London BTL Yields vs the 7.7% Break-Even: Why Serviced Accommodation Wins

The Number That Changes Everything for London Landlords

A recent analysis from This Is Money put a precise figure on what many London landlords have felt in their bones for years: you now need a 7.7% gross yield just to break even on a buy-to-let property. Not to profit. Just to avoid losing money each year.

Let that sink in for a moment. London's average traditional BTL yield hovers somewhere between 3.5% and 5%, depending on the borough. That means the majority of London landlords on standard assured shorthold tenancies are actively subsidising their tenants' housing out of their own pockets, month after month.

The culprit is a toxic combination of higher mortgage rates, the Section 24 tax changes that removed mortgage interest relief, rising insurance premiums, maintenance costs, and the growing regulatory burden of being a landlord. The question is no longer "is my property profitable?" For most traditionally let London properties, the honest answer is no. The real question is: what do you do about it?

A Quick Breakdown: Where the 7.7% Comes From

The 7.7% threshold accounts for the true cost of ownership in 2026. Here is a simplified version of the maths for a £500,000 London property with a 75% LTV mortgage at 5.5%:

| Cost Category | Annual Cost | | - -| - -| | Mortgage payments | £20,625 | | Insurance | £1,200 | | Maintenance (est. 1%) | £5,000 | | Void periods (est. 4 weeks) | Variable | | Letting agent fees (10%) | Variable | | Tax (post Section 24) | Variable |

To cover all of that and land at zero profit, you need roughly £38,500 in gross annual rent, which is 7.7% of your £500,000 property value. On a traditional AST, that £500,000 flat would need to command around £3,200 per month. In many London boroughs, that is simply not achievable for a standard one or two bedroom apartment.

How Traditional BTL and HMO Yields Compare

Traditional BTL

A standard single-let in zones 2 to 4 of London typically yields between 3.5% and 5% gross. After all costs, most landlords are running at a net loss, particularly higher-rate taxpayers who are hit hardest by Section 24. The model only works now if you bought years ago with a tiny mortgage or if you are banking entirely on capital appreciation.

HMO (House in Multiple Occupation)

Converting a property into an HMO can push gross yields to 7% or even 9% in some cases. However, the trade-offs are significant. You need an HMO licence from your local council, mandatory fire safety upgrades, regular inspections, and the management intensity is dramatically higher. Tenant turnover in rooms tends to be faster, void risk is room-by-room rather than whole-property, and councils in boroughs like Newham and Tower Hamlets have introduced additional licensing schemes that add cost and complexity. It can work, but it is a full-time operation, not a passive investment.

Serviced Accommodation and Corporate Lets: Clearing the Hurdle

This is where the maths start to tell a very different story.

A well-located London one-bedroom apartment that might achieve £1,800 per month on a traditional AST can generate £120 to £180 per night as a serviced apartment. Even at a conservative 75% occupancy rate and an average nightly rate of £130, that same property brings in approximately £3,510 per month, or around £42,120 annually.

On a £500,000 property, that is a gross yield of 8.4%, comfortably above the 7.7% break-even threshold.

For corporate lets, where companies book furnished apartments for relocating employees or project teams on stays of one to six months, the numbers are even more compelling. Corporate tenants pay a premium for quality, flexibility, and convenience. Nightly equivalent rates are often 20% to 40% above standard Airbnb pricing, occupancy tends to be higher because bookings are longer, and the wear and tear on your property is typically lower because corporate guests treat the space professionally.

Why the Yield Gap Exists

The premium in serviced accommodation comes from three structural advantages that traditional ASTs simply cannot offer:

1. Flexibility pricing. Short and medium-term stays command higher per-night rates because guests are paying for convenience, furnishing, bills included, and no long-term commitment.
2. Dynamic revenue management. Unlike a fixed monthly rent, pricing adjusts to demand. Events, seasonal peaks, and local demand spikes all flow directly into higher income.
3. Multiple revenue streams. Cleaning fees, early check-in charges, and premium positioning on platforms like Booking.com and Airbnb all contribute to the overall yield.

What Landlords Need to Know Before Repositioning

Serviced accommodation is not a magic wand. There are real considerations to address before making the switch.

Planning and regulation. In many London boroughs, the 90-day short-term let rule applies under the Greater London Council (General Powers) Act 1973. Properties let for more than 90 nights per year on a short-term basis may need planning permission for change of use. However, this rule applies specifically to lets of fewer than 90 consecutive nights. Corporate lets and medium-term bookings of 90 nights or more are not caught by this restriction, which is one reason the corporate serviced accommodation model is so attractive in London.

Lease and freeholder restrictions. If your property is leasehold, check the terms carefully. Some leases prohibit short-term letting or require freeholder consent.

Furnishing and setup costs. A serviced apartment needs to be fully furnished to a high standard, with quality linens, a equipped kitchen, fast Wi-Fi, and a professional listing with strong photography. The upfront investment is real, typically between £3,000 and £8,000 depending on the property.

Ongoing management intensity. Guest communications, check-ins, cleaning coordination, laundry, maintenance responses, listing optimisation, pricing adjustments. Running a serviced accommodation operation properly is a genuine business, not a side hustle. This is precisely where most landlords either burn out or leave money on the table.

The Simplest Path to Clearing 7.7%

Here is the honest truth. You could manage all of this yourself. Many landlords try. Some succeed for a while before the operational grind catches up with them.

Or you could hand the entire operation to a specialist management company like Airhosts and turn your underperforming BTL into a genuinely profitable, fully hands-off investment.

Airhosts manages the complete lifecycle of your serviced accommodation property across London. That means professional photography and listing creation, dynamic pricing that responds to market demand in real time, 24/7 guest communications, vetted cleaning teams, linen management, maintenance coordination, and full regulatory compliance. You receive a monthly income statement and a bank transfer. That is the extent of your involvement.

The properties that Airhosts manages routinely achieve gross yields of 8% to 12%, well above the 7.7% threshold that makes traditional BTL unviable. And because the company specialises in both short-term Airbnb lets and longer corporate bookings, your property benefits from a blended strategy that maximises occupancy year-round while staying fully compliant with London's regulations.

The Bottom Line

The 7.7% break-even number is not going away. If anything, with interest rates stabilising at higher levels and regulatory costs continuing to rise, the hurdle will only get tougher. London landlords who stick with traditional ASTs are, in most cases, choosing to lose money. Those who reposition toward serviced accommodation and corporate lets are choosing to get paid properly for the asset they own.
