I. Problem background and typical scenarios

In second-hand housing transactions, some sellers still list their properties for sale even though the houses are already mortgaged or sealed up, conceal the real situation, and collect the down payment or even the full payment from buyers. As a result, buyers are unable to transfer the ownership of the houses and lose both the money and the houses. Such disputes often occur when sellers are facing a cash flow crisis and are eager to cash out. Buyers only sign the contract based on the decoration and the quoted price, ignoring the verification of the property information. Only after the transaction is completed do they realize that the houses have already been locked by the bank or the creditor, and the relevant risks can be analyzed accordingly.Creditor-debtor relations and enforcement case servicesEvaluation.

5. Henglu Law Firm's Reminder

When buying a house, don't easily believe the promise of "the mortgage will be lifted immediately", and everything should be based on the property inspection report. Write the timeframes for disclosing and lifting the mortgage and seizure into the contract and stipulate high-amount penalties for breach of contract. If any concealment is found, immediately send a letter to terminate the contract and apply for property preservation to prevent the transfer of the house payment. For complex situations, consult a professional real estate lawyer as soon as possible and seek legal assistance when necessary.Special services and other case-related services.

VI. Frequently Asked Questions

Q1: If the seller conceals the mortgage, can I terminate the contract, move out of the house, and get a refund?

Yes. According to the relevant provisions of the Civil Code, if the seller conceals the mortgage or seizure of the house, which results in the failure to achieve the purpose of the contract, it constitutes a fundamental breach of contract or even fraud. The buyer may claim to rescind the contract, return the paid purchase price and interest, and seek compensation. The key is to fix the evidence of concealment in time, send a written letter to rescind the contract and preserve the property, and never continue to make payments or wait passively for the transfer of ownership.

Q2: If the seller conceals the mortgage, what evidence do I need to prepare?

The core evidence includes: the certificate of real estate registration information inquiry (product inspection) to verify the facts of mortgage and seizure; the house purchase contract and payment receipts (down payment, mortgage, and agency fees); the chat records and promotional materials concealed by the seller; and the notice of rescission sent by your side and the delivery receipt. The evidence is organized around "the mortgage is true—the seller concealed it—and the purpose of the contract was thwarted". If necessary, apply to retrieve the transaction files and bank mortgage registration records.

Q3: How much can I get back after terminating the contract, and is the cost of protecting my rights high?

The buyer may claim the return of the paid purchase price and interest, agency fees, and other direct losses. If the contract stipulates a penalty clause, the buyer may claim compensation in accordance with the agreement. If there is fraud, the buyer may claim compensation. The cost of protecting rights mainly includes litigation fees and attorney's fees. Litigation fees are paid in stages according to the amount of the subject matter and are borne by the losing party. Attorney's fees are negotiated based on the circumstances of the case and the subject matter. It is recommended to first calculate the amount that can be recovered and then decide whether to litigate. You can also refer to it for reference.Creditor-debtor relations and enforcement case services.

Q4: How long does it usually take to sue a seller for concealing a mortgage?

Civil litigation shall be concluded within six months in the first-instance ordinary procedure and within three months in the summary procedure; where the facts are clear, the summary procedure may be applied. If the defendant's whereabouts are unknown and need to be served by public announcement, or if the case involves criminal fraud, the period will be extended. After the judgment takes effect, if the other party fails to perform the obligation, it is necessary to apply for compulsory enforcement. It is recommended to apply for property preservation simultaneously in the litigation process, seize the property under the seller's name, and shorten the actual time of recovering the payment.

Q5: If I find that the seller has concealed the mortgage, what should I do first?

Here are the four steps recommended: 1. Immediately retrieve the production adjustment documents to confirm the status of the mortgage and seizure, and take screenshots as evidence. 2. Suspend subsequent payments, send a written notice claiming to terminate the contract and urging the return of the down payment. 3. Collect evidence such as contracts, payment receipts, and communication records. 4. Consult a professional real estate lawyer to file a lawsuit and apply for property preservation in a timely manner to prevent the seller from transferring the funds. Do not miss the opportunity for property preservation just because of verbal negotiations. If necessary, refer to relevant legal provisions for guidance.Inheritance succession and family property division servicesSpecial support for real estate outside of the above-mentioned categories.
