What is a buy to let mortgage?

Buy to let mortgages are designed to help you buy a property to rent out to other people, rather than live in yourself. The amount you can borrow depends on the deposit you can put down and the amount of rental income you expect to earn from tenants. There are many different types of buy to let mortgages, such as single unit family lets, holiday lets, House of multiple occupancy (HMO) and Multi-unit freehold blocks (MUFB). Our expert brokers can assist with any type of buy to let set up you require.

Are buy to let mortgages interest only?

Yes, most buy to let mortgages are interest-only, meaning monthly payments only cover interest. The loan balance is paid at the end of the term, typically through the sale of the property. However, it is possible to get a BTL mortgage on a repayment basis.

How do lenders test affordability?

Lenders typically use your expected rental income to calculate how much you can afford to pay in monthly interest payments. Some can also take into account personal income to make up any shortfall in this rental income, should it be required, often know as "top slicing".

Lenders ask for your rental income to cover between 125% to 140% of the monthly interest payments but each lender has their own requirements.

Use our buy to let mortgage calculator for an idea of how much you could afford to borrow based on rental income. Our expert buy to let mortgage brokers can help you estimate how much rental income you would need to make from a property in order to get maximum borrowing levels.

How much deposit do I need for a buy to let mortgage?

Buy to let mortgages are available from as little as 20% deposit with more options becoming available with a 25% deposit. However, the rental income needs to stack up in order to borrow the remaining 75-80%, in some cases more deposit is required in order for the rental affordability to work.

Am I eligible for a BTL mortgage?

You need to meet certain criteria to be eligible for a buy to let mortgage. Although exact details vary between lenders, some key criteria are as follows.

  • Age: You will typically need to be at least 21 years old, although some lenders can offer mortgages below this limit. There is an upper limit with some lenders for BTL products, but options are very flexible.
  • Location of residence: If you are purchasing a buy to let property very close to your current residential home some lenders will have further questions surrounding this but options are available. Buy to let mortgages are also available to those who are currently living outside of the UK
  • Credit history: Many lenders can be flexible when it comes to less than perfect credit. They will typically consider the age, severity and amount of any credit problems and may overlook less severe issues.
  • Property ownership: It is not a requirement to own your own home before you purchase a buy to let. There are a number of lenders who allow a first time buyer, first time landlord scenario.
  • Personal income: Some lenders do have minimum income requirements, if so this is typically £25,000 per year, separate from your rental earnings. However, there are lenders who do not have this requirement, especially for experienced landlords.

Whatever your circumstances, our expert buy to let mortgage brokers can let you understand your eligibility and help you find the best financing for your needs.

BTL mortgages interest rates are similar to residential products but do typically come with higher fees. Lenders require larger deposits compared to residential as they are typically higher risk.

You may also face additional costs as a landlord, such as letting agent fees and higher taxes.

Our specialist brokers can help you consider all the costs involved in taking out a buy to let mortgage so you can make the most informed decisions for your investment.

As well as interest rates, it's important to compare the different fees charged on buy to let mortgage deals, as they can increase your overall costs. These include but aren't limited to:

You and your spouse are considered a single 'unit', so you can't avoid paying the additional 5% by having your spouse buy the second property in their name.

Stamp Duty Land Tax Examples

Purchase price SDLT
£400,000 £30,000
£550,000 £45,000
£1,000,000 £93,750
