Is Buy to Let Still Worth It for Landlords and Investors?

Max Royston

There is a lot to consider, including the changes to mortgage interest tax relief, the stamp duty surcharge for second homes and the ever-increasing cost of funding. Many landlords and investors are questioning whether buy-to-let remains a profitable investment.

What is the Mortgage Interest Relief on Buy-to-Let?

In the UK, landlords can no longer deduct mortgage interest payments from their rental income to reduce their tax bill. Instead, they receive a flat 20% tax credit on their mortgage interest payments.

Previously, higher-rate taxpayers (40-45%) could deduct the full amount of mortgage interest from their rental income before calculating their tax liability. This meant they benefited from tax relief at their higher marginal rate. However, since April 2020, all landlords, regardless of their tax bracket, have received only basic rate relief of 20%, reducing the overall tax benefits for higher-rate taxpayers.

This change has levelled the playing field for lower-income landlords while significantly reducing net profits for those in higher tax brackets.

What is the Surcharge on Stamp Duty for Second Homes?

The stamp duty rates for purchasing a second home or buy-to-let property have increased, making the cost of investing in additional properties higher than before. As of October 31, 2024:

Property Value Second Home Stamp Duty Rate

Property Value	Second Home Stamp Duty Rate
Up to £250,000	5%
£250,001 – £925,000	10%
£925,001 – £1,500,000	15%
Over £1,500,000	17%

These rates apply directly to second-home purchases, replacing the standard rates applied to primary residences. The stamp duty land surcharge adds a significant upfront cost, meaning landlords must factor this into their investment calculations, as they can significantly impact the profitability of a buy-to-let investment.

If you’re reconsidering whether buy-to-let is right for you, it may be worth exploring alternative ways to maximise your property investments. The higher stamp duty rates and the Renters (Reform) Bill, combined with other rising expenses, are leading some landlords and investors to exit the market.

How do Buy-to-Let Mortgages Work?

A buy-to-let mortgage is designed for individuals purchasing property as an investment to rent out, rather than as a primary residence. These mortgages have different criteria and lending conditions compared to standard residential mortgages due to the risks associated with rental properties.

A buy-to-let mortgage differs from a standard residential mortgage in several ways:

• Higher deposit required – Most lenders require a minimum deposit of 25%, though some may accept as low as 20% or as high as 40%, depending on circumstances.

• Interest-only options – Many buy-to-let mortgages are interest-only, meaning landlords only pay the interest each month and must repay the full loan amount at the end of the term.

• Rental income requirements – Lenders typically require expected rental income to be at least 125-145% of the mortgage repayments to ensure affordability.

• Higher interest rates – Lenders charge higher interest rates on buy-to-let mortgages because they are considered higher risk, as repayments depend on rental income rather than personal earnings.

Note: Some lenders also require borrowers to own a residential property before they can take out a buy-to-let mortgage. Read our guide to find out how to convert a residential mortgage to buy to let. 

How to Work out Rental Yield?

Rental yield is a key metric when determining the profitability of a buy-to-let investment.

Formula: 

• (Annual Rental Income ÷ Property Price) × 100 = Rental Yield (%)

For example, if a property costs £200,000 and generates £12,000 in annual rent:

• Rental Yield = (£12,000 ÷ £200,000) × 100 = 6%

Most buy-to-let investors aim for a 5-8% rental yield to ensure profitability.

Takeaway: Before investing, ensure your rental income covers mortgage repayments, maintenance, and other landlord costs buy-to-let properties incur.

Best Buy-to-Let Locations in the UK?

With rising mortgage costs and tax changes, rental yields and tenant demand are key factors when assessing a buy-to-let investment. Some cities continue to offer strong rental returns, while others provide long-term capital appreciation. Below are the best UK buy-to-let locations ranked by rental yield, based on the latest market data.

• Liverpool – One of the most profitable buy-to-let locations, with rental yields of 7.5% – 10.2%. Affordable property prices (average £174,400) and high tenant demand make Liverpool an attractive option for investors.

• Manchester – With rental yields of 6.8% – 8.1%, Manchester property benefits from a booming job market, ongoing regeneration, and strong rental demand. The city remains a prime investment choice, particularly for apartments.

• Leeds – A solid buy-to-let location, offering rental yields of 6.2% – 7.7%. The average property price is £265,000, and demand is driven by a growing workforce and student population.

• Birmingham – A strong buy-to-let market with yields of 6% – 7.2%. The city attracts skilled professionals and students, and ongoing investment in infrastructure makes Birmingham flats a stable long-term investment.

• London (Zones 3-6) – Although London property prices remain high (£547,800 on average), rental demand is strong, particularly in Outer London areas like Croydon, Ilford, and Bromley. Investors can expect rental yields of 4.7% – 6.2%.

• Reading, Luton, Watford, Slough – The Commuter belt offers rental yields of 4.2% – 5.8%. While lower than northern cities, demand from professionals commuting to London makes these areas attractive for long-term capital appreciation.

Keep in mind: While higher rental yields can lead to better short-term profits, long-term capital growth, tenant demand, and local economic development should also be factored into any buy-to-let investment decision.

Buying a Buy-to-Let Property? Landlords Should Consider This.

Once you’ve identified a strong buy-to-let location, the next step is choosing the right property for your investment strategy. The type of property you buy, your management approach, and your long-term financial goals will all impact your rental income and profitability.

1. Decide on Your Target Tenant Type

Different types of tenants have varying needs, which will influence your property choice, location, and rental income potential.

• Students – Properties near universities, affordable rent, multiple bedrooms for house-sharing.
• Young professionals – Modern apartments or well-connected commuter homes with good amenities.
• Families – Larger homes with outdoor space, near schools and parks.

Understanding your ideal tenant will help you choose a property that stays in high demand, reducing vacancy periods.

2. Property Management: Hands-On or Hands-Off?

Before purchasing, decide how involved you want to be in managing the property.

• Self-management – If you’re planning to manage the property yourself, choose a location close to home for easier maintenance and tenant interactions.
• Using a letting agent – If you prefer a hands-off approach, you can invest further afield and hire a letting agent to handle tenant management, rent collection, and maintenance.

Letting agents typically charge 10-15% of the monthly rent, so factor this into your cost calculations.

3. Define Your Profit Strategy: Rental Yield vs. Capital Growth

How you make money from buy-to-let depends on whether your priority is rental income, property appreciation, or both.

• Capital growth strategy – Buying in an area with strong property price appreciation, even if rental yields are lower. This approach relies on selling the property at a higher value in the future.
• Rental yield strategy – Targeting higher rental income to generate immediate profits. Northern cities like Liverpool, Manchester, and Leeds often provide stronger yields than London.
• A balanced approach – A mix of both, often found in emerging investment hotspots where property prices are rising, but rental yields remain healthy.

Tip: Check local rental demand, property trends, and tax implications before deciding on your investment approach.

4. Consider Additional Costs & Regulations

Beyond the purchase price and mortgage repayments, buy-to-let landlords must budget for additional costs, including:

• Stamp duty surcharge – A 3% surcharge applies to second homes and buy-to-let purchases.
• Ongoing maintenance – Property repairs, refurbishments, and compliance with rental standards.
• Void periods – Covering mortgage costs when the property is vacant.
• Landlord insurance – Protection against property damage, rent arrears, and liability claims.
• Energy efficiency regulations – New EPC rules may require landlords to make properties more energy efficient to at least a C rating by 2028.

Failing to plan for these expenses can significantly impact your rental profits

A successful buy-to-let investment requires careful planning. Choosing the right tenant type, management approach, and financial strategy will help you maximise rental income and long-term property value. Make sure to factor in market trends, tax changes, and regulatory requirements before making a purchase.

Landlord Loopholes: How to Sell Your Buy-to-Let and Pay Less Tax

If you decide buy-to-let is no longer the right investment for you, there are several landlord loopholes in how to sell your buy-to-let and pay less tax.

• Private Residence Relief (PRR) – If you lived in the property before renting it out, you may be eligible for partial Capital Gains Tax relief when selling.
• Lettings Relief – Can provide up to £40,000 in tax relief (£80,000 for couples).

• Transferring to a Spouse – If your partner is in a lower tax bracket, transferring the property before selling may reduce your tax liability.
• Selling Property Through a Limited Company – Some landlords transfer properties to a limited company before selling, potentially lowering tax costs.

Takeaway: Using landlord loopholes on how to sell your buy-to-let and pay less tax can help minimise tax liabilities when selling your buy-to-let property.

In Conclusion

There is still money to be made in buy-to-let, but remember the following two key takeaways:

1. Choose a property that suits the type of prospective tenant you are looking for.
2. Opt for a city that is popular with young families, young professionals and students as they will push up demand, and therefore, the rent price.

While buy-to-let investing is still viable, rising costs and tighter regulations mean many landlords are reconsidering their investments. If you are struggling with higher taxes, mortgage costs, or stamp duty surcharges, selling a property portfolio could be the best option.
