Buy to Let Advice
Buying a property to rent out can provide rental income and a long-term investment, but it also comes with costs, tax obligations and legal responsibilities. Before investing in buy-to-let, it is important to understand the purchase process, mortgage requirements, potential rental yield and the rules that apply to landlords.
This guide explains what to consider when buying a buy-to-let property, including Stamp Duty Land Tax (SDLT), rental income tax, landlord registration and ongoing property management. It also covers the legal checks involved in buying a rental property and the changes landlords need to prepare for.
- Budget for the full cost: Factor in your deposit, buy-to-let mortgage fees, conveyancing, Stamp Duty Land Tax (SDLT) or Land Transaction Tax (LTT), insurance and ongoing maintenance.
- Assess the rental potential: Research local rental demand and calculate your expected rental yield, allowing for mortgage payments, other expenses and periods without tenants.
- Understand the tax implications: Consider tax on rental income, restrictions on mortgage interest relief and the new property income tax rates due from April 2027.
- Prepare for new requirements: Making Tax Digital for Income Tax is being introduced in stages, depending on qualifying income. Private landlords in England should also prepare for the new Register your rental property service.
- Know your legal responsibilities: Check the requirements for tenancy agreements, deposit protection, property safety and landlord compliance before letting your property.
Should I buy a buy-to-let property?
Buying an investment property is a significant financial commitment. Before proceeding, consider whether you can afford the deposit, mortgage payments, purchase costs, and ongoing expenses. These may include letting agent fees, repairs, refurbishment, cleaning between tenancies, tax, buildings and landlord insurance, and service charges or ground rent if the property is leasehold. You should also allow for periods when the property is empty and not generating rental income.
What are the disadvantages of buy-to-let?
The main obstacle to buy-to-let is that you won't be able to get one at all unless you already own your primary residence. This is because buy-to-let mortgages have certain perks (including interest-only deals) that are not available to owner-occupiers, and lenders are concerned that you might purchase with a buy-to-let mortgage and then move in. This would breach the terms of your mortgage. However, eligibility criteria vary by lender, and some lenders accept first-time landlords who do not own a home.
What is the minimum income for buy-to-let?
Most lenders require a minimum personal income of £25,000, even though the rental income pays the mortgage, not you personally.
How much rent is required on a BTL?
Your mortgage deal will require a regular rental income of at least 125% of the monthly mortgage payments, but some require as much as 145%. This will make sure your mortgage is covered, and you'll have some left over for maintenance, management, agency fees, and, if the property is leasehold, ground rent and service charges.
Is it worth getting a buy-to-let now?
The higher cost of borrowing over the last few years has put a number of landlords off. The tax you pay on rental income depends on your taxable income, applicable allowances and the relevant property income tax rules. You should consider your expected after-tax return when assessing whether the investment is worthwhile. However, if you trust the economists who generally agree that property prices will rise significantly over the next 5 years, then you only need to break even each month, as the value (and therefore your equity) increases. You'll still have to pay CGT when you sell the property.
Read on for more information on the tax you'll pay as a landlord.
Choosing the right property
You'll need to consider the location you're buying in, the type of property you're looking at, and your ideal tenants. If you want to buy a large house to let to students, you'll need to make sure you're buying a suitable property in a popular student area. If you can afford a smaller property and want to maximise your yield, you might want to buy a higher-spec flat in a location popular with young professionals. Or, if you want a family who will stay for a few years and save you the hassle of finding new tenants and redecorating every 12 months, you'll want to find a property with a garden in a good school catchment area.
If you pick the wrong property or location for your target tenants, you may struggle to fill the property. Every day or week the property is unoccupied, you'll lose money.
You'll need to see what similar properties cost to rent so you can budget your expenses within your earnings.
If you plan to use a letting agent to manage the ongoing tasks, such as rent collection, you've got more freedom over where you buy, so you can choose a location with high rental demand and a high rental yield. However, if you want to save money by managing the property yourself, you'll need to choose somewhere that is closer to you or easier to travel to.
You can also maximise your investment by choosing a property which could benefit from renovation, but make sure you only do this if you have the available budget to renovate the property and cover your costs while the property is empty for the work to be carried out.
Speak to several estate agents to find out what type of property is in shorter supply than demand in the area.
Choosing the right mortgage
Most buy-to-let properties are bought with an interest-only mortgage; the interest rate is usually higher than on a residential mortgage, and the eligibility terms are usually different. You can check these with your lender, or speak to one of our 100% impartial mortgage brokers who can find you a selection of mortgage products from various lenders which best meet your needs.
How much deposit do I need to put down for a buy-to-let?
You'll need at least a 25% deposit for a buy-to-let. The higher your deposit, the lower your monthly repayments will be, so you'll keep more of the rent as income. However, if you have more than enough for a 25% deposit, it may be financially beneficial to buy more than one property, with the minimum 25% deposit.
Splitting the money and income across two or more properties of different types or locations helps to diversify your property investment portfolio, which could make your income more stable. For example, if you have to evict one set of tenants and do work on the property, you'll still have the income from the other.
Before the 1st of June 2024, buy-to-let properties were subject to multiple dwellings relief, which reduced the tax paid when buying multiple dwellings in a single transaction. This has been abolished.
What fees are involved in a buy-to-let mortgage?
When comparing buy-to-let mortgages, check the interest rate and any fees you may need to pay. These can include:
- Mortgage valuation fee
- Mortgage broker fee: If you use a broker, they may charge you a fee or receive commission from the lender.
- Mortgage booking fee: Also known as a reservation fee.
- Mortgage arrangement fee: Also known as a product fee. This may be paid upfront or added to the mortgage, depending on the lender's terms.
- Mortgage interest and repayments: Repayments on a repayment mortgage cover interest and capital, whereas interest-only payments cover the interest.
- Exit fee
- Early repayment charge: May apply if you repay the mortgage during a period specified in your mortgage terms.
Other purchase costs
Other purchase and set-up costs may include conveyancing fees and disbursements, Land Registry fees, Stamp Duty Land Tax (SDLT) or Land Transaction Tax (LTT), property searches, a survey, buildings and landlord insurance, initial repairs or decoration, fixtures and fittings, furniture if you intend to let the property furnished, an Energy Performance Certificate (EPC) and any required gas safety checks and certification. Not every cost will apply to every property.
Many of your running and maintenance costs can be written off as business expenses if they are wholly and exclusively incurred as a result of letting the property.
Is it difficult to get a buy-to-let mortgage?
They are considered higher risk than residential mortgages, so the criteria are more stringent. You'll need a good credit rating, as with most other borrowing. You'll also need a bigger deposit, a rental income of 125% - 145% of the monthly repayments, and to be able to comfortably afford your repayments on any other debts you have, including your own mortgage.
What are the tax changes for landlords in 2026/27?
Landlords need to consider how tax affects the cost and profitability of a buy-to-let property. Alongside the existing rules for declaring rental income and claiming allowable expenses, new property income tax rates are due to take effect from 6 April 2027. Making Tax Digital for Income Tax is also being introduced in stages, while private landlords in England will need to prepare for the new Register your rental property service.
The rules depend on factors such as how the property is owned, the landlord's qualifying income and where the property is located. The sections below explain the main changes and when they apply.
Stamp Duty Land Tax on the purchase
When buying a buy-to-let property in England, you will usually pay the higher rates of Stamp Duty Land Tax (SDLT) if the purchase falls within the rules for additional residential properties. These rates generally apply where the relevant property interest is worth £40,000 or more, subject to the detailed rules and exceptions. SDLT is calculated using the applicable rate bands rather than applying a single rate to the entire purchase price.
The amount payable depends on the purchase price, the buyer's circumstances and whether any exemptions or reliefs apply. Non-UK residents may also be subject to an additional surcharge. Use our Stamp Duty Calculator to estimate the amount payable.
Portion of the purchase price | SDLT rate for an additional property |
|---|---|
Up to £125,000 | 5% |
£125,001 to £250,000 | 7% |
£250,001 to £925,000 | 10% |
£925,001 to £1.5 million | 15% |
Above £1.5 million | 17% |
For example, if you buy an additional residential property for £300,000, the SDLT would usually be £20,000, calculated as 5% on the first £125,000, 7% on the next £125,000 and 10% on the remaining £50,000.
The exact amount payable depends on the transaction and whether any exemptions or reliefs apply. Overseas buyers pay an additional 2% surcharge, so if you are buying a rental property or a holiday home from abroad, you will pay 5%, 10%, 15% and 17% on each band.
The standard SDLT nil-rate threshold for residential property in England and Northern Ireland reverted to £125,000 from 1 April 2025. Different thresholds and reliefs may apply depending on the buyer's circumstances. Use our Stamp Duty Calculator to work out what you'll need to pay. If you are buying a property in Wales, Land Transaction Tax applies instead.
What are the tax changes for landlords in 2027?
From 6 April 2027, the property income tax rates for individuals in England and Wales are due to increase by two percentage points, to 24% for the basic rate, 44% for the higher rate and 49% for the additional rate. These rates apply to taxable property income, not automatically to every pound of rent received, as allowable expenses and the landlord's wider tax position affect the amount subject to tax. Check the rules that apply to your circumstances when calculating your expected after-tax rental income.
Property income tax band | Rate from April 2027 |
|---|---|
Basic rate | 24% |
Higher rate | 44% |
Additional rate | 49% |
The change applies from the 2027/28 tax year. It is important to factor in higher rates when calculating rental profit when deciding whether a property is a worthwhile investment.
Tax treatment differs for properties held through limited companies. If you are comparing personal ownership with company ownership, seek professional tax advice before purchasing.
Making Tax Digital for Income Tax: what landlords need to know
The government's Making Tax Digital for Income Tax is changing how some landlords record and report their rental income and expenses to HMRC.
Those who must use the service will need compatible software to keep digital records and send quarterly updates to HMRC.
The requirements are being introduced in stages according to qualifying annual income from property and self-employment. The start date depends on your qualifying income for the relevant tax year, calculated before expenses:
- From 6 April 2026: Landlords with qualifying income over £50,000 must use Making Tax Digital for Income Tax, subject to the applicable rules and exemptions.
- From 6 April 2027: The requirement extends to those with qualifying income over £30,000.
- From 6 April 2028: The threshold reduces to qualifying income over £20,000.
These thresholds are based on qualifying income, not rental profit after expenses. If you receive income from both property and self-employment, the relevant income is combined when assessing whether you meet the threshold.
Not every landlord will need to use Making Tax Digital immediately, and exemptions may apply. Check the latest HMRC guidance on Making Tax Digital for Income Tax to establish when the rules apply to you.
Income tax on the rental profits for individuals
This is the tax payable on your total income, which will include your rental profits plus any additional income, including salary, self-employed income, pensions, benefits in kind, and redundancy payments. The first £1000 of your income from property is tax-free. This is called the 'property allowance'.
If your rental profits are between £1,000 and £2,500 per year, contact HMRC directly. If your rental income is £2,500 to £9,999 after allowable expenses, or £10,000 or more before allowable expenses, you must report it using a self-assessment tax return.
Tax relief on mortgage interest
Individual landlords who pay Income Tax generally cannot deduct residential mortgage interest and other qualifying finance costs in full when calculating their taxable rental profit. Instead, they may qualify for a basic-rate tax reduction on eligible finance costs, subject to the relevant rules.
This can mean that the tax treatment of mortgage interest differs significantly between landlords who own a property personally and those who own it through a limited company. The effect on your overall tax liability will depend on your circumstances, so seek professional advice before choosing an ownership structure.
Income tax on the rental profits for limited companies
If the property is owned via a limited company, tax is paid at 19% for companies with profits under £50,000 per year. The main rate is 25% but will only apply in full to companies with profits over £250,000.
Companies with profits between £50,000 and £250,000 will receive marginal relief (3/200), so they will pay between 19% and 25% on their total taxable profits.
Associated companies will have the thresholds adjusted. For example, a company with three other associated companies will have the thresholds divided by 4. Marginal relief on the main rate of 25% would apply to company profits between £12,500 and £62,500, after which the full rate would apply.
For a company that owns a rental property, qualifying mortgage interest and finance costs are generally treated as expenses when calculating its taxable profits, subject to the applicable corporation tax rules and restrictions. Repayment of the mortgage capital is not an allowable expense. The tax treatment differs from that for individuals who personally own residential rental property.
If a company, partnership (where any of the partners is a company), or a collective investment scheme, owns a property worth more than £500,000, it may also be liable for Annual Enveloped Dwellings Tax. However, there are some reliefs and exemptions which may apply. Speak to a tax advisor to determine whether you would be financially better off by setting up a property company for your investments.
Allowable expenses
You may be able to deduct certain costs incurred from letting a property when calculating your taxable rental profit. Allowable expenses must comply with HMRC's rules, and their treatment depends on the type of cost and how the property is owned.
- landlord insurance
- costs of services, including the wages of gardeners and cleaners (as part of the rental agreement)
- letting agents' fees
- legal fees for leases of a year or less, or for renewing a lease of less than 50 years
- accountant's fees
- rents, ground rents and service charges
- direct costs such as phone calls, stationery and advertising for new tenants
- (If included in the rent) water rates, council tax, gas and electricity
Capital gains tax on the sale proceeds
When you sell a property, you pay capital gains tax on the 'capital gains', that's the increase in the value of the property. If you bought the property for £225,000 and sold it for £260,000, your capital gains would be £35,000.
You would pay CGT at 18% on any of the £35,000 which falls within your basic rate tax allowance, and 24% on any of the capital gains which bring your personal income above the basic rate. Higher-rate taxpayers pay 24% on all gains from residential property disposals.
Capital gains tax applies to UK residents and foreign investors.

Register your rental property: new landlord requirements
The Renters’ Rights Act introduces a new requirement for private landlords in England to register themselves and their privately rented properties through the government's Register your rental property service.
The service will begin rolling out regionally from 15 December 2026. Landlords must register within the registration period for their property's region.
Who needs to register?
Private landlords letting properties in England under qualifying assured or regulated tenancies must register. This includes individual landlords, joint landlords and organisations that let residential property, subject to the applicable exceptions.
Each joint landlord must register themselves, although one joint landlord can register the property and invite the others to join the registration.
How much does landlord registration cost?
The service has an annual fee of £65 per property, which the government states is tax-deductible. Landlord registration itself is free, but each property incurs a fee when registered and annually thereafter. Fees during the initial rollout will be adjusted according to the registration date.
What information will landlords need?
Landlords will need to provide personal or organisational details and information about each property. This includes relevant tenancy details, property information and evidence of applicable safety and compliance documents, such as:
- Gas safety documentation, where the property has a gas supply.
- Electrical safety documentation.
- An Energy Performance Certificate (EPC).
- Relevant property licences, where applicable.
Some information can be supplied after the initial registration, but outstanding information must generally be provided within 28 days. Landlords must also update information when it changes or a certificate expires.
Landlords remain legally responsible for registration and keeping their property records up to date, even if they ask a letting agent or property manager to help.
When must landlords register?
The registration service will launch region by region, with each area having a three-month registration period. The East of England registration period is scheduled to run from 15 January to 14 April 2027. Check the official guidance for the relevant local authority and any updates to the rollout timetable.
Failure to comply can result in financial penalties, so landlords should prepare the required documents and make a note of their registration deadline.
Managing your rental property
Many buy-to-let landlords manage their own properties as a business. However, if you are already working full-time or have many properties to manage, you may choose to pay a letting agent to manage things for you.
They can just find your tenants, or they can handle ongoing management, including inspections, maintenance arrangements, and rent collection. If your margins allow, this option may be preferable for new landlords seeking the peace of mind that comes with letting experienced professionals handle their legal obligations.
- Assured tenancy agreements.
- Property defect reports.
- Expert witness services.
- Property disputes and mediation.
- Expert legal advice tailored to your circumstances.
- Fixed, competitive legal fees from £748 INC VAT.
