Rents Rising 12% by 2030: Why Mid-Term Rentals Unlock Growth That Buy-to-Let Now Cannot

A 12% Rent Rise Is Coming, But Can London Landlords Actually Capture It?

The numbers look promising on the surface. Industry forecasts project UK rents rising by approximately 12% between 2026 and 2030, driven by persistent housing supply shortages, population growth, and continued demand pressure in cities like London. For landlords, that should be welcome news.

But here is the catch. Under the Renters' Rights Act, which has reshaped the buy-to-let landscape in 2026, landlords with Assured Periodic Tenancies (APTs) can only increase rent once per year, and only to the prevailing market rate. Tenants can challenge any proposed increase at a tribunal. That means the 12% cumulative growth projected over four years will be difficult, sometimes impossible, to capture through traditional long-term lettings.

So where does that leave property investors who want their rental income to keep pace with the market? Increasingly, the answer is mid-term rentals.

What Exactly Are Mid-Term Rentals?

Mid-term rentals sit between traditional long lets and short-term holiday stays. They typically cover stays of one to six months, catering to corporate relocators, project-based professionals, medical workers on placements, families between homes, and international visitors who need more than a hotel but less than a year-long tenancy.

In London, the demand for this type of accommodation has grown significantly. Companies relocating employees, NHS trusts sourcing temporary housing, and digital professionals seeking flexible living arrangements all fuel a robust and year-round market.

Unlike an AST or the new APTs, mid-term lets are typically structured as contractual licences or short fixed-term agreements. Each booking is a fresh contract at a fresh price, which brings us to the key advantage.

How Mid-Term Lets Bypass the Structural Rental Growth Lag

With a traditional long-term tenancy under the new rules, your ability to adjust rent is constrained. You get one shot per year, and if a tribunal disagrees with your proposed figure, you could end up stuck below market rate for another twelve months.

Mid-term rentals work differently. Every time a guest checks out and a new one checks in, you reprice. If the market has moved up 3% in the last quarter, your next booking reflects that immediately. Over the course of a year, you might reprice four, six, or even eight times depending on average stay length.

This is where the compounding effect kicks in. Rather than waiting twelve months to request a single increase (and hoping it is not challenged), mid-term landlords capture incremental gains continuously. Over a four-year period where rents are projected to climb 12%, mid-term operators are positioned to match or exceed that trajectory in real time.

The Genuine Advantages for London Landlords

Higher Rental Yields

Mid-term lets in London typically command a premium of 20% to 40% over equivalent long-term rents, partly because tenants value the flexibility and furnished, move-in-ready nature of these properties.

Reduced Void Risk Through Diversified Demand

Rather than relying on a single tenant, mid-term landlords tap into multiple demand streams. Corporate bookings, insurance-funded stays, and relocation contracts all provide different channels of occupancy.

Faster Response to Market Shifts

Whether rents are rising or a seasonal dip requires a pricing adjustment to maintain occupancy, mid-term lets give you the agility to respond in days rather than months.

Fewer Regulatory Constraints Than Short Lets

Unlike nightly Airbnb-style lets, which face the 90-day rule in London, mid-term rentals of 90 nights or more per booking sidestep that restriction entirely.

The Pitfalls You Need to Watch For

Mid-term letting is not without its challenges, and any honest guide should spell them out.

Higher Turnover Costs

More changeovers mean more cleaning, more linen changes, more wear and tear inspections, and more administrative work. Furnishing costs are also higher than a standard unfurnished long let.

Consistent Marketing Required

You cannot simply list a property and forget about it. Mid-term lets require active management of listings across platforms like Airbnb, Booking.com, SpareRoom, and corporate housing portals. Pricing needs to be monitored and adjusted regularly.

Guest Vetting and Compliance

While you avoid the full weight of the Renters' Rights Act, you still need proper contracts, deposit handling, safety compliance, and insurance. Getting this wrong can be costly.

Occupancy Is Not Guaranteed

Without a long-term tenant locked in, there will be gaps between bookings. In quieter months, void periods can eat into the yield premium if pricing and marketing are not handled strategically.

For landlords who want the benefits of mid-term letting without the operational headaches, this is exactly where professional management becomes valuable. Companies like Airhosts specialise in handling every aspect of this process, from listing optimisation and dynamic pricing to guest communication and turnover logistics.

Why the Smartest Landlords Go One Step Further

Mid-term rentals are a strong strategy, but here is something worth considering. The highest-yielding approach for London property owners often combines mid-term stays with professionally managed short-term lets.

Short-term lets, when managed well, can generate 30% to 60% more than long-term rents. By blending short stays during peak demand periods with longer mid-term bookings during quieter months, landlords achieve both maximum yield and stable occupancy. This hybrid approach is something Airhosts has refined across hundreds of London properties, using data-driven pricing tools and a dedicated operations team to keep returns consistently high.

The beauty of this model is that you, the landlord, do not have to manage any of it. No late-night guest messages, no coordinating cleaners, no repricing listings at midnight. You receive your income, and a professional team handles the rest.

Comparing the Options Side by Side

Consider a London two-bedroom flat valued at £2,000 per month on a long-term let:

• Long-term APT: £24,000 per year, with rent increases limited to once annually, subject to tribunal challenge. Over four years, you might capture some of the projected 12% growth, but with structural delays and potential pushback.
• Mid-term let: £28,000 to £33,000 per year, repriced at every changeover, with full exposure to upward market movement.
• Professionally managed short-term and mid-term hybrid: £32,000 to £42,000 per year, optimised across seasons and demand patterns, fully hands-off.

The gap is significant, and it widens every year that rental growth compounds.

The Bottom Line for London Landlords

The rental market is moving in your favour, but only if your letting strategy allows you to actually capture that growth. The Renters' Rights Act has made traditional buy-to-let structurally slower at responding to rising rents. Mid-term lets solve part of that problem. A fully managed short-term and mid-term hybrid strategy solves all of it.
