    What Is a Buy-To-Let (BTL) Mortgage?

    A buy-to-let mortgage is a mortgage that caters to those who want to buy a property to rent out instead of living in it.

    How Do Buy-To-Let Mortgages Work?

    Buy-to-let mortgages work in that the lender who rents out the property only pays off the monthly interest portion of the mortgage and settles the capital payable at the end of the agreement term.

    Who Can Get a Buy-To-Let Mortgage?

    To get a buy-to-let mortgage, you need to be 18 or over; however, in most instances, you need to be over 21. 

    Most lenders have an upper age limit for buy-to-let mortgages, and in general, it’s 75 years old; some providers will push this up to 85 years.

    You should also have a good credit score and earn more than £25,000 a year.

    Buy-To-Let Mortgages for First-Time Buyers

    Buy-to-let mortgages are available to first-time buyers; however, it’s more complex than for non-first-time buyers.

    As a first-time buy-to-let applicant, you’ll probably need a bigger deposit than other buyers and will need some income to cover initial repayments as you’ll not be receiving a rental yet.

    First-time buyers will also not qualify for first-time buyer relief, so they’ll be charged the same rate as other buyers who’re not buying their first home.

    Buy-To-Let Mortgage Rates

    Buy-to-let mortgage rates typically increase depending on the price of the property being purchased; on average, the rates are 3.4%.

    How Much Can I Borrow Using a Buy-To-Let Mortgage?

    How much you can borrow using a buy-to-let mortgage will depend on the rent you could charge for the property you want to purchase.

    Generally, your income should be 125% of your repayment amount.

    How Much Deposit Do I Need for a Buy-To-Let Mortgage?

    The deposit you need for a buy-to-let mortgage is 25%; however, the deposit required can range from 20% to 40%.
