What is a buy-to-let property?

Buy-to-let is an investment strategy where you purchase a property specifically to rent it out to tenants. It can be a rewarding investment, offering both ongoing income and potential property value appreciation over time.

The aim is to secure a rental income that exceeds your outgoing costs. This includes covering the property's maintenance, letting agent fees (if applicable), and monthly mortgage payments. It’s important you know what you’re getting into as there are some key differences when it comes to purchasing a buy-to-let property, compared with the usual process of buying a house.

Buy-to-let: The facts

Buy-to-let is when a person or company purchases a property for the purpose of 'letting' it out to a tenant. Unless you are a cash buyer you will need a specific buy-to-let mortgage when investing in a rental property.

A buy-to-let owner is known as a landlord, and the properties they invest are often residential homes such as flats, or houses. However, there are some landlords who concentrate on commercial properties, renting out to businesses rather than individuals.

In 2023, the ONS recorded there were approximately 5.4 million private renters in the UK. With the cost of living increasing and many people either choosing not to buy, or unable to afford to, we are now seeing 15 households chasing every rental home in the UK (according to data from Zoopla). This makes buy-to-let an investment worth considering.

How is a buy-to-let mortgage different?

If you want to take out a mortgage for a property that you plan to rent out, you’ll need a specific buy-to-let mortgage. This is because mortgages for buy-to-let properties are riskier for lenders, see below why.

Interest-only mortgages

One of the risks is that buy-to-let mortgages are usually interest-only. Interest only mortgages allow you to keep the monthly repayments down as the buyer, however, at the end of the mortgage term, the purchase price hasn’t been paid off, so you still don’t own the property outright. This means you’ll either have to remortgage, sell the house, or pay it off another way.

Higher fees on your mortgage

Because of this greater risk, lenders tend to charge higher fees than on a regular mortgage. Interest rates are also higher, while you’ll also be expected to put down a higher deposit. The minimum deposit is usually 25% of the property’s value, although this can vary between 20-40% with different lenders.

Financial strategy and end-of-term options

During the mortgage term, you can generate income from renting out the property. This income can be used to cover the interest payments. However, since the capital isn’t paid off during the term, you should plan for the end of the mortgage. You must be prepared to sell the property, use savings to pay off the loan, or remortgage to settle the outstanding balance.

Rent based mortgage calculation

A unique feature of buy-to-let mortgages is that the amount you can borrow is based on the potential rental income rather than your salary. This means that if the property is in a desirable location or is large, you can charge higher rent, potentially qualifying for a larger mortgage.

Mortgages are less regulated

The final significant difference between buy-to-let and regular mortgages, is that buy-to-let lending doesn’t have to be, and isn’t typically, regulated by the Financial Conduct Authority (FCA). There are exceptions though and finding a mortgage supplied by an FCA authorised lender could give you greater peace of mind.

What to do if you need to switch to a buy-to-let mortgage

Becoming an accidental landlord can happen unexpectedly. Perhaps you need to relocate but aren't ready to sell your current home, or you've come into ownership of a property through inheritance. Whatever the reason, if that property currently has a standard, owner-occupier mortgage, some steps are required to switch to a buy to-let mortgage.

Notify Your Mortgage Lender

First and foremost, inform your mortgage lender of your intention to rent out the property. This step is critical, as failing to notify them could invalidate your existing mortgage agreement.

Explore Your Options

Once you've notified your lender, the next steps will vary depending on their policies. Here are some possible outcomes:

Remortgaging: You may need to switch to a new buy-to-let mortgage. This could involve remortgaging, which might also mean changing lenders. It’s worthwhile comparing different lenders to find the best interest rates.

Consent to let: Your current lender may offer what's known as 'consent to let.' This allows you to maintain your existing mortgage but grants permission to rent out the property, usually for a limited period only.

Additional considerations

  • Interest Rates: Buy-to -let mortgages often have higher interest rates than residential mortgages.

  • Fees and Costs: Remortgaging or obtaining consent to let may come with additional fees.

  • Insurance Adjustments: Modify your home insurance to a landlord insurance policy to protect your investment appropriately.

How much can I borrow if I’m buying to let?

If you can't buy the property outright with cash, the maximum amount you can borrow on a buy-to-let mortgage depends on how much rent you can charge for the property. Generally, lenders will require your rental income to be around 25-30% higher than the mortgage payment.

Is there a minimum salary requirement for a buy-to-let mortgage?

Most lenders will require you to earn at least £25,000 a year to qualify for a buy-to-let mortgage. This salary requirement helps ensure you can manage the financial responsibilities of owning a rental property and helps guarantee that the mortgage is affordable even during periods when the property is vacant.

Are there buy-to-let mortgage options for first-time buyers?

Yes, there are indeed buy-to-let (BTL) mortgage options specifically tailored for first-time buyers. If you're a first-time buyer living in an area with steep property prices, acquiring a rental property in a more affordable location could be a strategic way to earn additional income while working towards saving for a deposit.

Challenges to Consider

  • Higher Deposits Required: As a first-time buyer, you might encounter fewer available options for BTL mortgages, often necessitating a larger deposit.

  • Stamp Duty: Unfortunately, first-time buyer Stamp Duty relief doesn't extend to buy-to-let purchases. You do escape the typical 5% surcharge on buy-to-let purchases though.

Opportunities for first-time buyers

Despite these hurdles, options do exist for first-time buyers interested in a buy-to-let investment. Several lenders are now offering mortgage products that cater to new buyers, including those who are self-employed, retired, or older.

Many of these options include flexible rate terms with no required minimum income, making them accessible even if your regular cash flow varies.

Buy-to-let property FAQs

  • Can you live in your buy-to-let property?

    With a standard buy-to-let mortgage, living in that property isn't permitted. These mortgages are designed specifically for investment purposes, meaning they require the property to be rented out to tenants rather than used as a personal residence. This restriction is set by lenders as part of the mortgage terms.

  • Can you rent out your buy-to-let property to a family member?

    Most mortgage lenders require you to inform them if you plan to rent your property to family, you might need a specific family buy-to-let mortgage. These products are tailored for letting properties to relatives and often come with different terms compared to regular buy-to-let mortgages, typically demanding a larger deposit.

  • What is a portfolio landlord?

    A portfolio landlord is someone who owns four or more rental properties. This status can significantly influence your ability to secure a buy-to-let mortgage. The larger your portfolio, especially if you have numerous mortgages, the tougher the scrutiny from lenders.

What is the best buy-to-let property type?

Quite simply, the best properties for buy-to-let are ones in a desirable location. Whether this is because of the area itself or the transport links on offer, if no one wants to rent your property then you’ve got a major problem on your hands. If there isn’t local demand for the type of property you’re looking at, it’s probably best avoiding it. For example, you might be interested in a flat above a restaurant, but if the biggest demand in the area is for young families, you may struggle to let it out. Blocks of flats with lots of other buy-to-let investors can be something to avoid, as the competition could mean rents are driven down, or even your property remaining empty.

Tips for buying a buy-to-let

Understanding the costs of a buy-to-let property

There is a spectrum of costs involved with a buy-to-let investment. Here's a breakdown to help you plan effectively.

Initial purchase costs

  • Deposit and mortgage fees: As with any property purchase, you'll need to pay a deposit and any associated mortgage fees.

  • Stamp duty land tax (SDLT): On 31st October 2024, the government announced they were adding an additional 2% to every SDLT band on buy-to-let properties above £40,000 if you already own another property. This means, you'll pay:

    Proportion of property valueRate for additional property
    Up to £250,0005%
    £250,001 to £925,00010%
    £925,001 to £1.5 million15%
    Over £1.5 million17%

    Use our stamp duty calculator to work out the SDLT payable on your additional property.

    As of 1st April 2025, there will be an additional threshold banded added to the stamp duty rates. For more information on what this will mean for you, read about how stamp duty is changing in 2025.

Preparation and renovation costs

  • Renovation and improvements: Before renting out your property, you may need to invest in renovations and improvements to make it tenant-ready.

Ongoing financial obligations

  • Income tax on rental income: You'll be required to pay income tax on your rental income. Like any self-employment income, allowable expenses—such as maintenance, insurance, letting agent fees, and any utility bills you cover—are deducted from your taxable allowance.

  • Mortgage interest tax relief: Previously, mortgage interest and buy-to-let fees could be offset against income tax at up to 45%. This relief has now been capped at 20%. It's advisable to seek specialist tax advice if you believe these changes will affect your investment.

What are the landlord responsibilities with buy-to-let properties?

If you’re wondering whether you’re ready to take on the role of being a buy-to-let landlord, it’s a good idea to know your legal responsibilities: you may find it useful to contact a lawyer who specializes in Landlord and Tenant law for any specific advice. Things to be aware of include:

Insurance

With your purchase complete and a new set of keys in your hand, you now have some new responsibilities as a landlord. This includes arranging buildings insurance, which is necessary for a buy-to-let mortgage and can protect you in the event of something going wrong with your property. It’s also a good idea to get landlord insurance and rent guarantee insurance to give yourself some added protection.

Contract

You need to provide a contract for your tenant, which most commonly comes in the form of an Assured Shorthold Tenancy (AST). This gives your tenant the legal security that they can live in the property for the fixed term specified, or on a rolling basis.

Right to rent

As the landlord, it’s up to you to check that any prospective tenants have the right to rent property in the UK.

Tenancy deposit protection

You need to place your tenant’s deposit in a government-backed tenancy deposit protection scheme (TDP), then provide them with details of where their deposit is being kept.

Gas and electric

As well as regular checks on wiring and electrical appliances, you need to carry out an annual gas safety check, covering all of the gas appliances in the property. When this has been done, you must provide your tenant with a copy of the certificate.

Energy performance certificate (EPC)

EPC’s are valid for ten years, and your property must have an up-to-date certificate before you can rent it out. A copy should also be supplied to your tenant.

Fire

Protecting your tenants against the risk of fire is very important. Soft furnishings and furniture should meet fire safety regulations, while fire alarms and smoke detectors should be fitted and in working order. Carbon monoxide alarms should also be fitted in rooms with gas appliances.

Hands-on or delegated management

Decide whether you want to be a hands-on landlord or would prefer to hiring a property management agency. Managing the property, sourcing tenants, and collecting rent can all be time consuming. An agency can handle these tasks, however, this will reduce your profit margin.

Staying up to date with tenancy laws

Laws change, and staying informed is a must. Changes in tenancy law can significantly impact your profits and how you handle issues such as evictions. Consider subscribing to a property law newsletter or joining a landlord association for updates.
