The Authority to Sell: Sole Agency vs General Agency, Explained

Selling Tips By Eric Wu 2026-07-22 4 Min Read

Listing with several agencies at once feels like it should widen your exposure. In practice it usually narrows it, and the reason is structural rather than moral: under a general agency, no agent can justify spending money on marketing a property another agent might sell. Before going further, the obvious disclosure — we are an agency, and agencies prefer sole agency. Read the reasoning below and judge it on its merits.

What Changes Under a General Agency

What a Sole Agency Should Buy You

Exclusivity is not a favour to the agent — it is what makes a proper campaign financeable and accountable. In return you should expect a written marketing plan with real spend behind it, one named person responsible for the result, scheduled reporting whether or not there is good news, and a defined term so the accountability has an end date.

Protect Yourself With the Term, Not the Structure

The genuine risk in a sole agency is being locked to an underperforming agent. The answer is not a general agency — it is a sensible term length and a clear written plan. Ask what happens if the campaign is not working at week three, and get the answer before you sign, not after.
