Have you ever wondered what it feels like to watch a once-lucrative venture crumble under the weight of new rules and rising costs? That’s the reality for thousands of small-scale landlords in the UK right now. The buy-to-let (BTL) market, once a golden ticket for passive income, is seeing a seismic shift. Data suggests nearly 100,000 landlords might exit the market by the end of 2025, driven by a cocktail of tax hikes, regulatory changes, and economic pressures. As someone who’s followed property trends for years, I can’t help but feel this is more than just a blip—it might signal the end of an era for the amateur landlord.
The Buy-to-Let Market: A Shifting Landscape
The UK’s rental market has long been a cornerstone of wealth-building for everyday investors. But lately, it’s starting to feel like the ground is giving way. Brokers report that 93,000 landlords with buy-to-let mortgages—roughly 6% of the total—are poised to sell their properties this year alone. That’s on top of the 65,000 who already left between 2023 and 2024. What’s driving this mass departure? It’s not just one thing—it’s a perfect storm of financial and legislative changes making the BTL game less appealing, especially for those with just one or two properties.
The rental market is losing landlords at an alarming rate, and the pace is only picking up.

Let’s break it down. The numbers paint a stark picture: in 2023, the UK had around 2.84 million unincorporated landlords, with about 57% of them holding BTL mortgages. That’s roughly 1.62 million landlords relying on borrowed funds to keep their rental businesses afloat. But with costs climbing and profits shrinking, many are asking, Is it still worth it?
Tax Changes: The Biggest Culprit
Taxes have always been a thorn in the side of landlords, but recent changes have turned that thorn into a dagger. One of the most significant blows came with the phased removal of mortgage interest tax relief. Once upon a time, landlords could deduct their full mortgage interest from their rental income before paying tax. Now? They’re stuck with a measly 20% tax credit on those payments. For someone with a modest portfolio, that’s a massive hit to their bottom line.
Then there’s the stamp duty surcharge. If you’re buying a second home in England, you’re slapped with an extra 5% on top of the standard stamp duty rate. In Scotland, it’s even worse—8% under the land and buildings transaction tax. These surcharges don’t apply to larger portfolios (six or more properties), so bigger players can dodge the bullet. But for the small landlord, it’s another reason to think twice about staying in the game.
Tax changes have made it nearly impossible for small landlords to turn a profit without raising rents sky-high.

And here’s the kicker: there’s talk of landlords being hit with National Insurance on rental profits. If that goes through, it could raise £2 billion for the government but deliver a knockout punch to the BTL sector. I’ve seen enough tax hikes in my time to know this could push even more landlords out the door.
Regulation Overload: The Renters Reform Bill
It’s not just taxes—new regulations are piling on the pressure. The Renters Reform Bill has been a hot topic, especially its plan to scrap no-fault evictions. On one hand, this protects tenants from sudden displacement. On the other, it leaves landlords feeling like they’ve lost control over their own properties. Imagine investing your life savings into a rental, only to find you can’t easily reclaim it if things go south. That’s a tough pill to swallow.
Other rules, like stricter energy efficiency standards and rising compliance costs, aren’t helping. For landlords with small portfolios, these changes can feel like death by a thousand cuts. Larger companies, often operating through limited company structures, can absorb these hits. But the accidental landlord—someone who inherited a property or bought one as a side hustle—often can’t.
- Higher taxes: Mortgage interest relief cut and stamp duty surcharges.
- New regulations: Renters Reform Bill and energy efficiency rules.
- Rising costs: Compliance and maintenance expenses eating into profits.
It’s no wonder so many are throwing in the towel. But here’s where it gets tricky: as landlords exit, the supply of rental properties shrinks. And when supply drops, rents soar. Tenants are already feeling the pinch—how much worse could it get?
The Capital Gains Tax Clue
If you need proof that landlords are bailing, look at the capital gains tax (CGT) numbers. Recent data shows a doubling in taxpayers paying CGT on residential properties over the past seven years. Since primary homes are exempt from CGT, this spike points directly to landlords cashing out. The Treasury’s seeing a nice boost in revenue, but as one expert put it, this could be a short-lived windfall if the exodus continues.
The surge in capital gains tax receipts is a clear sign that small landlords are selling up in droves.

Why are they selling? For many, it’s simple math. With higher interest rates squeezing mortgage affordability and a sluggish property market limiting capital growth, the numbers just don’t add up anymore. I’ve always thought property was a long game, but when the rules keep changing, even the most patient investors start to waver.
A Silver Lining? Falling BTL Rates
It’s not all doom and gloom. There’s a glimmer of hope in the form of lower buy-to-let mortgage rates. As of 2025, average two-year fixed rates have dropped to 4.88%, and five-year fixes are at 5.21%—the lowest since September 2022. Plus, the number of BTL mortgage products has hit a record 4,597, giving landlords more choice than ever.
| Mortgage Type | Average Rate (2025) | Change Since 2023 |
| Two-Year Fixed | 4.88% | Down from 6.64% |
| Five-Year Fixed | 5.21% | Up from 3.20% (2020) |
These lower rates could tempt some landlords to refinance or even enter the market. But here’s the catch: with tax changes and regulatory uncertainty, even cheaper financing might not be enough to keep small players in the game. As one finance expert noted, the cost of borrowing is just one piece of a much bigger puzzle.
The Ripple Effect: Tenants and the Housing Crisis
Here’s where things get messy. As landlords sell up, the rental market tightens. A recent survey found that 26% of landlords sold at least one property in 2024, while only 8% bought. Less supply means higher rents, and tenants are already struggling with affordability. If the government adds National Insurance to rental profits, landlords might pass those costs on, pushing rents even higher.
I can’t help but wonder: is this the tipping point for the UK’s housing crisis? Fewer rental properties could exacerbate homelessness and strain social housing systems. It’s a vicious cycle—landlords leave, rents rise, and tenants bear the brunt. Maybe it’s time to rethink the policies driving this exodus.
Landlords exiting the market could push rents to unsustainable levels, deepening the housing crisis.

Could Incorporation Save Landlords?
Some landlords are fighting back by restructuring their businesses. Holding properties in a limited company can shield them from the worst tax changes, like the mortgage interest relief cut. It’s a smart move for those with larger portfolios, but for the small landlord with one or two properties, the costs and complexity of incorporation often outweigh the benefits.
- Incorporate: Set up a limited company to hold properties.
- Tax benefits: Deduct mortgage interest before calculating tax.
- Downside: Higher setup costs and administrative burden.
One expert suggested revisiting mortgage interest relief rules to level the playing field. Instead of piling on more taxes, allowing landlords to deduct interest before calculating income tax (and maybe even NI) could keep smaller players in the market. It’s a fairer approach, but will policymakers listen?
What’s Next for the Buy-to-Let Market?
The future of buy-to-let feels like a coin toss. On one side, lower mortgage rates and more product choices offer a lifeline. On the other, taxes, regulations, and economic uncertainty are pushing small landlords to the edge. I’ve always believed property investment is about playing the long game, but when the rules keep shifting, it’s hard to stay committed.
The data doesn’t lie: 11% more repossessions in 2024 compared to the previous year, and a record number of landlords selling off properties. If the government doesn’t ease up on the tax and regulatory pressure, we could see the rental market dominated by big corporations, leaving small investors—and tenants—in the dust.
So, what’s the takeaway? If you’re a landlord, now’s the time to crunch the numbers and weigh your options. If you’re a tenant, brace for higher rents. And if you’re thinking about jumping into BTL, tread carefully—this isn’t the market it used to be.
Final Thoughts: Is the Amateur Landlord Era Over?
Perhaps the most sobering part of this whole saga is what it means for the average person. The buy-to-let market was once a way for regular folks to build wealth and secure their financial future. Now, it’s starting to feel like a playground for big players with deep pockets. As small landlords exit in droves, I can’t shake the feeling that we’re losing something vital—a piece of the dream that made property investment so appealing in the first place.
Will the government step in to stem the tide, or will they double down on policies that push small landlords out? Only time will tell. For now, the numbers tell a story of a market in flux—and it’s one worth watching closely.
