There is a lot to weigh up before taking steps to invest in a buy-to-let property:
1. First-time buyers usually need bigger deposits
Saving up for the deposit for a buy-to-let may be your biggest challenge. Lenders tend to want between 25% and 40% of the property value, but could even ask for as much as 60%.
However, the more you can save for a mortgage deposit, the more equity (or ownership) you’ll have in the property. This could make you a safer bet for lenders and might even help you to secure lower mortgage rates.
2. Other costs applicable to buy-to-let properties
Some other costs you may have to pay (but may not be exclusive to buy-to-let mortgages) include:
Stamp duty
Stamp duty is a tax on the price of a property. A couple of key points to note:
You won’t get the first-time buyer discount available in England or Scotland as the buy-to-let won’t be your main home
If you already own a property or buy with someone who does, you’ll have to pay the second home surcharge.

Surveys
To check the property’s condition. Surveys can flag up any structural issues or areas in need of maintenance. Getting a survey done makes good sense, especially on older properties, as they can uncover problems that could be costly to repair.
Solicitors’ fees
Solicitors’ fees cover conveyancing, which is the legal side of your house purchase. Your solicitor handles all the paperwork to transfer ownership of the property to you.
Landlord buy-to-let insurance
Landlord buy-to-let insurance isn’t required by law, but lenders will generally require you to have at least buildings insurance in place before they’ll consider you for a mortgage.
Specialist landlord cover can help protect you if something goes wrong with the property or the tenancy, such as loss of rent in the event of theft or a fire.
3. You need a good predicted rental income
To be eligible for most buy-to-let mortgages, lenders want to see that the rent you’re expecting to earn will more than cover the mortgage.
In most cases, they’re looking for rental income that’s at least 125% of your monthly mortgage payments – but it’s likely to be more for first-time buyers.
Lenders will also take a close look at your personal income and job situation. If your tenants stop paying rent or there’s a gap between tenancies, can you keep up with the mortgage repayments?
One way to potentially boost your chances is by putting together a solid business plan. This is especially important if you’re planning to build a buy-to-let property portfolio over time. Show lenders you’ve thought through:
What the property will cost
How much rent you’ll bring in
What kind of returns you’re expecting
Quick tip
Think about investing in an area you know well.
You’ll have a better feel for the rental market – who's looking, what they’re willing to pay, and where the best locations are.
4. Most buy-to-let mortgages are interest-only
When it comes to buy-to-let mortgages, most people pick interest-only, which means:
You're only paying off the interest each, not the actual loan amount.
At the end of the mortgage term, you still owe the full amount you originally borrowed.
The upside is your monthly payments are much lower - which can leave you with more rental income, especially if your property is earning well.
But unless you make extra payments to pay down the original loan along the way, you’ll need an alternative plan to pay it off when the mortgage term ends. You may be able to:
Be aware that property prices can go down as well as up. If the market dips, you might not sell for as much as you’d hoped. That could leave you with a shortfall you’ll need to cover.
Some buy-to-let investors choose a repayment mortgage instead. This allows you to gradually pay down both the interest and loan itself over time, usually 25 years. By the end of the term, the mortgage is paid off.
5. Being a landlord brings big responsibilities
Owning a rental property is a lot more than a straightforward investment – you’re also taking on new responsibilities.
As a landlord, you’re potentially on call 24/7 to deal with all sorts of problems. These can range from a leaking roof to a broken boiler, and replacing old kitchen appliances or sorting pest control.
One way to make life easier is by hiring a letting agent. They’ll handle a lot of the legwork, but that convenience comes at a price.
You’ll usually pay a percentage of your rent - e.g. 10% to 15% - for varying degrees of service.
Depending on what you need, they could:
Advertise your property
Find tenants and run the necessary checks. (All landlords must now legally run right to rent checks on any tenant over 18 using the online service at GOV.UK.)
Handle deposits
Collect the rent on your behalf
Do all the necessary paperwork
Take care of the property maintenance.
If you don’t maintain the property to acceptable standards or neglect to carry out repairs, your tenants can take you to the small claims court.
Quick tip
Having a list of professional tradesmen and women to do the work as needed should ensure you meet the necessary health and safety standards.
6. Tax is payable on your rental income
When you earn money from renting out property, it's treated as income and subject to income tax at your usual rate.
You’re taxed on what’s called your ‘net rental income’. This is the amount of rent left after you deduct the bills for any allowable expenses, including:
Any letting agent fees
Maintenance (e.g. the cost of replacing a broken washing machine or fridge)
Insurance (landlord insurance, for example)
Landlords used to be able to deduct mortgage interest from their tax bills but this is no longer allowed. Instead, you get a 20% tax credit based on the amount of mortgage interest you paid over the tax year.
The first £1,000 of rental income on your property is tax free.
Across the tax year, which runs from April 6, your rental income is then added to any other income you earn such as your salary to work out which tax band you’re in.
To pay any tax you owe on rent from your property, you’ll usually have to fill in a self-assessment tax return with HMRC.
Quick tip
Keeping detailed records of all your rental income and any expenses is crucial for accurate reporting and to claim all allowable tax deductions.
7. Can you cover times when there’s no rent coming in?
There might be times when your rental property is empty, or your tenants fall behind on payments. These gaps are known as void periods and underline how important it is to have a safety net.
Having money stored away in a savings account could give you the buffer you need. If you're able to, it makes sense to put aside three months’ rent to cover emergencies.
When considering mortgage affordability, it’s important to know that your home or property may be repossessed if you do not keep up with your mortgage repayments. Therefore, you need to ensure that you’re comfortable with the monthly repayments for your agreed term.
All mortgage applications are subject to status and lending criteria, and are based on your individual circumstances. Applicants must be 18+ and a UK resident.
