Why the Same Property Appears on Six Sites at Three Prices

Search for a three bedroom in Lekki and you will meet the same flat several times before you have finished scrolling. Same living room, same slightly overexposed photograph of the kitchen, four different agents, and a price that moves by fifteen million between the cheapest listing and the dearest.

Every buyer notices this. Most of them draw the obvious conclusion, which is that somebody is lying. And you, as the agent who actually holds that mandate and quoted the honest number, get to spend the first part of every conversation explaining a mess you did not make.

So what is actually going on? Two completely different things, is the answer, and the fact that they look identical from the outside is most of the problem.

The Two Things That Look the Same

One property, several agents, one mandate holder. This is an open mandate, and it is legitimate. The owner has instructed more than one agency, or has instructed one who has openly invited others to bring buyers. Everybody involved knows the arrangement, and in a functioning market this is normal and useful. More agents looking for a buyer is not a problem.

One property, several agents, one copied listing. Somebody saw your post, lifted the photographs and the description, added their own number, and put it out as their own. No mandate, no conversation with the owner, sometimes no knowledge of whether the property is even still available. This is not a variation on the first thing. It is a different act entirely.

From the buyer’s side, though, these are indistinguishable. She sees the same flat four times either way. She has no way to tell an open mandate from a copy, and neither, in most cases, do you, which is why “is this one real?” has become the first question in Nigerian property rather than the last.

The absence that makes them indistinguishable is a record of origin. Not a nicer website. A record that says this property entered the market on this date, held by this agent, at this price, and everything else is a copy of that.

The difference is not how many places the property appears. It is whether one of them is the original.

Where the Three Prices Come From

Prices diverge for reasons that are mostly boring, which is worth knowing because it stops you assuming everybody else is a criminal.

The copy went stale. Your price moved in June. The copy did not, because whoever posted it has not thought about that property since March.

Somebody added their cut. An agent without a mandate adds two million on top so there is something in it for them if a buyer bites. They are not planning to defraud anybody. They are planning to negotiate.

The copy was made from a copy. By the third generation the description has drifted, a bedroom has appeared, and the price has been adjusted twice by people who never saw the property.

And sometimes the owner genuinely told two agents two numbers. It happens more than anybody admits, and when it does, no software in the world is going to rescue the situation.

Only the last of those is anybody’s dishonesty. The rest is a market copying data by hand and getting the ordinary result of copying data by hand.

What It Actually Costs You

This is the part that usually goes unsaid, because the conversation about duplicate listings is normally about buyer trust in the abstract. Let us make it about your money instead.

Your advert competes with a cheaper version of your own property. If you are running a Meta ad on that flat and a copy exists at eleven million less, the copy is doing your negotiation for you, in the wrong direction, before the buyer has spoken to anyone. You are paying to send buyers into a comparison you lose.

You anchor against the lowest copy, not against the market. Buyers do not average the four prices they saw. They remember the smallest one. So the negotiation starts below where it should, and you spend your credibility climbing back to the real number.

Two agents bid up the same click. When several people advertise one property, the cost of reaching that buyer rises for all of them, and the buyer arrives more confused than if only one advert had existed.

You pay a suspicion tax somebody else earned. She has heard the stories, we all have. So she slows down, asks more questions, and takes longer to commit, and a few of those enquiries never convert at all. Not because you did anything wrong. Because she had no way of telling you apart from the copy sitting next to you in her search results.

And when you tidy your feed, you delete your own history. As an agency grows it reworks its social presence, removes older listings, and starts presenting a higher price band. Perfectly sensible for brand perception. From a sales standpoint you have just deleted your own record of what you sold, to whom and at what, which was the only place it existed.

Why Posting More Carefully Does Not Fix It

The instinct is to solve this individually. Watermark the photographs. Put your number in the image. Post less detail so it is harder to lift.

None of that works for long, and some of it costs you buyers, because a listing with the address obscured and a watermark across the kitchen is a listing that converts worse. You end up defending your inventory by making it less useful, which is a poor trade, and it does nothing at all for the buyer who is sitting with four prices and no way to choose between them. The case for the opposite approach is in one listing per property.

The reason individual effort does not fix it is that this is not an individual problem. A copied listing is only possible because there is no authoritative version to copy from. Give every agency in Lagos a better private system and you have several hundred excellent private systems that still disagree with each other, and a buyer who still sees four prices. We argued that at length in Nigerian real estate does not have a technology problem.

What a Shared Record Changes, Specifically

Not everything, and not overnight. But the mechanism is worth stating plainly.

When a property exists once, in a place where the entry carries a reference, a date, a status and the name of the agent responsible for it, then the comparison a buyer is making changes shape. She is no longer comparing four listings of unknown provenance. She is looking at one record, and at whatever else is floating around, and the record is the thing she can check. It is also the version that appears on member websites through an IDX connection, which is how one accurate entry ends up in more places than six inaccurate copies ever reached.

The distinction this article opened with, between an open mandate and a copy, is the awkward part to automate, and it is worth saying how ours actually handles it, because the honest answer is not “we detect duplicates”.

Two layers. An exact match, meaning the same title, address, area, listing type and price band, is blocked outright at the point of listing. A looser match, meaning the same local government area, neighbourhood, price band and specs, is treated differently depending on who is listing it: the same agent is blocked, because that is somebody listing their own property twice, and a different agent is flagged for a human rather than blocked.

That second rule is the whole point. Two agents on one property might be a copy, and it might equally be an open mandate or two genuinely different units in the same development. Blocking it would punish the legitimate case, and allowing it silently is where we came in. So it gets looked at.

That is also what makes an open mandate work properly rather than messily. Several agents can be selling the same property, which is fine, while there is still one record of what the property is and what it costs. The cooperation happens on top of the record rather than instead of it. This is why a multiple listing service is a set of shared rules before it is software, and it is the whole argument of what a multiple listing service is, and what Nigeria has instead.

Verification of the person works the same way, incidentally. Nigeria has professional registers for exactly this purpose, including the Nigerian Institution of Estate Surveyors and Valuers and its lists of members and registered firms. A listing record simply does that job one level down, at the property rather than at the practitioner.

What You Can Do This Week

Three things, and only one of them involves us.

Search for your own listings the way a buyer would. Not your name, the property. Type “3 bedroom flat for rent in Gbagada” or whatever yours is, and look at what comes back. You will usually find at least one copy of something of yours, and you cannot manage a problem you have not looked at.

Keep one place where your listing is definitively current. Whatever that place is, keep it accurate and keep it dated, and point people at it. The copies will still exist. What changes is that there is now an original for anybody who cares to check.

List where the mandate is recorded, not just the property. That is the difference between a database of flats and a record you can defend. If you want to see what that looks like in practice, the MLS is here, and if you would rather ask a person than read a page, tell us what you are dealing with.

The copies are not going to stop. What is available to you is being the version that can be checked, and in a market this short on trust, that turns out to be worth more than the watermark ever was.
