When the apartment listing is too good to be true

On 31 July 2026 my Immoscout24 alert surfaced a flat in Zürich, below market, all utilities included, available immediately. I applied. An hour later the listing was gone. Normal enough in this market, where advertisers pull ads once the applications bury them.

The reply came on Monday morning, and not from the agency. It was polite, fluent, and had an answer already prepared for every objection I could think of, including the one I was fairly sure had no good answer. They had two.

Methodology note

Everything below is a scambait. I was confident this was fraud from the first email and played along to see how far it went. I never sent money, and the reservation funnel was examined in a throwaway sandbox with no credentials and no browser sessions. All URLs, domains and email addresses are defanged. Do not visit them.

The lure

The flat was at Bristenstrasse 20, 8048 Zürich. The property is real: the photos were almost certainly lifted from a legitimate listing for that address, so reverse-image search would probably have returned a genuine apartment. The flat is real. The operator simply has no relationship with it.

The listing claimed to be managed by IMMOPRO gérance Béatrice Jotterand Sàrl, a real Swiss agency. The reply came from a private individual on a .de domain who then routed me to a third “agency” trading under a stolen industrial brand name, ThyssenKrupp Immobilien. All three names are the operator’s. Both real companies are borrowed props with no involvement beyond having their names used, and the names do not even match each other, which is the tell: recycled identities, not rotated between listings.

Nothing appears to stop this at the source. As far as I can tell, anyone can register on Immoscout24 and advertise under any agency name they like. The name on a listing is a string the advertiser typed, not a verified credential, so borrowing a real agency’s identity costs the operator nothing.

Three things were wrong with the price. Two of them were visible on the listing itself, at CHF 2,350/month all inclusive; the third only showed up once the reply arrived:

• Electricity and internet were included. All-in Pauschalmiete pricing does exist, mostly for furnished lets, so “everything included” is not impossible by itself. Electricity is: in Zürich it is a contract in the tenant’s name with EWZ, not something a landlord bundles. Internet and TV are the same story.
• A parking space in Zürich is its own market, routinely a few hundred francs a month, let separately because it is worth letting separately. Nobody throws one in for free.
• The currency changed. On Immoscout24 the rent was CHF 2,350. By the time it reached the email and the payment page it was €2,350: same digits, currency symbol swapped, no conversion performed. Zürich rents are quoted in francs; a German-domiciled “agency” billing a Swiss flat in euros is a template built for another market and never localised.

The emails

Both were in German; translations below, originals collapsed under each. The wording is boilerplate, and searching a phrase from it is how many people discover they are being worked.

I asked for the link. It arrived immediately:

hxxps://thyssenkrupp-immobilien[.]de/property.php?slug=4324113633

That last line is defensive. Mail from a freshly registered .de domain has a good chance of being filtered, and a spam label arriving at the moment the victim is deciding whether any of this is real would break the spell.

The property page is preserved as an archive.is snapshot: generic hero image, stock trust badges, AI-generated copy that says a lot and commits to nothing.

What each element is doing

• The absent landlord. “Moved permanently to Italy… health problems” pre-explains the one thing that would end the conversation. Sympathy is the delivery mechanism; the payload is no viewing before payment.
• The agency as trust layer. A private individual asking for €4,700 up front is suspicious. An agency asking is procedure. “ThyssenKrupp Immobilien” looks legitimate enough, and nobody can be expected to know every real-estate agency by name. There are thousands, most of them small, and an unfamiliar one is the normal case rather than a warning sign.
• Reversibility. “You can cancel at any time and receive the full amount back”, offered for a SEPA credit transfer to a private foreign account, which has no cancel button. It is also only the opening bid; the website improves on it considerably, which is the next section.
• Scarcity. “Reserved exclusively for you.” In a city where 500 people once queued for one viewing in Oerlikon, exclusivity is the most valuable thing anyone can offer, and the one thing no honest Zürich landlord offers.

Why the hell would you send €4,700 to a random bank account?

Nobody sends thousands to a stranger for a flat they have not seen. The operator knows that, and answers it twice: once in the email (“cancel any time, full refund”), and once on the site.

The funnel is three pages: register.php → book.php → payment.php. You register, pick a viewing date, “reserve” the property, and land on a payment page demanding first month’s rent plus deposit (€2,350 + €2,350 = €4,700) within 24 hours against a booking reference.

The page advertises tenant protection: we hold your payment and only release it to the landlord 48 hours after you move in. That is why the site exists. A refund promise is only as good as the stranger making it; escrow requires trusting nobody. It is also an answer with the shape of a real one, borrowed from property sales and short-let platforms. No Swiss residential letting works this way: the equivalent is a blocked deposit account opened after signature, which is exactly the step the site replaces.

There is no escrow. There is a bank account.

Two details make the design deliberate:

No card processor anywhere. No Stripe, no PayPal, no Klarna, no card form. On its own that is a weak signal, since Swiss and German agencies do not take rent or deposits by card either. What matters is the consequence: cards carry chargeback rules, SEPA credit transfers do not, and the one rail with a reversal mechanism is never offered. Irreversibility is the product requirement.

The payment page asks you to upload your payment receipt. It tells the operator the transfer is inbound so the money can be moved onward, and it hands over a bank document with your real name, address and account details.

After payment the pattern is well documented: the viewing is “being confirmed”, a second extraction is attempted (rental insurance, key courier fee, contract handling), then the channel goes dark.

Follow the money

A German agency, renting a Swiss apartment, in euros, into a private account at a Spanish retail bank. Together those mismatches describe a money mule: an account opened by a recruited third party or with a stolen identity, whose only function is to receive victim transfers and forward them onward, typically within hours.

A caveat, since I am publishing the name. Mule holders are sometimes co-conspirators and sometimes victims themselves, of identity theft or of a “financial agent” job advert. I cannot tell which from the outside. Do not contact this person, and do not treat the name as an accusation: it is the string that appeared on a payment page. The IBAN is the artefact that matters, and ING can resolve it.

The account is also the most fragile point in the operation. Domains are disposable; a bank account receiving fraud transfers is attached to a real identity and can be frozen.

Infrastructure

The domain was one day old. The registrar record puts creation at 2026-07-30T11:28:16Z, with the record last updated four seconds later. DENIC does not publish creation dates for .de in public whois, so this comes from the registrar-side record rather than the registry, and dates obtained that way are worth treating as approximate. The listing surfaced on my alert the following evening, and the emails arrived three days after that. A “letting agency” whose domain predates your enquiry by a day is infrastructure provisioned for this campaign, to be abandoned as soon as it is reported. Domain age is free to check and one of the strongest single indicators available.

Domain Name: thyssenkrupp-immobilien.de
Registrar WHOIS Server: whois.ionos.com
Registrar URL: https://www.ionos.com
Creation Date: 2026-07-30T11:28:16.000Z
Updated Date: 2026-07-30T11:28:20.000Z

All three domains sit at one provider. Two adjacent IPs, ui-dns nameservers, IONOS MX for the mail domain. The adjacency is weaker evidence than it looks: 217.160.0.0/19 is IONOS mass shared hosting, where neighbouring addresses say nothing about who the customer is. What ties the domains together is the traffic between them, since the “independent landlord” hands off to the “independent agency” by email and link. Either way, one abuse report to IONOS covers all three.

The site runs a tawk.to live chat, answered in real time, in German. When a hesitant victim wants reassurance before transferring €4,700, there is a human to provide it. This is staffed, not a fire-and-forget kit.

The site auto-translates by IP geolocation, with a language map covering DE, AT, CH, RO, FR, ES, IT, PL and NL. That is the target list; Zürich is this week’s listing. The RO entry stands out in a list otherwise made of victim countries, and it is tempting to read it as the operator’s own locale. It is not evidence of one: Romanian-speaking renters in Germany, Austria and Switzerland are a large enough group to be worth translating for. I have nothing that identifies who runs this, and I am not making an attribution.

The corporate details are stolen, not invented. HRB 25360 is genuine and belongs to thyssenkrupp Services GmbH, copied out of the German commercial register and pinned to an unrelated site. Every German site carries an Impressum by law, scam ones included, and its identifiers can be real without belonging to whoever published them. The check is not does this number exist but does it resolve to the company claiming it.

Red flags, in the order you’ll meet them

1. Rent noticeably below market, with every utility included.
2. The landlord is abroad and cannot do viewings.
3. You are handed off to an agency you did not choose, on a domain that is not the agency’s real one.
4. The price changes currency, or stops following local pricing conventions, once you are off the listing platform and into the email thread and the agency’s own site.
5. Payment required before any viewing.
6. Bank transfer only. Legitimate lettings use transfers too, so this is not damning by itself, but it does mean nothing can be reversed.
7. A deposit of one month’s rent. Swiss deposits are normally two or three months, capped at three by Art. 257e OR.
8. Receiving account in a third country, held by a private individual.
9. A 24-hour deadline.
10. You are asked to upload a payment receipt.
11. “Cancel any time, full refund”, for a payment method with no refund mechanism.
12. The agency’s domain is days old.

Compressed: money before keys is the scam. A real Swiss agency shows you the flat first and takes the deposit after a signed lease, into a Mietzinsdepot: a bank account in your name, which the bank may release only with both parties’ consent or a court decision, and which reverts to you a year after the lease ends if the landlord has brought no claim.

That is worth putting next to the fake escrow. Swiss law already gives the tenant the protection the site was pretending to offer, and it gives it in the tenant’s own name at the tenant’s own bank. What the operator built is a counterfeit of a mechanism you are entitled to for free.

If you have been scammed

Do these three now, in this order, because a SEPA transfer only stays recallable for a matter of hours.

1. Call your bank and ask them to recall the transfer.
2. Call the receiving bank, here ING Spain, and report the account for fraud. It is the part of the operation that can actually be frozen.
3. File a police report where you live. Your bank will ask for it.

Where to report these scams

Spotting it and walking away only protects you. The listing stays up, and the next person to answer it may be in more of a hurry than you were, so the reports below are the part that actually costs the operator something.

• The hosting provider. Resolve the domain to an IP and run a whois on both: the domain record names the registrar, the IP record names whoever runs the network, and each publishes an abuse contact. Here both roads led to IONOS and abuse@ionos.com, so one report covers all three domains.
• The listing platform where you found the ad.
• The national cybercrime reporting point in your country.

In my case no money moved, so there was nothing to recall. What I did:

• reported the hosting to abuse@ionos.com;
• reported the mule IBAN to ING’s fraud team at fraude@ing.com, since the account is the part that can be frozen and a report from someone who was not scammed still puts it on their radar;
• filed a report with the Swiss NCSC;
• submitted the two IPs to AbuseIPDB, which is close to useless on its own, since a single report against a shared-hosting IP moves nothing until others pile on, but it costs a minute and the pile-on has to start somewhere.

If any of them come back with something worth knowing, I will update this post.

Closing

The technical sophistication is zero: shared PHP hosting, three cheap domains, a stolen brand, scraped photos, an off-the-shelf chat widget.

The design is good. Not the web design, which is the usual AI slop of stock badges and a hero image nobody chose. The design of the scam. The operator identified the objection that stops a victim (“why would I send money for a flat I have not seen?”) and answered it with escrow, which is the correct answer, then implemented a transfer to a mule. Someone who pays here is not being reckless; they are reasoning correctly from premises manufactured for them, under time pressure, in a market that has trained them to move fast or lose out.

Which is why “be careful” is not advice. The defence that works does not depend on judgment: no money moves before you have stood inside the apartment and signed a lease. In Switzerland the law goes a step further, since even after signing the deposit does not go to the landlord at all, but into an account in your own name. If the process cannot accommodate that, the process is the scam.

The details are local. Deposit caps, blocked accounts and who holds the money differ from country to country, so the version of that rule you should apply is your own market’s, not mine. What travels is the older rule the whole thing rests on: if an offer looks too good to be true, it almost certainly is.

Appendix: Kimi took it from the link onwards

I handed the exploration over to Kimi K3 Swarm with a one-line prompt:

I’m being scammed in this email thread. Can you look at that page and possibly understand what’s the payment processor and how they’re scamming people for money?

It registered a bait account, walked register.php → book.php → payment.php, pulled the IBAN off the payment page, resolved the hosting, and came back with most of what this post says, in one pass, without me specifying any of it.

I am describing what the operation does, not who runs it. The persona is fake by construction; the only real-world identities involved are the hosting account and the receiving bank account.
