Landlord Yields Hit 9%: Why Guaranteed Rent Isn't the Best Way to Capture Them

Yields Are Climbing, But the Strategy Behind Them Is Cracking

A recent report from Property Wire highlights a striking trend: landlords who choose to hold their portfolios rather than sell are now seeing yields climb as high as 9%. With 57% of landlords reportedly considering an exit, the supply vacuum is creating intense tenant demand and pushing rents upward for those who stay.

On the surface, this sounds like a golden age for buy-to-let. But dig a little deeper and the picture gets complicated fast. Those headline yields are overwhelmingly being generated through traditional Assured Shorthold Tenancies (ASTs) and Houses in Multiple Occupation (HMOs), both of which are now under serious legislative pressure. For London landlords in particular, the question isn't whether yields can reach 9%. It's whether the strategies producing those numbers are sustainable, or whether they're quietly setting landlords up for a painful correction.

Let's unpack what's really going on, examine guaranteed rent as one popular response, and explore why the maths increasingly points toward a different model entirely.

Where the 9% Yield Is Actually Coming From

The conditions creating these headline numbers are specific, and worth understanding clearly.

First, the supply vacuum. Tens of thousands of landlords have exited the private rented sector since Section 24 tax changes began biting. Every landlord who sells removes a rental property from the market, tightening supply further and allowing remaining landlords to push rents higher.

Second, tenant desperation. In many parts of the UK, tenants are competing fiercely for a shrinking pool of homes. This is especially acute in London, where demand has always outstripped supply.

Third, there's a significant regional skew. Many of the highest reported yields come from northern cities and HMO configurations where purchase prices are low relative to rental income. Replicating 9% gross yield in Zone 2 or Zone 3 London through a standard AST is, frankly, almost impossible once you factor in current property values.

For London landlords, these numbers can be misleading. The yield story is real, but it belongs to a very particular set of circumstances that most London portfolios simply don't share.

Guaranteed Rent: The Promise and the Problem

Guaranteed rent schemes have become an increasingly popular fallback for London landlords who want predictable income without tenant management headaches. The premise is simple: a company leases your property, pays you a fixed monthly rent regardless of occupancy, and handles everything from tenant sourcing to maintenance.

Sounds appealing. And for some landlords, it has worked well enough in the past. But in late 2026, the cracks are widening.

The Renters' Rights Act Squeeze

The Renters' Rights Act has fundamentally changed the risk profile for guaranteed rent operators. Tribunal rent caps mean that operators who sublease properties to tenants can no longer rely on unchecked rent increases to maintain their margins. When the operator's margin shrinks, that pressure flows directly back to the landlord in the form of lower guaranteed rent offers at renewal, or contracts simply not being renewed at all.

The PRS Database Compliance Burden

The upcoming Private Rented Sector Database adds another layer of administrative cost and regulatory exposure. Every property must be registered, every compliance standard documented. Guaranteed rent operators pass these costs through, and landlords who assumed "guaranteed" meant "worry free" are discovering that their net returns keep getting nibbled away.

What Landlords Actually Receive

Here's the uncomfortable truth about most guaranteed rent schemes in London: the rent you're guaranteed is typically 15% to 25% below market rate. That's the operator's margin. When you then subtract mortgage costs, insurance, service charges, and the compliance burden, many London landlords on guaranteed rent are netting 3% to 5% at best. That's a long way from 9%.

Stress Testing the Numbers for London

Let's run a quick scenario. Take a two-bedroom flat in South London valued at £450,000.

With a guaranteed rent scheme, you might receive £1,600 per month. After mortgage payments, service charges, insurance, and compliance costs, your net annual income could sit around £7,000 to £9,000. That's a net yield of roughly 1.5% to 2%.

Now consider the same property operated as a professionally managed serviced accommodation unit. Nightly rates for a well-presented two-bed in South London can range from £120 to £180 depending on season and location. Even at a conservative 75% occupancy rate, gross revenue can reach £3,200 to £4,000 per month. After management fees and running costs, net income can comfortably exceed £18,000 to £24,000 annually.

The difference is stark. And it explains why more London landlords are pivoting away from guaranteed rent toward short-term let management with companies like Airhosts.

Why Short-Term Let Management Changes the Equation

The objection landlords often raise is fair: "Short-term lets sound like a lot of work." And if you're self-managing, they absolutely are. Guest communications, cleaning turnovers, dynamic pricing, listing optimisation, key exchanges, linen management, and regulatory compliance all add up to what is essentially a hospitality business.

That's precisely why the model only works at scale when paired with professional management.

With a company like Airhosts handling the full operation, landlords get the upside of serviced accommodation yields without the operational burden. The property is professionally photographed, listed across multiple platforms, dynamically priced to maximise revenue, and managed end to end. Guests are screened, turnovers are handled, and compliance is maintained.

Critically, this model is not subject to the same tribunal rent caps that are squeezing AST and guaranteed rent returns. Short-term lets operate in the hospitality space, where pricing is market driven and responsive to demand. During peak periods, a well-managed London property can generate more in a single week than a guaranteed rent scheme pays in a month.

The Regulatory Landscape Favours Professional Operators

London's short-term let regulations, including the 90-day rule for entire properties, require careful navigation. The proposed tourist levy adds another consideration. But these regulations are far more manageable with a professional operator who understands the framework and builds compliance into the service.

In fact, increasing regulation actually benefits landlords who work with established management companies. As amateur hosts are pushed out by compliance complexity, professionally managed properties capture a larger share of demand and command stronger rates. Airhosts has been operating in this environment for years and has built systems specifically designed to maximise returns within London's regulatory framework.

The Bottom Line for London Landlords

The 9% yield headlines are real, but they belong to a strategy and a geography that most London landlords can't access through ASTs or guaranteed rent. Chasing those numbers through traditional channels means accepting below-market rents, growing compliance costs, and an increasingly hostile regulatory environment.

The landlords who are actually achieving strong, sustainable yields in London are the ones who have recognised that serviced accommodation, professionally managed, represents a fundamentally better use of their assets.
