Fraudsters are targeting your luxury rentals. Here’s how to stop them.

A £1,000-a-month studio in a London suburb and a £12,000-a-month penthouse in Mayfair follow the same tenant referencing playbook.

Yet the latter is far more likely to fall victim to tenancy fraud.

According to Goodlord's data, the confirmed fraud rate for properties renting above £10,000 a month is around 20 cases per 1,000 applications. This is about three to six times higher than the average.

Targeting these properties is a simple way for fraudsters to maximise their yield without increasing the risk they take on.

So how do agencies with luxury portfolios level the playing field?

In this blog, we’ll uncover the tactics fraudsters use to slip through your referencing process and reveal what you can do to strengthen your defences.

Why do high-value rental properties attract fraud?

Bypassing a modern referencing process now requires serious capital, meticulous planning, and sophisticated technology. Fraudsters do not invest that kind of effort to secure a standard one-bed flat. They put their investment where the returns are highest.

What this investment buys them is a “multi-layered synthetic identity.” A fake employer reference sits alongside a convincing payslip; that payslip matches an altered bank statement; the bank statement supports an entirely invented employment history.

This level of orchestration only makes financial sense against a large enough prize. A single successful application on a £15,000-a-month property hands a fraudster months of occupation, control of a high-value asset, and, in the more organised cases, a base for illegal subletting or short-let exploitation.

Put simply, the bigger the prize, the more sophistication it's worth deploying to get it.

Why is risk heightened in major cities?

Fraud doesn't spread evenly across the map. It clusters where the money is. If the luxury lettings trap is built on criminals chasing the highest possible return on investment, it is no surprise that it strikes hardest where premium stock is most densely concentrated.

Goodlord’s report puts the UK’s top three tenancy fraud hotspots at Greater London (6.7 cases per 1,000 applications), the West Midlands (3.5, driven by Birmingham) and the North West (3.4, driven by Manchester and Liverpool).

All three combine a high concentration of premium assets with a fiercely competitive, fast-moving rental market. In major urban hubs, agencies are under immense pressure to process applications and secure tenancies quickly. Organised fraud networks use that operational speed as a smokescreen, relying on market urgency to slip synthetic identities past standard visual checks.

For an enterprise agency, regional exposure and property value do not just add up — they multiply. A multi-branch agency with offices in London, Birmingham, and Manchester manages both 'hotspot risk' and 'premium risk' simultaneously, facing a compounded threat on every high-value application that walks through the door.

What is the financial risk of a bad high-value let?

The average direct cost of a single fraudulent tenancy across the private rented sector is £9,601. This baseline covers legal costs, court and bailiff fees, rent arrears, void periods, and property damage.

However, that figure is merely a sector-wide average. When dealing with high-value properties, the numbers escalate at a rather frightening pace:

• Rent arrears - A missed payment on a £900-a-month studio is annoying. A missed payment on a £12,000-a-month prime asset quickly adds up to five figures within weeks.
• Possession timelines - With Section 21 gone, there's no no-fault shortcut while a fraud case is being sorted out. Section 8 proceedings already run to 15 months or more. The longer it takes, the more costs multiply.
• Escalating legal fees - Court costs do not shrink for expensive properties. Untangling a contested case, especially one involving a professional fraudster and a synthetic identity, often requires specialist (and expensive) legal intervention.
• Compliance exposure - Mandatory Anti-Money Laundering (AML) and financial sanctions checks apply to every tenancy. A sophisticated fraudster slipping through the cracks doesn’t just raise questions about the referencing decision; it extends to how the compliance checks were carried out in the first place.
• Property damage - Putting the aftermath of an illegal subletting operation right costs significantly more when replacing bespoke finishes, high-end appliances, and luxury furnishings.
• Reputational damage - A single high-profile eviction, subletting ring or illegal short-let operation running out of a managed luxury portfolio does more damage to landlord and brand trust than the same incident at the mainstream end of the market.

Ultimately, the structure of the risk is identical to the mainstream market. It’s just that on premium stock, every part of it is simply larger.

Real cases: How tenancy fraud plays out on high-value portfolios

While fraud data reveals the macro pattern, court records and investigative journalism expose what this actually looks like when it infiltrates a portfolio.

BBC Panorama’s July 2026 investigation, “There’s Gangster in My Flat,” is one such look. It followed landlords whose properties had been turned into a drugs factory, a brothel, and a ransacked, illegally sublet flat. The terrifying common denominator? In every instance, the applicant appeared entirely credible and had sailed right through standard checks conducted by reputable letting agents.

In another case in Central London, a landlord discovered a double subletting arrangement running under what looked like an entirely standard tenancy agreement. By the time it came to light, the original tenant had built up close to £17,000 in rent arrears. Now, apply that scenario to a high-value portfolio. On a £12,000-a-month property, that's less than six weeks of rent, before legal and court costs are even added.

For an enterprise agency managing high-value stock, it proves that the threat is live, and that traditional defence mechanisms are simply no longer fit for purpose.

Building a defence that matches the threat

Manual document review was never built to catch a synthetic identity engineered to withstand it, and it's least equipped to catch one at the premium end of the market, where fraudsters have the most capital and motivation to get the details right.

The defence has to match the sophistication of what it's up against, which means layering three checks rather than leaning on any one of them.

• Identity Document Validation Technology (IDVT) - Biometric AI, liveness analysis and police database checks confirm the person applying genuinely matches their documents.

• Open Banking - Verifying income and affordability directly from the applicant's bank data, rather than a supplied statement that can be edited or generated with AI.

• HMRC and direct-to-payroll integrations - Confirming employment and income at the source, rather than through a reference that could come from a compromised or fabricated contact.

Goodlord's Trusted Sources have already helped identify over 97% of fake employment reference fraud, 98% of forged payslips, 83% of referee fraud, and over 80% of fake document fraud on its platform.

As Greg Tsuman, Managing Director of Lettings at Martyn Gerrard, puts it:

“No single check will eliminate fraud entirely. By combining multiple independent verification methods with experienced human oversight, we significantly reduce the risk of fraudulent applications progressing through the referencing process.”

How Goodlord helps

For enterprise agencies managing high-net-worth stock, fraud governance can't be left to individual branches to work out on their own. It needs a standardised, portfolio-level safety net.

Goodlord helps agencies deploy this layered defence effortlessly across their entire operation. Trusted Sources automates the heavy lifting by verifying income and employment directly through Open Banking and HMRC integrations, reducing reliance on applicant-supplied paperwork.

Additionally, by integrating Rent Protection Insurance, agencies can offer landlords an ultimate safety net, ensuring the massive financial exposure attached to premium properties is thoroughly mitigated at every stage of the tenancy.
