Estimate my property →The purchase offer — known in Quebec as the “promesse d’achat” — is the central document of every real estate transaction in the province. Through this form, the buyer officially expresses their intention to acquire a property under specific conditions. Once accepted by the seller, it becomes a legally binding contract under the Civil Code of Quebec.
In 2026, with a median price of $615,000 for a single-family home and $428,000 for a condo in Quebec, the financial stakes are considerable. A poorly worded clause or a forgotten condition can cost tens of thousands of dollars. This guide details every step of the process so you can sign with confidence.
Whether you are a first-time buyer or an experienced investor, understanding the mechanics of the purchase offer is essential. The Organisme d’autoréglementation du courtage immobilier du Québec (OACIQ) provides mandatory forms that govern the transaction and protect both parties. Let us examine in detail how this process works.

Estimate my property📜 The OACIQ form explained
In Quebec, real estate brokers are required to use mandatory OACIQ forms to draft a purchase offer. The main form is the “Promise to Purchase — Residential Immovable”. This standardized document covers all elements necessary for a secure transaction.
📋 Sections of the OACIQ form
1. Identification of the buyer and seller
2. Property description (address, cadastre, dimensions)
3. Offered price and payment terms
4. Conditions (financing, inspection, prior sale)
5. Declarations and legal warranties
6. Inclusions and exclusions
7. Occupancy date and deadlines
8. Signatures and response deadline
The form also includes mandatory schedules: the Seller’s Declaration on the Immovable (DPV), the General Schedule, the Financing Schedule, and the Inspection Schedule. The parties may also add customized schedules for particular conditions. Each schedule must be signed by both parties to be valid.
💡 Good to know: if you are buying without a broker (private sale), you can still use the OACIQ form available online, or have your purchase offer drafted by a notary. The important thing is that all essential clauses are present and clearly worded.
📝 The 7 essential clauses of a purchase offer
Every clause in the purchase offer has a direct impact on your rights and obligations. Here are the seven most important clauses to understand and negotiate carefully.
1. The offered price
The price should be based on a comparative market analysis (CMA): recent sales of similar properties in the same area. In March 2026, properties are selling on average at 98–102% of the asking price in Quebec. Offering too low risks immediate rejection; offering too high means overpaying.
2. The financing condition
This clause protects the buyer in case of mortgage refusal. It typically provides a period of 15 to 25 days to obtain formal approval. Get a mortgage pre-approval before making an offer to speed up the process and reassure the seller.
3. The inspection condition
The pre-purchase inspection allows you to verify the condition of the building before committing definitively. The usual deadline is 7 to 14 days after acceptance. If the inspection reveals major problems, the buyer can negotiate a price reduction, request repairs, or withdraw from the transaction without penalty.
4. The legal warranty
In Quebec, three options exist: full legal warranty (the seller guarantees quality and ownership), without legal warranty of quality(at the buyer’s risk), or limited warranty (to the seller’s personal acts only). Full warranty offers the best protection for the buyer.
5. The occupancy date
The occupancy date is when the buyer takes possession of the property. The typical timeline is 60 to 90 days after acceptance of the offer. This period allows for finalizing financing, signing the deed of sale at the notary’s office, and preparing the move. A flexible occupancy date can be a competitive advantage.
6. Inclusions and exclusions
Inclusions are movable property included in the sale: appliances, light fixtures, curtains, alarm system, heat pump, etc. Exclusions are items the seller takes with them. Be precise: indicate brand, model and location for each included item. Omissions are a frequent source of disputes.
7. The deposit
The deposit demonstrates the buyer’s seriousness. In Quebec, it is not mandatory but strongly recommended. The typical amount is 1 to 5% of the purchase price. The deposit is held in trust by the broker or notary and deducted from the sale price at the signing of the deed. If the transaction fails due to an unfulfilled condition, the deposit is returned to the buyer.
⏰ Seller response deadlines
The buyer sets a deadline in the purchase offer within which the seller must respond. This deadline is generally 24 to 72 hours. During this period, the buyer cannot withdraw their offer — it is irrevocable (art. 1396 of the Civil Code of Quebec).
Acceptance
The seller signs the offer. The contract is formed. Conditions begin to run.
Counter-offer
The seller modifies one or more terms. The initial offer is cancelled and replaced.
Refusal / Expiry
The seller refuses or does not respond within the deadline. The offer becomes null and void.
Strategic advice: a deadline that is too short (less than 24 hours) may be perceived as aggressive by the seller. A deadline that is too long (more than 5 days) may allow the seller to receive other offers. The optimal deadline is generally 48 hours, which gives the seller time to consider without dragging things out. In a seller’s market with multiple offers, the deadline may be set by the listing broker.
🔄 The counter-offer process
A counter-offer is the seller’s response when they wish to modify one or more terms of the initial purchase offer. Legally, a counter-offer cancels the original offer and constitutes a new proposal. The buyer can then accept, refuse, or issue their own counter-offer.
💰 Price — The seller proposes a different price, generally between the asking price and the offered price
📅 Occupancy date — The seller requests a longer or shorter period to vacate
🔧 Conditions — The seller refuses certain conditions (e.g., removing the inspection condition)
🏠 Inclusions — The seller modifies the list of items included or excluded from the sale
There is no limit to the number of counter-offers possible. Back-and-forth negotiations can last several days. Each counter-offer must be made in writing and signed. Negotiate the most important points first (price and conditions) and the details afterward (inclusions, occupancy date). Keep in mind that too many counter-offers can tire out the other party and lead to the failure of the negotiation.
⚖️ Conditional offer vs firm offer
The difference between these two types of offers is fundamental and directly affects your level of risk as a buyer.
✅ Conditional offer
Contains suspensive conditions: financing, inspection, sale of current property.
The buyer can withdraw if a condition is not fulfilled.
Recommended for the majority of buyers.
⚠️ Firm offer
No conditions: the buyer commits without reservation to purchase.
No way out if a problem is discovered after signing.
More attractive to the seller, but very risky for the buyer.
⚠️ Warning: in a highly competitive market with multiple offers, some buyers remove the inspection condition to stand out. This strategy is extremely risky. A hidden defect (foundation, roof, pyrite) can cost $30,000 to $100,000 to repair. We strongly advise against removing this condition.
🚨 Buying “at the buyer’s risk”: what it means
The clause “without legal warranty of quality” in the purchase offer means the seller does not guarantee the physical condition of the property. The buyer accepts the property as-is and waives all recourse in case of hidden defects. This clause is common in estate sales, bank repossessions, and sales by non-occupant sellers.
⚠️ Concrete consequences:
❌ No recourse for mould discovered after the sale
❌ No recourse for foundation or pyrite problems
❌ No recourse for plumbing or electrical defects
❌ Only exception: fraud (intentional deception by the seller)
Approximately 30% of transactions in Quebec are made without legal warranty of quality. If you are buying under these conditions, a thorough pre-purchase inspection is absolutely essential. Request additional tests (thermography, air quality, pyrite) and negotiate a reduced price to compensate for the assumed risk.
💡 Alternative: request a legal warranty limited to the seller’s personal acts. The seller does not guarantee defects that predate their ownership, but guarantees that they have not created or worsened any defects during their possession. This is a compromise between full warranty and no warranty at all.
🚫 7 common mistakes to avoid
Even with an experienced broker, these mistakes come up frequently. Avoid them to protect your investment.
1. Not including an inspection condition — A hidden defect can cost $30,000 to $100,000. An inspection costs $500 to $800. The choice is obvious.
2. Making an offer without mortgage pre-approval — You risk losing the property if financing is refused, and you lose credibility with the seller.
3. Forgetting to check inclusions — Appliances, light fixtures, curtains: anything not written down will not be included. Be thorough.
4. Setting a response deadline that is too short or too long — Less than 24 hours seems aggressive. More than 5 days leaves the door open for competing offers. Aim for 48 hours.
5. Not reading the Seller’s Declaration (DPV) — This document reveals known problems: past water infiltration, repairs, refused insurance. Read it carefully.
6. Ignoring the legal warranty — Accepting “without legal warranty” without understanding the implications can leave you with no recourse for a major defect.
7. Neglecting the certificate of location — This document confirms the property complies with municipal regulations. An expired certificate (over 10 years old) must be renewed at the seller’s expense.
👤 The role of the real estate broker
The real estate broker plays a crucial role in drafting and negotiating the purchase offer. Regulated by the OACIQ, they have a legal obligation to protect your interests and advise you adequately throughout the process.
✅ Comparative market analysis — The broker provides you with recent sales data to determine a fair price
✅ Drafting the offer — They ensure all necessary clauses are present and correctly worded
✅ Negotiation — They negotiate on your behalf with the seller’s broker or the seller directly
✅ Coordination — They coordinate the inspection, financing, notary and possession
✅ Legal protection — They ensure compliance with legal deadlines and alert you to potential risks
The buyer’s broker commission is generally paid by the seller through a sharing of the commission listed on the brokerage contract. The buyer therefore benefits from a professional’s services at no direct cost in most cases. However, with evolving practices in 2026, some brokers offer exclusive representation contracts with the buyer.
