How long does the seller have to respond?
How Fast Will a Seller Reply? The Exact Seller Response Timeline Every Milton Buyer Needs to Know
Why this matters: offers move fast in Milton. Get the timeline right or lose the deal. Read this and act.
Quick answer: seller response time in Milton, Ontario
In Ontario, a seller can accept, counter, or reject an offer any time before signed acceptance is delivered — unless the offer includes an irrevocable period. In real-world Milton practice, sellers normally respond within the irrevocable window buyers set (commonly 24–72 hours) or by the seller’s requested deadline in a Multiple Offer scenario. If there is no irrevocable time, the seller can lawfully revoke the offer before accepting it. Delivery of acceptance (signed agreement returned to buyer or buyer’s agent) is what finalizes the deal.
Why this matters for Milton buyers and sellers
Milton is part of the GTA housing market. Properties get multiple offers. Knowing exactly how long a seller has to respond protects your leverage, your deposit, and your closing timeframe. Misreading timelines creates lost opportunities and legal headaches.

The legal backbone: Ontario rules that control offers
- Contract law governs offers and acceptances in Ontario.
- An offer is effective when communicated to the offeree. Acceptance is effective when communicated back to the offeror.
- Sellers and buyers can add an irrevocable clause — a fixed time window during which the offer cannot be withdrawn.
- Without an irrevocable clause, either party may revoke the offer before acceptance is communicated.
- Standard OREA forms include spaces for irrevocable times and deadlines for conditions (subjects).

Common seller response scenarios in Milton
- Offer with a clear irrevocable period
- Buyer sets an irrevocable time (e.g., “Irrevocable until 5:00 PM on Tuesday”).
- Seller must accept before that time for the offer to remain binding.
- If the seller signs after that time and the buyer didn’t agree to extend, the seller’s signature is not an acceptance.
- Offer without an irrevocable period
- The seller may accept or revoke any time before acceptance is communicated.
- In practice, agents treat offers as active until withdrawn or rejected, but no legal guarantee exists.
- Multiple offers / seller-imposed deadline
- Sellers often call for “highest and best by” dates.
- Those are effectively irrevocable deadlines for competing offers.
- Buyers should honor the requested timeline or risk losing consideration.
- Counter-offers
- A counter-offer rejects the original offer and becomes a new offer with its own irrevocable timeline.
- Original offer is no longer available once countered.
Typical timelines you’ll see in Milton listings
- Irrevocable windows: 24–72 hours (most common: 24–48 hours).
- Subject removal (conditions like financing or inspection): 5–10 business days.
- Closing dates: 30–90 days depending on seller needs.
- Deposit release: Often required within 24–48 hours of firm acceptance.
These are market norms. Sellers and buyers can negotiate other timelines.
Practical rules that protect buyers and sellers
- Put an irrevocable time in every offer. If you want certainty, name the exact deadline and timezone.
- Specify method of communication for acceptance: email, fax, signed PDF delivered, or physical delivery.
- Use clear subject-removal deadlines. For example: “All subjects to be removed by 5:00 PM two business days after acceptance.”
- Keep proof of delivery. Save emails, time-stamped texts, and confirm receipt with the listing agent.
- If you plan a multiple-offer strategy, ask your agent to confirm the seller’s deadline in writing.

How agents in Milton handle response timing (best practices)
- Listing agents will advise sellers on timing to maximize offers — e.g., set a 24–48 hour irrevocable to create urgency.
- Buyer agents often include quick subject-removal periods to make offers stronger.
- Both sides exchange signed offers by email or secure e-sign platforms. Once signed and received, the contract is firm.
These practices are standard across Milton brokerages.
Step-by-step: what happens when you submit an offer in Milton
- Draft offer using the Ontario standard forms (OREA or equivalent).
- Include price, deposit, irrevocable time, subject conditions, closing date.
- Deliver offer to listing agent and confirm receipt.
- Seller reviews. They can accept, counter, or reject within or before any stated irrevocable period.
- If seller accepts and signs, they return a signed copy — acceptance is effective on delivery.
- If the seller counters, the buyer can accept, counter again, or walk away. Countering restarts the timeline.
What buyers should do to get fast responses
- Use strong, clean offers: adequate deposit, short subject periods, and clear irrevocable time.
- Communicate availability and flexibility for quick closing if needed.
- Request confirmation of receipt immediately and follow-up until the deadline.
- Be ready to remove subjects quickly (inspectors and mortgage approval lined up).
What sellers should do to manage response time and offers
- Decide in advance whether you want a deadline for offers.
- Use a clear irrevocable deadline to create competition and avoid late offers.
- In a multiple-offer situation, ask agents for “highest and best by” and set a single cut-off.
- Keep communication documentation. Make sure your agent knows how you want to handle late offers.

Edge cases and tricky moments (avoid these)
- Late acceptance: If the seller signs after the irrevocable time and the buyer did not agree to extend, the contract may not be valid.
- Oral acceptance: Verbal acceptance without signed documents or clear confirmation is risky. Always get it in writing.
- Electronic delivery issues: Email delay or spam rules can jeopardize acceptance timing. Use read receipts and confirm with a call.
How local law and practice affect disputes in Milton
Disputes over timing are resolved under Ontario contract law. Courts look at whether acceptance was communicated before revocation or expiry. In practice, lawyers examine timestamps, emails, and signatures. Good documentation usually prevails.

FAQ — Offers & Negotiation in Milton, Ontario
Q: How long does a seller legally have to respond to an offer in Milton?
A: Legally, a seller can respond any time before acceptance is communicated. If the offer includes an irrevocable period, the seller must accept before that deadline. Without irrevocable wording, the offer can be revoked before acceptance.
Q: What is an irrevocable period and why use it?
A: An irrevocable period is a fixed deadline the buyer sets during which they promise not to revoke the offer. It gives the buyer certainty and forces the seller to decide by a set time.
Q: Can a seller accept an offer after the irrevocable period?
A: Only if the buyer agrees to extend the deadline or if communication shows the buyer accepted the late acceptance. Otherwise, the late acceptance is generally ineffective.
Q: How do multiple offers change response timelines in Milton?
A: Sellers often set a deadline for “highest and best” offers. Buyers must submit their best offers by that time. Agents usually set a firm cut-off to manage multiple offers.
Q: Does electronic signing count as acceptance?
A: Yes. Electronic signatures and emailed signed PDFs are valid if delivered and received. Keep timestamps and confirmations.
Q: How quickly should subjects be removed?
A: Commonly 5–10 business days for financing and inspection. In hot markets, buyers often shorten this to 48–72 hours to be more competitive.
Q: What if an offer is accepted but the buyer later changes their mind?
A: Once both parties accept in writing, the contract is binding. Backing out can lead to forfeiture of deposit and potential legal action unless permitted by a subject clause.
Q: Who resolves disputes over response timing?
A: Typically, a real estate lawyer or the courts under Ontario contract law. Documentation (timestamps, emails, signed forms) is critical.
