, distance from the nearest station, floor number, etc.) — and calculates the statistically most reasonable price. Currently, more than 20 AI appraisal services are offered in Japan, and an environment where even general consumers can easily use them is in place.
AI appraisal's greatest strength lies in its overwhelming speed and objectivity. When humans manually collect data and make comparative studies, it inevitably takes several days to about a week. With AI, however, results can be derived in seconds to minutes. Additionally, bias such as "intentionally presenting a high appraisal value in order to close a deal" — which human agents are prone to — is completely eliminated, enabling an objective price based on pure data to be known.
Furthermore, AI appraisal resolves the problem of "person-dependence" — where the appraisal value changes significantly depending on the representative. In conventional real estate appraisal, differences of several million yen could arise for the same property depending on the experience and knowledge of the sales agent. AI corrects this disparity and realizes an environment where anyone can obtain a price evaluated by the same standards.
AI Appraisal Accuracy: How Far Can It Be Trusted?
There are significant differences in AI appraisal accuracy depending on the type of property. For condominiums (apartment buildings) with abundant transaction cases, AI appraisal prices often fall within approximately 80–90% of actual transaction prices in many cases, reaching practically useful accuracy. On the other hand, for detached houses and land, accuracy tends to decrease due to high individuality and fewer transaction cases.
Additionally, since AI appraisal uses "past data" as a learning foundation, it may be slow to respond to sudden market fluctuations or region-specific circumstances (such as announcements of large development plans or changes in natural disaster risk). While accuracy is high in urban areas with abundant data, there are cases where reliability decreases in suburban and rural areas with fewer available transaction cases.
Comparison of AI Appraisal and Appraisal by Human Agents
AI appraisal and appraisal by human agents each have different strengths and weaknesses. The following table organizes the main comparison points.
| Comparison Item | AI Appraisal | Appraisal by Human Agent |
|---|---|---|
| Speed | Instantly calculated in seconds to minutes | Several days to about a week |
| Objectivity/Fairness | Very high as it is data-based | Room for the agent's experience and intent to intervene |
| Qualitative Evaluation | Difficult to reflect individual factors such as interior condition, views, and community | On-site inspection enables evaluation of value not appearing in data |
| Response to Market Changes | Weak against sudden changes due to dependence on past data | Flexible response possible based on latest market conditions and individual customer circumstances |
| Emotional Support | Not possible | Can empathize with customer anxiety and build trust relationships |
| Negotiation and Adjustment | Not possible | Interest adjustment and price negotiation between seller and buyer possible |
As this table clearly shows, AI appraisal and appraisal by human agents should not be discussed in terms of a binary opposition of "which is superior." Each plays a different role, and the most ideal approach is a hybrid approach combining AI's objective data with human qualitative evaluation.
AI Appraisal's Limitations: What Is "Value That Cannot Be Digitized"?
The value of real estate is not determined by mere strings of numbers. For example, the condition of an interior carefully used over many years, the renovation history an owner painstakingly considered, a wonderful view from the window, or a good community with nearby residents — these elements are currently difficult for AI technology to accurately reflect in prices.
Real estate transactions also have backgrounds deeply tied to individual life planning — "why sell now," "what to do about the next residence," "what are the family's future plans." AI cannot read such context. On the other hand, experienced agents can carefully understand these backgrounds through dialogue with customers and provide comprehensive advice beyond mere price presentation.
Furthermore, in a survey conducted by the Real Estate Information Site Business Operators Council (RSC), the top of what users seek from real estate companies was "careful and sincere service." Second was "provision of accurate property information" and third was "prompt response to inquiries." These results show that what customers seek from real estate companies is not merely speed of information processing but a human relationship founded on "trust".
From "Information Provider" to "Decision-Making Companion": How Human Agents' Roles Are Changing
Now that AI has begun handling information gathering, property matching, initial responses, and document creation assistance, the roles required of human agents have changed significantly. In the past, real estate agents' main role was "information provider leveraging information asymmetry." However, with the spread of the internet and AI, general consumers can now easily access property information and market data.
In this change, what is required for human agents to survive is functioning as a "decision-making companion". Knowing how to read numbers, explaining the meaning of hazard maps, making customers aware of the possibility of neighbor disputes, and organizing property priorities against 5-year and 10-year life plans. This "decision-making companionship" cannot be replaced by efficiency improvements in information processing.
In fact, with AI shouldering information gathering and initial appraisal work, the time available for agents to focus on this essential work is arguably increasing. Technological evolution is giving human agents the opportunity to evolve from "information processing handlers" to "providers of human value."
Three Conditions Required of Real Estate Agents in the AI Era
So specifically, what kind of abilities would an agent with high value even in the AI era have? I believe the following three conditions are particularly important.
First, information literacy to use AI as a "tool." Agents who can view AI not as a threat but actively utilize it as a tool to strengthen their own operations have a large competitive advantage. The ability to accurately interpret AI appraisal results and clearly explain to customers the meaning and limitations of those numbers is an essential skill for the coming era.
Second, dialogue ability to move customers on both emotional and logical fronts. Because real estate transactions are high-value transactions with a strong life impact, deep-rooted trust in direct human interaction remains. Agents who can grasp the emotional needs behind customers' words and make optimal proposals combining logical grounds with emotional empathy are irreplaceable by AI.
Third, accumulation of "local knowledge" beyond property information. What AI struggles with is region-specific information that doesn't appear in data. Information such as the potential of a specific area, the characteristics of the local community, municipal development plans, and school district reputation is knowledge that only agents who have been active in that area for many years can possess. This "local knowledge" is highly valuable information for customers and is a clear differentiating factor from AI.
The Fusion of Technology and Humans: INA&Associates Co., Ltd.'s Approach
We at INA&Associates Co., Ltd., as a "tech-driven talent investment company," place the fusion of technology utilization and human imagination and creativity at the core of our corporate philosophy. Using AI-calculated objective data as a "powerful weapon," while deeply caring for each customer's life and jointly considering optimal choices.

Our company actively utilizes AI for market data analysis and initial price calculation, improving operational efficiency. The time created thereby is devoted to careful dialogue with customers and more detailed support, continuously improving service quality. Based on our belief that "talent" is a company's most important asset, we constantly continue pursuing "value that only humans can provide." Real estate transactions are not merely property buying and selling. They are a deeply human endeavor of supporting customers at important turning points in their lives. I am convinced that no matter how much AI evolves, that essence will not change.

Frequently Asked Questions
Q1. Does the AI appraisal price directly become the sale price?
AI appraisal prices are merely "guidelines" based on past data and do not directly become sale prices. The actual sale price is determined with the human agent making the final judgment, comprehensively taking into account the interior condition, latest market trends, selling timing, and buyer needs. AI appraisal should be used only as a "starting point," and subsequent detailed appraisal and negotiation are recommended to be entrusted to specialists.
Q2. Which should I trust — AI appraisal or human appraisal?
Rather than trusting one or the other, we recommend utilizing both in combination. By first using AI appraisal to understand objective market conditions, then adding on-site inspection and qualitative evaluation by an experienced agent, a more precise and convincing appraisal price can be derived. If there is a large discrepancy between AI appraisal results and human appraisal results, it is important to have the agent carefully explain the reason.
Q3. Will real estate agents' jobs disappear in the future due to AI proliferation?
We believe real estate agents' jobs will not disappear. AI streamlines routine tasks such as information gathering and initial appraisal, but tasks such as building trust relationships with customers, responding to complex emotional needs, negotiation and adjustment work, and accompanying important life decisions remain areas that humans should continue to handle. Rather, it can be said that by utilizing AI to be freed from routine tasks, an environment for concentrating on more essential customer service is being formed.
Q4. Are there any points for identifying a trustworthy real estate agent?
There are several points for identifying a trustworthy real estate agent. First, whether they explain not only merits but also demerits and risks without hiding anything is important. Next, whether they respond promptly and sincerely to customers' questions, and whether they can provide advice looking ahead to future life plans rather than merely proposing properties, also becomes a judgment criterion. Also, agents who actively utilize data such as AI appraisals while carefully explaining the meaning and limitations of those numbers can be said to have high expertise and integrity.
