London Flat Prices Drop £19K While Yields Hit 8.1%: Why Smart Landlords Are Switching to Mid-Term Rentals

London Flats Are Losing Value, and Landlords Are Feeling the Squeeze

The latest data from Fleet Mortgages paints a stark picture for London landlords. While national rental yields have climbed to an impressive 8.1% across all regions, London flat values have dropped by 1.7% over the past year. In real terms, that means the average London flat is worth roughly £19,000 less than it was twelve months ago.

For landlords who bought flats expecting steady capital appreciation to offset modest rental returns, this is a painful double hit. You're watching your asset depreciate while yields in the capital continue to lag behind the rest of the country. It's what some analysts are calling the "capital-loss-plus-yield-squeeze trap," and it's pushing a growing number of London property owners to rethink their entire letting strategy.

The question is: what can you actually do about it?

Enter the Mid-Term Rental Strategy

One approach gaining serious traction among savvy London landlords is converting underperforming flats into mid-term rental units. These are furnished properties let on stays of one to three months, targeting a very specific set of tenants who are willing to pay a significant premium for flexibility and quality.

We're talking about three core tenant groups:

• Relocation tenants who need a comfortable base while they search for permanent housing in London
• Insurance housing placements where displaced residents need temporary accommodation, often funded by insurers
• Corporate contractors and project workers on fixed assignments who need something better than a hotel but more flexible than a 12-month tenancy

These tenants don't want hostels. They don't want bland serviced apartments either. They want a real home, fully furnished and well managed, for a defined period. And they're prepared to pay 40% to 60% more than standard AST rents to get it.

Why the Premium Exists

The premium isn't arbitrary. Mid-term tenants are paying for convenience, flexibility, and speed. An insurance company placing a family needs the unit available within days, not weeks. A relocating executive wants somewhere liveable from day one, with Wi-Fi, linens, and a functioning kitchen. A contractor on a three-month assignment doesn't want the hassle of setting up utility accounts.

When you provide all of that in a well-presented London flat, you can realistically charge £2,000 to £2,500 per month for a property that might only achieve £1,400 to £1,600 on a standard AST. Over a year, even accounting for occasional gaps between bookings, the income uplift is substantial.

A Regulatory Advantage Worth Noting

There's another reason mid-term rentals are attracting landlord attention right now. The incoming Renters' Rights Act is set to reshape the long-term lettings landscape significantly, abolishing Section 21 "no fault" evictions and introducing new compliance requirements for AST landlords.

Mid-term lets that fall outside the scope of traditional assured shorthold tenancies can sidestep many of these regulatory changes. Properties let on licence agreements or as serviced accommodation operate under a different legal framework, giving landlords more control over their property and fewer bureaucratic headaches.

What You Need to Know Before Making the Switch

Mid-term rentals aren't a magic bullet, and it's important to go in with your eyes open.

The Upfront Investment

Your flat needs to be fully furnished to a high standard. Think quality mattresses, reliable broadband, a well-equipped kitchen, and tasteful décor. First impressions matter enormously in this market, and the tenants paying premium rates expect premium presentation. Budget anywhere from £3,000 to £8,000 to furnish a one or two bedroom flat properly, depending on what you already have in place.

Void Periods Are Real

Unlike an AST where you sign a tenant for 12 months and collect rent like clockwork, mid-term lets involve turnover. You might have a two-month booking, then a week's gap, then a six-week placement. Managing these gaps, keeping occupancy rates high, and ensuring smooth transitions between tenants requires active management and strong marketing across multiple platforms.

Operational Complexity

Every changeover means cleaning, linen replacement, inventory checks, and potentially minor maintenance. You'll need to handle guest communications, key handovers, and sometimes resolve issues at short notice. For a landlord used to handing keys to an AST tenant and collecting rent monthly, this is a fundamentally different workload.

Lease and Mortgage Considerations

Before converting, check your mortgage terms carefully. Some buy-to-let mortgages restrict short and mid-term letting. Similarly, if your flat is leasehold, your lease may contain clauses about the minimum length of tenancy or restrictions on serviced accommodation use. Getting this wrong can be costly, so always take professional advice first.

When Mid-Term Becomes Short-Term: The Bigger Opportunity

Here's where things get really interesting. Many landlords who explore mid-term rentals quickly realise that the same infrastructure, furnishing, and management approach also opens the door to short-term lets. And the yield difference can be even more dramatic.

Short-term lets, typically stays of a few nights to a few weeks, can generate significantly higher returns than even mid-term rentals. A well-located London flat listed on Airbnb and other booking platforms can achieve annual revenues that dwarf both AST and mid-term income, particularly in high-demand areas near transport links, business districts, or tourist attractions.

The catch? Short-term lets require even more intensive management. Pricing needs to be dynamic, adjusting daily based on demand, seasonality, and local events. Guest communications need to be rapid and professional. Cleaning and turnover must happen reliably, sometimes with just a few hours between checkout and the next arrival.

This is exactly where professional management becomes not just helpful, but essential.
