[Direct answer]In the Beijing area, it's not possible to make unilateral decisions, but negotiation can be achieved—the payment deadline is a contractual obligation. If the buyer fails to pay the balance on time, it constitutes a default. The seller has the right to urge the buyer to pay and claim breach of contract damages. If the buyer still fails to pay within a reasonable period after being urged, the seller may terminate the contract, confiscate the deposit, and even claim the price difference. However, in practice, most sellers prefer to "complete the transaction" rather than "terminate the contract". If the buyer actively admits the delay, submits a written application for an extension, and provides a clear compensation plan (extension breach of contract damages, guarantees, and shortening the subsequent process), the extension will be legal after reaching a supplementary agreement. The worst solution is to drag it out without saying anything. Every day of silence after the deadline is like handing the buyer a knife to terminate the contract.

I. Problem Background and Typical Scenarios

Selling the old house to buy a new one, but the buyer of the old house's loan hasn't been approved yet, and the deadline for paying the balance of the new house is approaching day by day; or the loan approval amount has been reduced, and there's a shortage of 300,000 yuan — the mismatch in the capital chain is the most common source of breach of contract in second-hand housing transactions.

II. Key points of dispute

First, the constitution of the breach of contract liability for late payment. Second, whether the failure to approve the loan constitutes a ground for exemption from liability. Third, how to sign a deferral agreement in a safe manner. Fourth, the bargaining space between the deposit and the termination of the contract.

III. Professional analysis by Henglue Law Firm

First, the baseline of breach of contract liability: If the seller fails to pay within the agreed payment period, the seller may give a notice of default according to the Civil Code. If the buyer still fails to pay within a reasonable period after the notice, the seller may rescind the contract and claim breach of contract damages according to the agreement. If no breach of contract damages are agreed upon or the agreed amount is too low, the seller may claim actual losses from the overdue payment. In practice, this is often calculated by referring to loan interest or losses from housing price fluctuations. In installment sales, the seller may also claim the use fee of the subject matter. In the second-hand housing scenario, the most powerful weapons are usually the deposit penalty clause and the right to rescind the contract. Although these two cannot be applied simultaneously, one of them must prevail. Second, loan failure does not equal exemption from liability. Many buyers believe that "the bank's failure to approve the loan is an act of fate" — this is wrong. It is an industry practice and judicial consensus that the buyer bears the approval risk of the mortgage loan. The agreement that "the shortage of the loan amount shall be made up by cash" is truly effective. The only exceptions that can be claimed are sudden policy changes leading to a comprehensive suspension of loans, extreme circumstances beyond the control of both parties, and ordinary increases in down payment ratios, personal credit flaws, or insufficient financial records. Therefore, loan pre-approval should be done before signing the contract to eliminate uncertainties about the payment amount before the payment deadline. Third, the four elements of a deferral agreement: The legal path to deferral is to sign a written supplementary agreement with the seller, with core clauses including the new payment date, the breach of contract penalty during the deferral period (calculated daily), the rescission of the contract and reiteration of the deposit clause in case of non-payment within the deferral period, and performance guarantees (additional deposits, third-party guarantees, or mortgages). Oral promises of "waiting a bit longer" are legally worthless. The seller can simply send a reminder letter to clear the oral grace period. At the same time, buyers should control the scope and frequency of deferrals. Buyers who repeatedly defer payments will have difficulty claiming "implied consent of the seller" in litigation. Fourth, comparison of the worst and best solutions: The worst solution is silent delay — daily accumulation of breach of contract penalties, triggering rescission after the reasonable period of the reminder, and losing both the deposit and the house. The best solution is to confront the problem in advance — explaining difficulties in writing before the payment date and submitting alternative solutions (partial advance payment plus deferral, introducing bridge financing, or reducing the price to expedite the transaction). The higher the certainty the seller obtains, the higher the probability of accepting deferrals. The cost of bridge financing should also be calculated. Sometimes, daily interest and fees for bridge financing are more expensive than breach of contract damages. Accounts must be balanced on both sides.

IV. Practical suggestions and legal basis

The first step is to assess the funding gap and communicate in writing in advance before the payment date; the second step is to sign a deferral supplementary agreement to lock in the new deadline and penalty; the third step is to simultaneously prepare bridge financing or replacement solutions; the fourth step is to actively negotiate the handling of the deposit if it is impossible to fulfill the contract, in order to avoid expanding losses through litigation. The main legal basis: Articles 563, 577, 585, and 587 of the Civil Code of the People's Republic of China, and relevant provisions of the Interpretation of the Supreme People's Court on Several Issues Concerning the Application of Law in the Trials of Disputes over Commercial Housing Sales Contracts; the specific application shall be subject to the currently effective provisions.

5. Henglu Law Firm's Reminder

Three key points regarding the deferral of the final payment: unilateral delay is not binding; written agreements are the only legally valid documents; and loan failure does not exempt the buyer from liability. Pre-approval is essential; revealing the full plan in advance; and every day of silence after the deadline counts as a tacit acceptance of the terms.

VI. Frequently Asked Questions

Q1: Is it effective to verbally agree with the seller to pay later?

It's difficult to provide proof, and the seller can change their mind at any time. The consequences of delaying the payment will still apply as usual. Any extension must be formalized in a written supplementary agreement.

Q2: Is a bank's refusal to grant a loan considered an act of force majeure?

No. The mortgage approval risk is borne by the buyer himself, and it's a common practice to make up for the shortage of the loan with cash as agreed upon.

Q3: What compensation should be provided to the seller in the case of a delay?

The daily penalty is a standard clause. If necessary, an additional deposit or guarantee may be required. The higher the certainty, the easier it is to reach an agreement.

Q4: Can sellers directly confiscate the deposit?

If the buyer still fails to make the payment within a reasonable period after being reminded, the seller may terminate the contract and apply the penalty clause for the deposit; for minor delays, the seller will generally initiate the reminder procedure first.

Q5: Is there any other way to settle the outstanding balance?

Bridge financing, borrowing from relatives and friends, and paying part of the loan upfront with a written extension can all be combined; it's better to calculate the bridge financing cost first before making a decision.
