Buy-to-Let Explained
Thinking of becoming a landlord? Welcome to our guide, buy-to-let explained. Many people consider property a reliable investment. Whether you plan to buy a single rental home or build a portfolio, understanding buy-to-let is essential.
A rental property can provide a steady income if the rent covers mortgage payments. On average, UK buy-to-let properties generate around £1,100 per month in rent. Property prices may also rise over time, offering long-term financial benefits. However, risks exist, and landlords have legal responsibilities to fulfil.
This guide covers key aspects of buy-to-let, including mortgages, tax implications, and landlord responsibilities.
What is a Buy-to-let Mortgage?
Buy-to-let involves purchasing a property with the intention of renting it out. The goal is to generate income from rent while benefiting from potential increases in property value. Landlords must also handle property maintenance and tenant management.
A buy-to-let mortgage differs from a standard residential mortgage. Instead of basing affordability on personal income, lenders assess potential rental earnings. Most lenders require a 25% deposit, though some accept lower amounts at higher interest rates. Many buy-to-let mortgages operate on an interest-only basis, meaning borrowers repay only the interest each month and clear the total loan at the term’s end.
For those without sufficient savings, securing a buy-to-let mortgage is crucial. Lenders typically require applicants to be homeowners earning at least £25,000 annually with a good credit history. Some impose age restrictions, usually capping eligibility at 70 years old.
More details on securing a buy-to-let mortgage are available in our Mortgage Guides.
How Much Can You Borrow for a Buy-to-Let Mortgage?
Unlike standard mortgages, buy-to-let lending criteria focus on rental income. Lenders usually expect rental income to be at least 125%-145% of monthly mortgage payments. For example, if a mortgage costs £800 per month, rental income should be at least £1,000.
Lenders conduct stress tests to ensure borrowers can meet repayments, even if interest rates rise. Mortgage affordability calculators can help estimate borrowing limits based on expected rental earnings.
Buy-to-Let Deposit and Fees
Most lenders require a minimum 25% deposit for a buy-to-let mortgage product. A larger deposit, often 40% or more, may provide access to lower interest rates and a wider choice of lenders. Some lenders accept smaller deposits, but these options may include higher interest rates or additional product fees.
Before applying, landlords should review the full cost of borrowing and ensure that the rental income meets lenders’ affordability and stress-testing rules. Speaking to a broker through mortgage advisers near you can help you understand which lenders suit your circumstances.
Upfront Costs to Consider
When arranging buy-to-let mortgages, landlords should budget for:
- Mortgage arrangement fees, which often range between £1,000 and £3,000.
- Stamp Duty Land Tax, including the 3% surcharge on additional properties valued above £40,000.
- Solicitor fees are typically between £800 and £1,500.
- Property surveys can cost from £250 to £1,500, depending on the type of survey.
These costs should be factored into your overall investment plan before proceeding.
Rental Yield and Investment Assessment
Rental yield is a key measure when assessing a buy-to-let property. It is calculated as:
Annual Rental Income divided by Property Value, multiplied by 100.
For example, a property valued at £200,000 that generates £14,000 in rent per year yields 7%. In many areas of the UK, yields between 5% and 7% are common, though this varies by location and property type.
Lenders will assess whether the expected rental income covers the mortgage payments, usually applying a minimum rental coverage ratio. Understanding this requirement is essential when arranging buy-to-let mortgages.
Ongoing Costs and Financial Planning
Landlords must also plan for ongoing expenses, including maintenance, letting agent or property management fees, insurance and potential void periods when the property is unoccupied. Many investors set aside contingency funds each year to cover unexpected repairs.
If you are considering expanding your portfolio or reviewing financing options, Connect Experts can help you explore suitable buy-to-let mortgages and related solutions, such as bridging finance, which provides short-term funding. For tailored guidance, you can contact Connect Experts to discuss your investment plans with an experienced adviser.
Tax Implications for Landlords
Income Tax
Rental income is subject to income tax at standard rates:
- Basic rate taxpayers (20%): Profits up to £50,270.
- Higher rate taxpayers (40%): Profits between £50,271 and £150,000.
- Additional rate taxpayers (45%): Profits over £150,000.
Landlords can deduct some expenses before calculating tax, such as:
- Letting agent fees
- Property repairs
- Landlord insurance
- Utility bills (if covered by the landlord)
Capital Gains Tax (CGT)
When selling a buy-to-let property, landlords pay Capital Gains Tax on the profit. Rates are:
- 18% for basic rate taxpayers
- 28% for higher rate taxpayers
Some allowances apply, and expenses like Stamp Duty and solicitor fees may be deductible.
More details on tax liabilities can be found on GOV.UK.
Buy to Let Mortgage Landlord Responsibilities
If you are arranging a buy-to-let mortgage product, it is important to understand your legal duties as a landlord. Meeting these obligations protects both you and your tenants, and helps avoid penalties or enforcement action.
Tenancy Agreement
Most landlords use an Assured Shorthold Tenancy agreement. This contract outlines rent, deposit terms, responsibilities and notice periods. A clear written agreement reduces disputes and supports proper property management.
Tenant Deposit Protection
If you take a deposit, it must be protected in a government-approved scheme such as MyDeposits or the Tenancy Deposit Scheme. You must also provide prescribed information to the tenant within the required timeframe. Failure to comply can lead to financial penalties and restrictions on regaining possession.
Right to Rent Checks
Before granting a tenancy, landlords in England must confirm the tenant’s legal right to rent in the UK. Proper document checks and record keeping are essential. Non-compliance can result in fines or further legal consequences.
EPC Requirements
Rental properties must hold a valid Energy Performance Certificate with a minimum rating of E, unless a registered exemption applies. Letting a property below this standard may result in enforcement action and financial penalties.
Gas and Electrical Safety
Landlords must arrange an annual gas safety inspection carried out by a Gas Safe registered engineer. An Electrical Installation Condition Report is also required at least every five years. Copies of these certificates must be provided to tenants.
Fire and Carbon Monoxide Safety
Smoke alarms must be installed on every storey of the property. Carbon monoxide alarms are required in rooms containing solid fuel appliances. Regular testing ensures compliance and tenant safety.
Protection and Risk Planning
Landlords should also consider protection insurance to help cover mortgage payments in case of illness, accident or other unforeseen events. While not compulsory, this can provide financial reassurance.

Should You Use a Letting Agent?
If you have secured a buy-to-let mortgage, you will need to decide how to manage the property. One of the first questions many landlords ask is whether they should use a letting agent or manage the property themselves.
This decision can affect your time commitment, rental income and ongoing responsibilities.
What Does a Letting Agent Do?
A letting agent can manage some or all aspects of your rental property. Services may include:
- Marketing the property
- Referencing tenants
- Preparing tenancy agreements
- Collecting rent
- Arranging maintenance
- Managing compliance documentation
If you are arranging a buy-to-let mortgage, lenders may also expect the property to be let on an Assured Shorthold Tenancy. A letting agent can help ensure the tenancy structure meets lender requirements.

Self-Management vs Using a Letting Agent
Managing the property yourself may reduce monthly costs. However, you will be responsible for:
- Tenant checks
- Deposit protection
- Gas and electrical safety compliance
- Right to Rent checks
- Rent collection and arrears handling
Landlords must also stay up to date with changes to UK rental regulations. Failure to comply can affect your ability to let the property and may impact future refinancing options.
If you are new to property investment, speaking with one of our mortgage advisers near you can help you understand how lender criteria and rental stress testing may apply to your plans.
Costs of Using a Letting Agent
Letting agents usually charge a percentage of the monthly rent or a fixed management fee. You should factor this into your rental yield calculations before committing to a buy-to-let mortgage.
When assessing affordability, lenders consider rental income against mortgage payments. Understanding your expected net rental income is important before applying. Our advisers can explain how rental calculations work under current UK lending rules for residential mortgages and investment lending.
When Using a Letting Agent May Be Beneficial
Using a letting agent may be suitable if:
- You live far from the rental property
- You have multiple properties
- You have limited time to manage tenants
- You are unfamiliar with landlord compliance obligations
Professional management can help reduce administrative burden, though it does not remove your legal responsibilities as a landlord.
Mortgage Considerations
Before deciding how to manage your property, ensure your finance is structured correctly. Some landlords choose to own their properties through a limited company, while others invest in their own name. The right structure can affect tax treatment and lender choice.
If you are expanding your portfolio or considering short-term funding before letting the property, you may also want to review options for bridging finance or commercial mortgages where appropriate.
Speak to a Buy to Let Specialist
Choosing whether to use a letting agent is part of your wider investment strategy. The right decision depends on your experience, available time and long-term goals.
If you are considering a new investment property or refinancing an existing one, contact Connect Experts to discuss your buy-to-let mortgage options with an experienced adviser.
Is Buy-to-Let a Good Investment
Buy-to-let remains a viable investment, especially with rising rental demand. However, landlords must stay informed about market conditions, tax regulations, and rental legislation. Conducting thorough research and seeking financial advice can help ensure long-term success.
A buy-to-let mortgage can be a suitable option for individuals looking to invest in property and generate rental income. However, whether it is a good investment depends on your financial position, long-term objectives and understanding of landlord responsibilities.
Before applying for a buy-to-let mortgage, it is important to assess affordability, rental demand and potential risks. Lenders will usually assess expected rental income and may require a higher deposit than for residential borrowing.
What You Need to Consider
Rental Yield
Rental yield is the annual rental income compared to the property value. A strong yield may support mortgage affordability, but you must also factor in maintenance costs, letting agent fees, and potential void periods.
Deposit Requirements
Most buy-to-let mortgages require a minimum deposit of 20 to 25 per cent. A larger deposit may provide access to more competitive interest rates.
Interest Rates and Repayment Type
Many landlords choose interest-only buy-to-let mortgages to reduce monthly payments. You must have a clear repayment strategy in place to repay the capital at the end of the term.
Tax Implications
Rental income is subject to income tax. You may also be liable for Capital Gains Tax if you sell the property at a profit. It is sensible to seek professional tax advice before proceeding.
Regulatory Responsibilities
Landlords must comply with UK regulations, including tenancy agreements, deposit protection rules and property safety standards.
