Encourage Landlords to invest
A Deep Dive into Returns, Taxation, and Investment Alternatives

Over the past decade, the UK’s private rental sector has seen a steady exodus of small-scale landlords. What was once a dependable route to long-term financial security or passive income has, for many, become a regulatory and financial headache. Rising interest rates, tightening regulations, and punitive tax treatment are driving many landlords to reconsider their position. When compared with alternative investments and the more favourable tax regimes offered to other small business owners, the reasons for this exodus become starkly clear.

Shrinking Returns: Buy-to-Let No Longer What It Once Was

Rental Yield vs. Capital Growth

Traditionally, landlords could expect to earn both from rental yields (typically 3–6% annually) and long-term capital appreciation. But in many areas, property price growth has stagnated or even reversed, especially with interest rate hikes dampening buyer demand. Meanwhile, rent increases have not always kept pace with rising costs, particularly mortgage repayments.

Mortgages & Rising Interest Rates

One of the most significant financial shifts has been the increase in interest rates. With many landlords on variable or fixed-rate products that have now expired, their mortgage costs have surged, in some cases doubling or tripling. These cost pressures have eaten into cash flow, pushing some landlords into negative income territory.

Unfavourable Tax Treatment: Landlords vs. Other Small Businesses

Perhaps the most critical factor behind the landlord exodus is taxation. Compared to sole traders and partnerships in other sectors, landlords operate under a distinctly harsher regime.

1. Section 24: No Mortgage Interest Deduction

Since the phased introduction of Section 24 (completed in 2020), landlords can no longer deduct mortgage interest from their rental income. Instead, they receive a 20% tax credit on interest costs. For higher-rate taxpayers, this effectively results in taxation on phantom profits — income they never actually received.

By contrast, other small businesses — whether operating as sole traders, partnerships, or limited companies — can deduct legitimate finance and operational costs, including interest on loans, before calculating taxable profit.

2. No Allowance for Personal Use or Flexibility

Unlike many businesses where family involvement can justify salaries or expense allocations, landlords face limitations. Even though managing property is a very time-consuming process, landlords can’t claim deductions for their time spent managing properties unless structured through a formal letting agent or incorporated business.

3. Capital Gains Tax (CGT) Inefficiencies

While other small businesses may benefit from Business Asset Disposal Relief (formerly Entrepreneurs’ Relief), reducing CGT to 18% on the first £1 million of gains, residential landlords do not qualify unless their property is a furnished holiday let. Landlords typically pay 18/28% CGT, depending on their income level.

4. Incorporation Challenges

While incorporating a buy-to-let business can offer tax benefits (such as full mortgage interest deductibility and lower corporation tax), transferring personally owned properties into a company usually triggers both Capital Gains Tax and Stamp Duty Land Tax, creating a prohibitive upfront cost.

Alternative Investments: More Attractive and Flexible Options

With real returns dwindling and tax burdens rising, many landlords are now looking elsewhere.

Stock Market and ETFs

• Liquidity: Shares can be bought and sold quickly.
• Tax Efficiency: Investments in ISAs and SIPPs grow tax-free.
• No Direct Management: Passive income with none of the headaches of property maintenance or responsibilities for tenants.
• Consistent Returns: Long-term equity markets historically return 6–8% annually, comparable to or better than many buy-to-let investments without the illiquidity.

Business Ownership and Self-Employment

• Tax Deductibility: Business expenses, including premises, equipment, and even vehicles, are often deductible.
• Profit-Sharing: Partnerships can distribute profits more flexibly.
• Retirement and Exit Options: Business assets can qualify for tax reliefs and succession planning tools that property assets often do not.

Regulation, Compliance, and Risk

Finally, the regulatory burden on landlords continues to grow. From EPC upgrades to stricter eviction rules and licensing schemes, the legal environment is far more complex than a decade ago. Unlike most small businesses, landlords must comply with a tangle of housing, safety, and tax rules — often at their own cost and risk.

Conclusion: The Cost-Benefit Equation No Longer Adds Up

When landlords compare the returns from property against alternative investments — and especially when they consider how much more harshly they’re taxed than other sole traders or partnerships — it becomes evident why many are choosing to exit the market. Property remains a long-term asset class with value, but as an investment for small, private landlords, it’s no longer the attractive proposition it once was.

Unless tax parity is restored and regulation simplified, the flight of landlords is likely to continue, with consequences not just for investors, but for tenants and the broader housing market as well.
