A family member wanting to buy your listing

An anonymised composite: the listing agent’s own sister wanted to buy the seller’s home. Why the fix was never about whether the agent could be trusted — it was about which disclosures RECO requires before anyone can find out.

At a glance

  • • A seller listed a $685,000 Ottawa-area home; three weeks in, the listing agent’s sister asked to make an offer on it.
  • • Two separate RECO obligations were triggered at once: a property interest disclosure to the seller and every offeror, and the general conflicts-of-interest four-step sequence.
  • • The agent could not act as the sister’s designated representative on this transaction while still representing the seller — RECO’s own guidance says multiple representation “requires a neutrality that is not possible” in this shape of conflict.
  • • The fix cost one referral and one written disclosure — not the sale, and not the agent’s ability to keep representing the seller.

The situation

A seller listed a $685,000 home with an Ottawa-area brokerage, working with a designated representative under a standard Seller Representation Agreement. Three weeks into the listing, the agent’s sister — who had been house-hunting independently, unconnected to the listing — saw the property online and asked her sibling to represent her in making an offer on it.

The problem

This was not a garden-variety multiple-representation question. RECO Bulletin 3.4 defines a person “related” to an agent to include “a relative by blood, marriage, or adoption of the agent or the agent’s spouse or child” — a sister qualifies without question. The bulletin’s property interest rule applies whenever an agent “knows or ought to know of an interest in the property that the client is considering buying or selling” held by a related person, and requires disclosure “to the client and every other person making or receiving an offer,” made “as soon as possible” and before any offer is made. Separately, the duties the agent owes the seller under Bulletin 3.5’s conflicts-of-interest sequence were also engaged, since a sibling’s interest in the sale price is exactly the kind of thing that can compromise an agent’s ability to negotiate hardest for the seller.

The numbers

The listing carried a standard 2.5% commission: 2.5% of $685,000 is $17,125. No part of this case turned on the amount — it turned entirely on who was allowed to negotiate that price on whose behalf, and what had to be disclosed, and to whom, before anyone could.

The rule that decided it

RECO’s Bulletin 3.4 addresses a closely related fact pattern directly: “the agent is representing their parents in the sale of their home” — and states that in that scenario “the agent could not represent a buyer in the trade” because “multiple representation requires a neutrality that is not possible in this situation.” The same logic reaches a sibling on the buy side of the agent’s own listing: the agent could disclose the sister’s interest and continue representing the seller, but could not also become the sister’s designated representative on the same transaction. Bulletin 3.5’s four-step sequence — disclose, advise independent advice, verify understanding, obtain consent — still had to run for the seller before the agent could take any further step, even the one step permitted: continuing to represent the seller while the sister proceeded through someone else.

What it would have cost otherwise

Had the agent simply represented both sides quietly — assuming family loyalty made the conflict manageable — the exposure would not have been a mispriced sale so much as an unmanageable one: no written disclosure on file if the seller later felt short-changed, no independent advice on record, and a transaction a discipline proceeding could unwind on the facts alone, since RECO’s own guidance already says this exact shape of conflict cannot be resolved by consent. The seller’s protection was never going to be the agent’s good intentions; it was the paperwork proving the conflict was disclosed before it mattered.

The tell

The tell was procedural, not personal: the moment the sister said “can you represent me,” the answer needed to be no before it was anything else, with the disclosure to the seller drafted the same day. Waiting to see whether the sister actually wanted to make an offer — treating the conversation as informal until an offer was real — is exactly the gap Bulletin 3.4’s timing rule closes: disclosure is due “as soon as possible” the agent knows of the interest, not once an offer exists to disclose.

The outcome

The agent declined to represent the sister and referred her to a colleague at a different brokerage the same week. The property-interest disclosure went to the seller in writing, describing the relationship and the fact that the sister was a prospective buyer; the seller acknowledged it and confirmed, in writing, wanting the agent to continue as listing representative. The sister’s offer, negotiated by her own agent with no relationship to the seller’s side, was one of two received and was not the one accepted — the seller took a competing offer $6,000 higher. Nothing about the outcome turned on the family relationship; everything about whether it could survive scrutiny did.

Takeaways

  • • A related person — RECO’s definition reaches spouse, child, and any relative by blood, marriage or adoption — wanting to buy your listing is a property-interest disclosure question the moment you know about it, not once an offer exists.
  • • You can usually keep representing your existing client through a family-interest conflict. You almost never can also represent the related buyer on the same transaction — RECO says that shape of multiple representation is not manageable by consent.
  • • Referring the related buyer to a colleague costs you one side of one deal. Skipping the disclosure risks the whole transaction and your standing with the client whose trust the rule exists to protect.
  • • Timing is the rule, not a nicety: disclosure is due as soon as you know or ought to know of the interest — treating it as informal until an offer materialises is the mistake, not the family connection itself.
