What Singapore property agents see before you do

Quick answer: PropertyGuru and 99.co carry the large majority of Singapore's active resale and rental listings, and they are the right first stop for any buyer. What a solo search on the portals will not always show you is a listing still being prepared before it goes public, a seller quietly testing interest through an agent's own network first, or the more current professional transaction data that agents use to judge whether an asking price is realistic. An agent does not replace the portals. An agent adds a second, earlier channel on top of them.

Most buyers assume the portals show everything. PropertyGuru and 99.co are genuinely comprehensive for what has been submitted to them, and they should always be part of a serious search. But a portal listing is the end of a process, not the start of one. By the time a unit is photographed, priced and uploaded, an agent's network has often already known about it for a stretch of time. That gap, small on any single listing, compounds into a real difference in what a buyer sees across a search that runs for months.

How a listing actually reaches the public portals

A seller does not wake up and post a unit online. In the ordinary sequence, a seller first engages an agent, usually under an exclusive listing arrangement for a set period, or occasionally an open listing with more than one agent at once. The agent then arranges photography, sets an asking price with reference to recent comparables, and prepares the listing copy before it is submitted to PropertyGuru and 99.co. Only at that point does the unit become visible to a buyer searching alone.

Almost every exclusive listing in Singapore explicitly allows co broke, where the seller's agent shares their commission with a second agent who introduces a buyer. Because co broke is the norm, information about a newly signed listing routinely reaches other agents, through agency systems, professional group chats and direct relationships, before the finished listing appears publicly. It is common industry practice for a unit to circulate this way for a day or two while it is being prepared for the portals, though the exact gap depends on the agency, the property type and how quickly the seller wants to move. A buyer with an active agent hears about the unit during that window. A buyer relying only on the portals hears about it once it is already competing for attention with every other listing in the area.

The professional data gap: REALIS versus the public view

Beyond listings, there is a separate and more measurable gap in transaction data itself. According to URA, the Urban Redevelopment Authority operates REALIS, a subscription research platform used mainly by real estate professionals and analysts, alongside the free transaction data it publishes to the public. Caveats lodged with the Singapore Land Registry are transmitted to URA and reflected in REALIS on a regular update cycle, giving subscribers a more current and more granular view, covering resale, rental and supply pipeline data down to project level, than the summarised public views most buyers rely on.

This matters for one very practical reason. An agent pricing a unit, or advising a buyer on whether an asking price is realistic, is working from a fuller and fresher comparable set than a buyer cross checking a handful of recent listings on a portal. It does not mean the public data is wrong. It means it is a thinner slice of the same picture.

The listings that never reach a portal at all

A smaller category of opportunity never becomes a public listing at all. Some sellers, often relocating for work, going through a change in family circumstances, or simply preferring discretion, ask their agent to quietly test interest within their own network before committing to open marketing. This is not a hidden inventory that dwarfs the public market, most stock does eventually reach PropertyGuru or 99.co, but for a buyer with a narrow, specific brief, an agent's relationships and past client base are the only channel through which this smaller category ever surfaces at all.

Solo search versus agent assisted search

General patterns, not a guarantee for any specific transaction. Always confirm commission and representation arrangements in writing before an agent begins work.

What this means for your search

The practical takeaway is not to abandon the portals, they remain the broadest single view of the market and should stay open in a browser tab throughout your search. The point is to add a second channel on top of them early, before you have shortlisted, so both channels are running for the full length of your search rather than only the tail end of it. A clear brief, budget, location, unit type and must have features, given to an agent at the start of your search is what lets that second channel actually work in your favour rather than producing noise.

Frequently asked questions

Do buyers have to pay a property agent's commission in Singapore?

In a standard resale transaction, buyers typically pay nothing. The buyer's agent is paid a co broke share of the commission the seller has already agreed with their own agent. For new launches, the developer pays the agent directly. It is unusual for a resale buyer to be asked to pay commission on top of that.

What is a co broke listing?

Co broke means the seller's agent agrees to share their commission with a second agent who brings a buyer, rather than insisting on handling both sides alone. Most exclusive listings in Singapore permit co broke, which is how a buyer's own agent can access a unit that another agent originally signed with the seller.

Are PropertyGuru and 99.co missing listings buyers should know about?

The portals carry the large majority of active resale and rental listings and remain the right first stop for any buyer. What they will not always carry is a unit still being prepared for marketing, a seller who has asked their agent to sound out interest quietly before committing to a public listing, or the newest transaction data feeding into pricing decisions.

How much earlier do agents typically hear about a new listing?

There is no fixed rule, but it is common industry practice for a newly signed listing to circulate within agent and co broke networks for a day or two before the finished listing, with photography and floor plans, goes live on the public portals. The exact gap varies by agency, property type and how quickly the seller wants to move.

Should I just contact the seller's agent directly instead of engaging my own agent?

You can, but the seller's agent owes their contractual duty to the seller under the Estate Agency Agreement they signed, not to you. Engaging your own buyer's agent gives you someone whose brief is to represent your side of the transaction, sourcing options and coordinating on your behalf, while the seller's agent continues to work for the seller.

Does URA's own data confirm agents see more than the public?

URA publishes private property transaction data to the public and separately operates REALIS, a subscription research platform used mainly by real estate professionals and analysts, which carries more granular and more frequently updated transaction, rental and supply pipeline data than the free public views most buyers rely on.
