BTL Purchases Fell 15% — But HMO Investors Are Doing the Opposite
The Numbers Everyone Is Misreading
UK Finance and Moneyfacts published Q1 2026 data that sent the usual wave of 'landlords are fleeing' headlines across the property press. On the surface, the story writes itself: new BTL purchase loans fell 14.9% year-on-year, landing at roughly 16,800 completions in Q1 2026. Stamp duty surcharges, the Renters' Rights Act, higher mortgage costs — the narrative practically assembles itself.
But read the same dataset differently and a different story emerges. Total new BTL loans across Q1 actually rose 3% year-on-year to over 58,000. Remortgages climbed 11.1% to around 39,000. That tells me the landlords still in the market aren't retreating — they're consolidating. They're holding what they have and, in a growing number of cases, they're restructuring to hold more efficiently.
The 14.9% purchase drop is real. I'm not disputing it. But it's a single-let story, not an HMO story. And conflating the two is the most expensive mistake a property investor can make right now.
What the HMO Licence Data Actually Shows
Foot Forward and Just Landlords submitted Freedom of Information requests to UK councils and the results are striking. HMO licence applications rose from 41,162 in 2018 to 57,725 in the most recent recorded period — a 40% increase over roughly six years. Edinburgh alone averages 5,158 applications per year.
Think about what that means structurally. While single-let landlords are selling up, the operators who remain are overwhelmingly moving toward the more complex, higher-yield, compliance-heavy end of the market. That's not a coincidence. That's rational capital allocation.
The operators exiting aren't the HMO operators. They're the accidental landlords — the person who inherited a flat, the couple who kept their first home when they upsized, the small portfolio holder who can't absorb another rate rise. When they sell, that stock leaves the private rental sector entirely. It doesn't get converted into shared housing. It gets bought by owner-occupiers or sits empty while planning is sorted.
So supply contracts at exactly the moment demand for shared housing is rising. Professionals priced out of city-centre flats, post-graduates who can't afford solo tenancies, key workers on NHS or council pay — they all need HMO-style accommodation. And there are fewer compliant rooms available to absorb them.
The Compliance Moat Most Operators Underestimate
Here's the position I'll defend: a fully licensed, compliant HMO in a supply-constrained market is one of the most defensible income assets in UK residential property right now. Not the easiest to run. Not the cheapest to set up. But defensible in a way that a single-let simply isn't.
When a single-let landlord sells, the next buyer is probably an owner-occupier. The rental supply is gone. When an HMO operator exits, the property either gets de-converted (expensive, slow, planning-dependent) or gets picked up by another operator — often at a price that reflects the complexity of the asset, not just the bricks. That friction keeps supply constrained even when ownership changes.
Compliance is the moat. Article 4 directions, selective licensing, mandatory HMO licensing under the Housing Act 2004 — these create barriers that protect established operators from a flood of new entrants. I know that sounds counterintuitive when you're staring at a licensing fee and a fire safety schedule. But every requirement that makes a new entrant hesitate is a requirement that keeps your occupancy rate high.
The operators I see struggling are the ones who entered the HMO space treating it like a single-let with more rooms. They under-invested in compliance, they cut corners on management, and now they're the ones selling. The ones staying — and buying — are running this like a business, not a side hustle.
What the Retreat Means for Occupancy and Yield
Supply shrinkage has a direct and fairly mechanical effect on occupancy rates. Fewer compliant rooms available means less vacancy time between tenancies. Less vacancy time means your gross yield calculation actually holds up in practice, not just on a spreadsheet.
The Renters' Rights Act — which the BTL headlines are largely blaming for the purchase drop — removes fixed-term assured shorthold tenancies and shifts to periodic tenancies. For a single-let landlord who relied on section 21 to manage void periods and problem tenants, that's a genuine operational challenge. For an HMO operator with a well-managed house and a waiting list, it changes very little. Your tenants aren't on ASTs in the same way. Your room-by-room structure already operates closer to a periodic model in practice.
I'm not saying the RRA creates no friction for HMO operators — it does, particularly around the new possession grounds and notice periods. Consider taking qualified legal advice on how your specific tenancy structure is affected. But the macro effect of the RRA on HMO demand is net positive: it makes single-let tenure less attractive for landlords, accelerating the exit of marginal stock, which tightens the supply of all rental accommodation including shared housing.
The operators who modelled their deals assuming 85-90% occupancy and are now running at 92-95% aren't lucky. They're the beneficiaries of a structural supply squeeze that the BTL exit data was quietly predicting all along.
The landlords reading the 14.9% purchase drop as a warning signal and the landlords reading it as a buying signal are looking at the same data. The difference is what they think the market is selecting for. My read: it's selecting for operators who can handle complexity, carry compliance costs, and manage at a professional standard. The amateur end of the market is being priced and regulated out. That's not a threat to serious HMO investors. That's the market doing their marketing for them.
