Sole agency, multiple agents and online-only models

Treat the sections below as a sequence. With agency agreements, getting the early decisions right makes the later ones much easier.

What the arrangements actually mean

Sole agency means one firm has the exclusive right to introduce buyers, though you may retain the right to sell privately without paying a fee. Sole selling rights goes further, usually meaning a fee is payable on any sale during the period, including one you found entirely by yourself.

Multiple agency allows several firms to market at once, with only the one who introduced the buyer being paid, normally at a higher rate. Joint sole agency ties two named firms together and splits a fee between them regardless of which one actually produced the buyer. The names are similar and the consequences are not, which is why the clause itself matters far more than what was said at the valuation.

Tie-in and notice stack together

A tie-in period fixes a minimum term during which you cannot instruct anybody else, and a notice period then runs after you decide to leave. Those two clauses add together, so a long tie-in with a further notice period can hold a property with an underperforming agent for months. Ask for the tie-in to be shortened before signing, because it is a negotiable term and agents expect competent sellers to raise it.

Where a property is not selling, the practical remedy is often a price change rather than an agent change, but you need the freedom to choose. Consumer contract rules in many jurisdictions give a cancellation window for agreements signed at home, so check what applies where you are.

The clause that creates a fee without a sale

Some agreements state that a fee becomes payable once the agent introduces a buyer who is ready, willing and able to purchase on your terms. That wording can make a fee due even if you then decide not to sell, because the agent has done exactly what the contract asked.

It is not so much a hidden trap as an unread one, and it appears in ordinary agreements rather than only in unusual ones. If you might withdraw, for instance because your own purchase could fail, ask for that clause to be removed or qualified in writing. Read what triggers the fee, when it is payable and whether it survives the end of the agreement, since a post-termination introduction period is common.

Traditional, hybrid and fixed-fee models

Traditional agents typically charge a percentage on completion, which aligns their interest with the price achieved and with the sale actually happening. Fixed-fee and online models charge a set amount, sometimes payable upfront and sometimes deferred, but due whether or not the property sells.

For most people, deferred payment arrangements are not the same as no sale no fee, and some become payable after a fixed period regardless of the outcome. The cheaper model works best where the property is straightforward, the area is liquid, and the seller will run viewings and chase progress personally.

The expensive model earns its keep on difficult sales, long chains and hard negotiation, which is precisely where a percentage fee is easiest to justify.

Reading the fee itself

Establish whether the quoted percentage includes sales tax, because the gap between the two figures is meaningful on a transaction of this size. Ask what is included: photography, floorplan, energy certificate, portal listings, a board, viewings and any charge for withdrawing from the market. Ask whether the fee changes with the price achieved, since a sliding scale can align incentives better than a flat percentage does.

Check for referral arrangements where the agent is paid for directing you to a conveyancer, broker or surveyor, which many jurisdictions require to be disclosed. A referral is not automatically bad, but you should know it exists and compare the recommended supplier against one you found independently.

Some of this will suit you and some will not, and that is the point.

Before you sign

Take the agreement away rather than signing at the valuation, because pressure to sign in the room is a sales technique rather than a necessity. Compare the three or four documents side by side on tie-in, notice, fee trigger, post-termination period and any withdrawal charge. Ask each agent how they arrived at their suggested price and what evidence supports it, since the highest valuation is often the least reliable.

Put simply, put any agreed variation in writing on the document itself and keep a signed copy, as verbal assurances are worth nothing afterwards. Agency regulation varies by country, and where a redress or ombudsman scheme exists, check the firm belongs to it before instructing them.

The takeaway

The valuation is the least important thing an agent tells you; the tie-in, the notice period and the fee trigger are the terms that bind.

Pick the one that costs you least, and let the rest wait.
