Property Investment Guide: Buy-to-lets

Being a landlord and investing in property can be rewarding, but it isn’t always easy. 

If you are looking to buy a medium to long-term buy-to-let investment, you first need a clear plan, a solid buy-to-let property, and an understanding of the legal and financial commitments that come with it.

In this article, we’ll find out if buy-to-lets are a good investment, what a property investment strategy is, the laws and restrictions around buy-to-lets, if letting agents are beneficial to investors, and how to buy a buy-to-let property.

Are buy-to-let properties a good investment?

In short, buy-to-lets are a great investment, but they’re not automatically successful.

If you are investing in a buy-to-let, you need to approach it as a long-term business plan, with an effective property investment strategy.

In many parts of the UK, there remains strong demand for rental homes, particularly where housing supply is tight, and affordability for buyers is out of reach, which supports both steady rents and ongoing investor interest.

However, the housing sector has changed significantly compared to a decade ago. Tax reliefs that once made buy-to-let very generous have been scaled back, interest rates and costs of financing are higher, and regulatory responsibilities for landlords have increased. 

That means margins can be tighter, and profitability isn’t guaranteed unless you plan carefully.

What is a property investment strategy?

A property investment strategy is a structured plan that outlines what you’re buying, why you’re buying it, and how it will help you achieve your goals.

Rather than purchasing a property based on emotion or short-term trends, a strategy focuses on long-term outcomes, whether that’s generating monthly income, building equity over time, or creating a balanced portfolio.

A property investment strategy should highlight:

• Objectives
• Target locations
• Property types
• Financial structure
• Exit plan

Different strategies will suit different investors.

Someone seeking a steady monthly income may focus on high-yield rental areas, where an investor looking for long-term wealth creation may look for locations with strong projected capital growth.

The laws and restrictions around buy-to-let investments 

Investing in buy-to-let property isn’t just about finding the right property and securing a mortgage; it also means understanding the legal responsibilities that come with being a landlord.

Over the past decade, regulation in the private rental sector has increased significantly. As a result, buy-to-let should be approached as a regulated business, not a passive side investment. To keep up-to-date on recent changes, here is a guide on the updated renters’ reform bill.

These are some of the key areas investors need to be aware of:

Landlord’s legal responsibilities

Landlords are legally responsible for ensuring their property is safe and compliant. This includes:

• Annual Gas Safety Certificates
• Valid Electrical Installation Condition Reports (EICR)
• Smoke and carbon monoxide alarms
• Meeting minimum Energy Performance Certificate (EPC) requirements
• Protecting tenant deposits in a government-approved scheme
  

Failure to meet these obligations can result in fines and restrictions on serving notice.

Licensing requirements

Depending on the property type and location, you may need:

• HMO licensing (for Houses in Multiple Occupation)
• Selective or additional landlord licensing (introduced by some local authorities)
  

It’s essential to check local council rules before purchasing, as licensing can impact costs and suitability.

Tax changes

Buy-to-let taxation has changed in recent years. 

Mortgage interest relief is now restricted, stamp duty includes an additional surcharge for investment properties, and rental income is subject to income tax. Capital Gains Tax may also apply when you sell.

Understanding how these rules affect your projected returns is key to assessing overall profitability.

Tenant rights and notice periods

Legislation around tenant protections continues to change, with reforms proposed and implemented in recent years affecting notice periods and possession processes. 

This makes it crucial for investors needing to stay informed, as these changes can impact flexibility and timelines.

Are letting agents beneficial for buy-to-let investments?

Whether a letting agent is beneficial purely depends on how involved you want to be. 

Managing a buy-to-let property isn’t just about collecting rent. It includes marketing the property, referencing tenants, drafting agreements, organising maintenance, staying compliant with legislation and handling any issues that arise during the tenancy. 

For some landlords, especially those with full-time careers or multiple properties, this can quickly become time-consuming.

With a letting agent, this is all covered for you. 

A good letting agent should provide:

• Accurate rental valuations based on current local demand
• Professional marketing to minimise void periods
• Tenant sourcing and referencing
• Rent collection and arrears management
• Ongoing property management, including maintenance coordination
• Compliance support to help you meet legal obligations
  
  

For investors who live far from their property, new to buy-to-lets, or prefer a more hands-off approach, a letting agent can reduce your stress and protect long-term returns. 

How do you buy a buy-to-let property?

Buying a buy-to-let property follows a similar process to purchasing a residential home, but with a few important differences.

Because you’re buying a property as an investment, lenders, affordability assessments and financial planning are all approached slightly differently.

Here’s the process of buying an investment property:

1. Define your investment criteria

Before viewing properties, be clear on your objective. Are you targeting rental income, long-term capital growth, or both? 

Your strategy will influence the location, property type and price range you focus on.

2. Review your finances

Most buy-to-let mortgages require a larger deposit than residential purchases, often 20–25% or more. 

Lenders will assess the projected rental income to ensure it comfortably covers the mortgage payments, usually by a set percentage buffer.

You’ll also need to factor in stamp duty (including the additional property surcharge), legal fees, valuation costs and contingency funds.

3. Secure a mortgage agreement in principle

Obtaining an agreement in principle from a buy-to-let lender gives you clarity on your borrowing capacity and strengthens your position when making offers.

4. Find and assess the right property

When evaluating a property, you should consider the local rental demand, the comparable rental values in the area, your expected yield and projected returns, ongoing maintenance costs, and growth potential in the area.

Strong fundamentals matter more than short-term trends.

5. Make an offer and instruct a solicitor

Once your offer is accepted, you’ll need a solicitor to handle the legal process, searches and contracts. 

The lender will arrange a valuation, and the mortgage will move toward formal approval.

6. Completion and preparation for tenants

After completion, you’ll need to ensure the property meets all legal requirements before letting, including safety certificates, EPC compliance and deposit protection arrangements.
