You sign a sales agreement and the notary asks you what interest rate to include in the financing clause. An improperly calibrated rate in the sales agreement can invalidate the loan contingency, expose you to the loss of the deposit, or block the transaction for weeks. Understanding how to indicate this interest rate protects both the buyer and the seller.
Shared responsibility between notary, real estate agent, and broker regarding the rate in the agreement
Before even discussing numbers, let’s ask a rarely addressed question: who, concretely, decides on the rate included in the agreement? In theory, it is the buyer who provides the characteristics of their financing. In practice, several parties influence this choice, and none bear sole responsibility in case of error.
The notary drafts the deed and checks the legal consistency of the loan contingency. They ensure that the maximum rate mentioned complies with legal standards. The real estate agent often pushes to set a rate close to the market to secure the sale. The broker, when involved, provides an estimate of the rate that the buyer can actually obtain.
The problem arises when these three parties do not communicate with each other. A real estate agent who sets a rate too low to reassure the seller can trap the buyer. A broker who promises a rate without a safety margin exposes their client to a loan refusal not covered by the loan contingency. To better understand this topic, you can consult the recommended practices on Alpha Immobilier that detail the negotiations among these parties.
Each professional involved should validate the rate before signing. The buyer has every interest in requiring a written exchange between their broker (or bank) and the deed drafter before committing.
Loan contingency: what the maximum interest rate legally changes
The loan contingency for a mortgage is not a mere formality. It is a legal protection for the buyer, and its content is closely monitored by the courts. The financing characteristics included in the agreement (amount, duration, maximum interest rate) are not just indications. They are strict conditions that loan applications must comply with.
Article L313-40 of the Consumer Code imposes a minimum period of 45 days to obtain the loan. If the maximum rate is poorly drafted or absent, the protection may become unenforceable against the buyer. In case of bank refusal, the buyer may not recover their deposit.
The trap of a rate that is too low in the agreement
Let’s take a simple example. You enter a maximum rate very close to the market rates at the time of signing. Two weeks later, rates rise slightly. Your bank offers you financing at a rate higher than that in the agreement. You accept this loan, thinking that the loan contingency protects you.
It does not protect you. A loan obtained at a rate higher than the maximum provided does not comply with the terms of the agreement. Case law confirms this: loan applications must exactly match the parameters of the pre-contract.
The trap of a rate that is too high
Setting a very high rate to leave some margin can also pose problems. The seller may refuse an agreement with an unreasonable rate, as it signals a weak file.
Moreover, the recommendations from the HCSF cap the debt ratio at 35% of net income. An inflated rate can generate monthly payments incompatible with this cap, leading to a loan refusal that the loan contingency will not cover if the file has not been prepared within the exact parameters of the agreement.
What rate to include in a sales agreement
You understand the risks of both extremes. The practical question remains: how to set the right rate? The method relies on three concrete benchmarks.
- Ask your bank or broker for a feasibility certificate mentioning the estimated rate for your profile. This document serves as a realistic basis, not an online simulator.
- Add a safety margin above the estimated rate, usually a few tenths of a point. This margin absorbs fluctuations between the signing of the agreement and the actual obtaining of the mortgage.
- Check that the rate entered, combined with the amount and duration of the loan, produces monthly payments compatible with the 35% debt cap set by the HCSF. If not, adjust the duration or the amount borrowed.
The rate in the agreement should reflect what you can actually obtain, with a reasonable margin. Neither the dream rate nor a fanciful rate.
Common drafting errors in the financing clause
Beyond the rate itself, the drafting of the financing clause in the agreement contains technical pitfalls that many buyers discover too late.
- Failing to specify whether the rate is fixed or variable. A fixed rate at a certain level and a variable rate at the same level do not represent the same commitment. The clause must specify this.
- Not mentioning the number of banks to approach. Some agreements require soliciting multiple institutions. Failing to comply with this obligation can be interpreted as a lack of diligence on the part of the buyer.
- Confusing nominal rate and APR. The rate to be included in the agreement is generally the maximum nominal rate, not the APR which includes insurance and ancillary fees. Confusing the two distorts the entire clause.
The notary is supposed to verify these elements, but in practice, the financing clause is sometimes drafted from partial information provided by the real estate agent or the buyer themselves. Carefully reviewing this clause before signing remains the best protection.
The interest rate included in a real estate sales agreement is not an administrative detail. It is a legal parameter that conditions the validity of the loan contingency, the amount of monthly payments acceptable to banks, and the good faith of the buyer in case of dispute. Take the time to calibrate it with your broker or bank, have it validated by the notary, and review the financing clause word for word before signing.
