Off market home sales explained: how hidden supply works

Some homes never enter the open supply in the same way. Some sit for days or weeks as ”coming soon” on Booli (the Swedish property portal) and Hemnet (the Swedish property portal) before the listing truly goes live. Others never show at all. They sell through the estate agent contact network, through an enquiry from a buyer the agent already knows, or through a quiet tip to a few selected house hunters.

Both variants come down to the same thing: the home changes owner before it becomes a full public listing anyone can find by searching ”for sale”, or without it ever becoming one. People call it private sale or off market, sometimes hidden supply. It is more common than many think, and it grows as both Booli and Hemnet signal what is coming ever better. Readers who only want the short answer to what off market is find it on its own page.

What does a private sale mean in practice?

A private sale, in industry terms often off market, means the home is never published openly. No Hemnet listing. No open viewings for anyone. Instead the home is shown to a handful of buyers the estate agent judges serious and ready.

It can be a flat, a house or a terraced house. What matters is not what it is, but how it sells. The sale runs quietly, and most of the market never learns it happened. With a home alert you can still become visible to sellers looking for buyers in silence.

Coming soon: the visible part of the hidden supply

Between the fully open listing and the fully invisible off market sale sits a middle stage: the ”coming soon” or ”arriving shortly” status you find on both Booli and Hemnet. It is not the same as a full off market sale, since the home is actually heading for a public listing, but it is not there yet.

A coming soon post usually shows area, home type, an approximate room count and sometimes an indicative price, but no address, no photos and no way to book a viewing. The estate agent posts it on purpose, often weeks before the real listing goes live, to start building a list of interested buyers and to test demand for that exact home.

It lets the seller have it both ways. The agent reads the market and collects serious house hunters calmly, while the home still reaches the wider open supply in time, with photos, viewings and bidding, if the seller picks that route. Some coming soon homes do sell before they become a full listing, and then slide into the off market category instead.

Why do estate agents and sellers use ”coming soon” status?

For the estate agent it is a tool to test the temperature. If the home draws many expressions of interest before it goes live, the agent knows the pricing is probably right, or even cautious. If interest is cool, they can adjust the strategy before the listing truly launches.

For the seller it means a softer start. You skip the whole neighbourhood gaze from day one, and you gain a head start in time: the keenest buyers contact you directly, before competition from the whole Hemnet audience arrives.

It also builds expectation. A home shown as ”coming soon” for two weeks can go live with an already warm queue of house hunters, which often helps the seller once bidding starts.

Why do sellers go fully off market?

The reasons resemble those behind coming soon, but more strongly held. Many sellers want to skip the whole machine of open viewings, photography and intense bidding. They want a serious buyer fast and calmly, without the neighbourhood ever learning they sold.

Others want to test the market one to one with the agent. A couple of selected buyers are contacted, interest is sounded out, and if a good offer arrives at once neither a coming soon post nor a real listing ever needs publishing. If several of the selected buyers want the home, the sale is often settled by closed bidding instead of an open bidding fight.

And some sellers simply want discretion all the way. Perhaps they sell to a neighbour or someone in their circle. Perhaps it is a costly or unusual home where the seller wants to avoid curious eyes and price speculation.

Who gets the chance, and how do you track hidden supply?

In a pure off market sale the answer is simple: buyers the estate agent already knows. For coming soon it is more open. Anyone can in theory see the post if they track the right area, but only active searchers act in time before the home goes live or sells quietly.

There are concrete steps you can take. Set up alerts on both Booli and Hemnet for the areas and home types you want, so you get a notification as soon as a coming soon post appears, not only when it becomes a full listing. Also follow the estate agent offices active in your area. Some share early signals in their own channels before they show on the portals.

Have your mortgage pre-approval ready and updated before you need it. The coming soon window can be short, sometimes just a week, and a buyer with financing in place can contact the agent the same day the post appears, long before anyone still waiting on a bank decision.

Pitfalls of coming soon listings

The price shown in a coming soon post is a hint, not a promise. The estate agent and seller can adjust it up or down when the listing goes live, depending on interest during the preview phase. Never fix a budget from an indicative price you saw weeks before the viewing.

Nor is there any guarantee the home reaches the open supply. Some coming soon homes sell quietly before they become a real listing, just like a pure off market sale, which can feel frustrating if you waited to book a viewing.

And you are rarely alone in spotting the post early. Other buyers track the same areas, and some already hold financing. Seeing a coming soon post gives you a head start in time, not a guarantee of escaping competition.

Is hidden supply good or bad for you as a buyer?

It depends where you stand. If you are in the process, whether for a coming soon post or a pure off market sale, it can help. Competition is often lighter, the pace calmer, and you get a chance most others never even hear about.

If you are not in, it is a closed door. And there is a catch for buyers at large: a narrower circle of house hunters can mean weaker insight into what the home is truly worth, above all in pure off market sales where not even an indicative price shows.

Off market sales and coming soon posts are legal and normal parts of how the Swedish housing market actually works. As a buyer it pays more to adapt to it than to wait for the market to turn different.

How to raise your chance of reaching hidden supply

Build relations with estate agents active in the area you search. Contact them, tell them what you look for and show you are serious. A buyer with a clear mortgage decision who knows exactly what they want is easy for an agent to call when a discreet instruction lands, or to prioritise when a coming soon post goes out.

Be clear and concrete. ”Three rooms, lift, around 4 million, in these districts” tells an estate agent far more than ”something central”. The easier you are to place, the more often you make the list, and the faster you can act when something appears as ”coming soon”.

Registering a buying brief at SökHem is another way to get visible. You describe what you want, and the system proactively looks for sellers who match, including sellers weighing a sale without a listing and sellers about to post their home. When a home fits your criteria we contact you. It is the same logic that drives all hidden supply: the right buyer, the right moment, with no detour through a public listing.

Summary

Hidden supply is no closed club for insiders and the wealthy. It stretches from coming soon posts anyone can track, to fully silent off market sales only a handful of known buyers ever see. What they share is that a visible, prepared and fast buyer goes further than one who waits for everything to reach the open supply.

When supply is thin and competition hard, the hidden channel can decide between finding your home and waiting one more year. So start your alerts and your mortgage pre-approval now, and you stand ready next time a post appears.
