AI Fake Appraisers Inflate Real Estate Valuations for Loan Fraud: Forging Reports to Siphoning Excess Loans and Investments

Who Gets Targeted

Victims mainly fall into two categories: First, middle-aged and young office workers who are anxious to buy or replace real estate. They are often lured by 'zero down payment' and 'high appraisal for high loan' tactics, blindly trusting the AI appraisal reports provided by intermediaries to increase their loan amounts while ignoring subsequent monthly mortgage payments and legal risks. Second, private capital lenders, including micro-lending companies and private mortgage lenders, relax their due diligence upon seeing official-style appraisal reports, treating real estate valuations as risk control foundations, and ultimately losing everything because the actual value of the property is far below the loan amount.

骗局怎么运作

• Step 1: Black market syndicates mass-scrape real property information and real estate transaction data, training or fine-tuning generative AI models so they can mimic the report formats, seal styles, and wording of formal asset appraisal institutions, producing 'Real Estate Appraisal Reports' that are virtually indistinguishable from the real thing.
• Step 2: They target customers through real estate intermediaries, loan brokers, or social chat groups, claiming they can facilitate 'high appraisals for high loans' and 'zero down payment home purchases.' Exploiting homebuyers' financial distress, they charge 'appraisal fees' or 'service fees' ranging from several thousand to tens of thousands of yuan, promising that the appraised value will be at least 20% higher than the market price.
• Step 3: The AI automatically generates multiple sets of inflated appraisal reports, raising property valuations by 30% to 100%. The reports are attached with forged appraiser signatures, qualification numbers, and institutional filing numbers. Some syndicates even build counterfeit official websites for banks or private capital parties to verify online, achieving a high degree of authenticity.
• Step 4: They assist clients in applying for mortgage loans from banks or borrowing from private capital parties using the inflated appraisal values. Because the appraisal reports appear compliant, some institutions with lenient reviews conduct only formal audits before disbursing funds. The loan amount far exceeds the actual loanable value of the property, and the price difference is split among the syndicate and intermediaries.
• Step 5: After disbursement, the syndicate quickly loses contact or changes contact information. Homebuyers are left saddled with debt far exceeding the value of the property, and even after the property is auctioned following a default, the proceeds are insufficient to pay off the debt. Private capital lenders face non-performing loans due to insufficient collateral value, and in some cases, the mortgage registration itself involves forged materials, making rights protection extremely difficult.

红旗信号（看到这些快跑）

• 🚩 The appraisal institution listed in the appraisal report has no record of filing on the official website of the housing and urban-rural development department or the asset appraisal association, or its filing status is abnormal.
• 🚩 The appraiser's signature and practice registration information on the report do not match, or the qualification number format is incorrect and the corresponding personnel cannot be queried.
• 🚩 The appraised value is significantly higher than the recent average transaction price of similar properties in the same location by more than 30%, with no reasonable explanation.
• 🚩 Intermediaries or lenders urge signing as soon as possible, claiming that 'appraisal values have a validity period' or 'quotas are limited,' while refusing to provide the institution's phone number or on-site verification channels.
• 🚩 Requests to transfer 'appraisal fees' or 'expedited fees' to personal accounts or third-party companies rather than the public account of the appraisal institution, and failure to provide formal invoices.
• 🚩 Clauses regarding property appraisal values and loan-to-value ratios in loan contracts or borrowing agreements are vague, or deliberately evade details of default liabilities.

How to Protect Yourself

• ✅ Before taking out a loan, verify the filing qualifications of the appraisal institution and the appraiser's practice registration information one by one through the official website of the housing and urban-rural development department or the asset appraisal association. Any entity that cannot be queried must be regarded as invalid.
• ✅ Require the appraisal institution to issue a formal commission contract and confirm it by calling back through the institution's official landline. Avoid communicating solely via mobile phone numbers or WeChat, and ensure all fund transfers go through public corporate accounts while requesting invoices.
• ✅ Independently or entrust an independent third-party appraisal institution to re-evaluate the property, cross-checking it with the loan appraisal report. If the discrepancy exceeds 10%, terminate the transaction immediately.
• ✅ Maintain vigilance against promotions such as 'zero down payment' and 'high appraisal for high loan,' actively consult local financial regulatory authorities or bank personal loan departments regarding policy red lines, and do not blindly trust verbal promises from intermediaries.
